The real thing is once again available new from the ARRL at:
http://www.arrl.org/catalog/?item=9123

If you want a software version, you can find it at:
http://www.peeblesoriginals.com/projects-instructions.html

It will calculate cylindrical and spiderweb coil turns required as well 
as capacitance required for frequency of choice.  Note that it requires 
Excel to work.

Back in the early ‘50s I used to ride with a friend who had a Black Shadow -
awesome bike!  At that time I had one of Indian’s V-twin shaft-drive
prototypes that they made for the US Army in “42??.  He used to blow me away
for the first 25 miles but it seemed to develop a bad case of croup after
that and I was usually in the lead on the final leg.

Only had limited experience with brit bikes.  An unremarkable time with a
125 James and an all too short one with a 500cc BSA Gold Star (lost the job
necessary to make the payments).

Now if they would only bring back the Morgan Plus Four.

Subject: GB> Glass Piston  Caps

What is a typical voltage rating for a glass piston cap? How would one 
estimate? Is the tempco positive, negative or NPO?

I glommed onto a handful of small boards that each have one very nice cap of 
this sort. They are marked only "VOL TP60CAX". Adjustment is by a small 
Allen wrench and the range, according to my measurement, is about 0.7-65 pF.

Can't answer your question, but I'll

Maybe you can find information

Hey Ralph. Liked the article on the supply. I may have enough
ferrite bar stock here to experiment at some point on that
same type of project.

But looking for info I ran across a commercially available 1.5 KW
switcher at wattsunlimited.com. Reading along I found this hidden
in the fine print - "For the pre-built unit, the PS-2500A may be
customized by the user for any lower voltage by removing turns
from the secondary winding of the toroid stack" so looks like it
is fully customizable. It is also available as a kit, which would
make it even more so.

http://wattsunlimited.com/  It's not cheap, though.

Yep; I saw that when they came out with it.  It's a very nice design.
As I quickly found out, there are a lot of little details that you have
to take into account in order to build something that handles that
amount of power if you want it to work reliably.  Things tend to vanish
in a brilliant ball of flame accompanied by very loud noises and flying
shrapnel if the design is not excellent!

Subject: RE: GB> National NC57-B  BFO

I don't know that particular receiver, but other vintage receivers that I've
worked on used ordinary paper caps in frequency-sensitive circuits -
especially down at the 455 kc/s I.F. 

Those things can be awful when they age and dry out. Keep in mind that
bypass caps in an oscillator can also affect the frequency. 

Something else that I've run into is a resistor drifting high - usually a
dropping resistor in the B+ to the oscillator. The oscillator will work in
spite of the low B+, but the voltage becomes very unstable (and usually
temperature-sensitive).

From: "Michael N. Hopkins" 

Subject: GB> Fixin' NC-57 BFOs by Radiator Cap Method.

I've NC-57s here but I misplaced the manual so I reviewed an article in
73 magazine.

The BFO is half a 6SL7 with 150 regulated volts on the plate and 220pf in
parallel to a center tapped coil.  This diagram shows it tuned by moving
the BFO slug in and out a la Hallicrafter's S-40.  If that's so, you
might just have it too far out or in.

I've two NC-57, but one is a marine, aka AC/DC and it seemed to me one of
them had a cap tuned beat oscillator.  But no matter.  All of it is
subject to the Radiator Cap Rule of auto repair:  In some cases it's best
to take off the radiator cap and run in another car below it.  I'll not
go quite that far wih the far with mine.

But in that spirit, W6GXN and I suggest you replace your triode BFO with
an N-channel mosfet.  He swapped 150 volts for 12, added a 1K source
resistor bypassed by a 0.1uf cap and tossed the 10K at the plate for a
12mh choke bypassed by 0.22uf.

That's all he did.  He says it works fine and it gives you a spare
triode.

But you probably don't need a spare triode.  There are many reasons to
restore a vt RX with all vacuum tubes, but performance isn't one of them.
 And a pristine NC-57 will be worth about as much as some other NC-57, or
the S-53 I once had with only the Heptode Mixer still using a heater.  It
was better than the original, of course.  But none of them are worth
much.  You can buy a restored Model T for far less than it costs to
restore one. 

Now I do admit the vt is still a prince, if not a king in the front end. 
A rig with no RF stage does much better with a tube up front.  The NC-57
is a closer case in that it has a 6SK7 up there.  Those are noisy, but
455 superhets don't perform so well above 10mc that you'd notice.  It's
6SB7 LO will be drifting along, too.

Still, it is as W6GXN says in "Old Receivers--A Hidden Gold Mine," 73
Magazine, (cite lost but in the newer, large format era.)  "Once one
starts down the road of improvement, the options are endless, and finally
one finds out that he should have started from scratch."

If you consider the FET an improvement, and want to fix the HT BFO, it's
the 150 volts to the plate thru a 10K and a 22K grid leak.  Then, from
the plate find a 0.01uf cap and from the grid a 270 pf.  Those two go to
a 220pf across them and, in parallel with it, the center tapped coil.

W6GXN was working with an S-40 and an NC-57 in very rough condition, by
the way.  So perhaps he offended orthodoxy less than I will when he put
in transistor audio.  I'm going to do that on mine, and maybe a SS IF in
one too.  But I'll keep the AC-DC stock, at least as to tube lineup,
'cause it so irritates the pusilaminous upgraders when I don't use a
transformer other than the one on the pole.

Subject: GB> National HFS for S/T

Just came back from where I stack my NC-57s and I found an HFS.  Anyone
want it?

This latter day (late '40s) rig is really a tuner for 27 up to about
250mc.  It has plug-in front ends and oscillators for the various slices
of the coverage in a holder inside the top.   A 6AK5 leads off and it
ends either in a regnerative RX or in a 10.7 take off which fed my
National NC-57 nicely.  It fits right on top too.

But I'm a Tecraft person and have more converters than my cats have
fleas.  So I took it to Dallas HamCom last year, with $60 on it, and drew
no nibbles.  That says I should E-bay it, I suppose, but I'm irresolute. 
I'll just take it to the central Texas Belton Hamfest next month, then to
Dallas in June if it survives Belton.

That said, we were talking about these recently so someone might want to
trade it for something or otherwise work out a deal.  It's clean but old,
works but needs work, and the cover, for some reason, is gone from the
bottom of the legendary 500 mark National dial.  It works, however.  It
needs 170 or up HT and 6.3 in the back via a 4 prong jack I've mated to a
4-prong socket inside a pill bottle.  Period corectness is not a goal at
ab5L and I don't want to let my Eico bench supply go with the HFS  (the
supply is missing a bezzle anyway, collectors.)

But the HFS is nice and has original manual.  So let me know before late
next month if you want it.

> Lets do our best to not let THIS future come to pass....

There is something about this that kinda bothers me, though. I have long 
felt that if you HAVE to have revival meetings, bang the drum,  get out there
and  exercise your RESPONSIBILITY etc. etc., your product might be some-
how lacking, or at least thought of incorrectly, or positioned in the market
incorrectly. 
Altho there is a lot of pressure on the high VHF and up, bands, i don't really
see any increase in users clammoring for HF channels or even VHF. There IS
a great deal of increase in distribution by means of direct connection and
by UHF and microwave.
Personally, i just don't see it as very attractive to get on the air with contem-
porary ham radio products and exchange numbers, even with someone far away,
so i will probably sit out this call for a Revival.
One thing you always have to face is, TIMES CHANGE and we with them.
( Sorry, Mom, i can't recall the Latin saying you taught me.)  "Ham Radio"
as we knew it in the Classic Age of Radio is over, no longer cutting edge.
It's now more of a niche interest. However, even in an age of jet transportation,
sailplanes, homebuilts, and sailboats still exist. There's no reason to really
think radio as a hobby has to die out, altho it is declining, maybe.
I see from the auction prices for shortwave radios that there seems to still
be a high level of interest in them. Probably a lot of this is from us who 
remember when we could hardly think of affording that stuff when it was new.
But i really don't think it's just all old guys.
There's still a lot of fun  & fascinating aspects to radio & electronics. I think 
the issue is the best ways to get these out in the public eye, not in having any 
responsibility to get on the air and yak so the FCC doesn't pull the plug.
My 2 cents.

Subject: GB> Looking over the Knight R-100 (again)

After a while back reading a bunch of negative posts on the Knight
R-100, i picked up a manual for the set. After scrutinizing the manual,
i have to say i am impressed with the design -- at least its electrical
design. Consider:

1 RF stage with a "good" tube, 6BZ6
antenna tune control
separate oscillator and mixer ( altho probably an oscillator buffer
would have been more helpful )
regulated voltage on HF oscillator
2 IF stages
separately operable BFO and Q multiplier ( unlike some sets i can
think of....Lafayette HE-30 and (maybe) a Hammarlund or National)
printed circuit wiring
filter choke in power supply

Now, on the other hand, the 6AZ8 is maybe not the best tube for 
the IF stages.  And why leave a left over triode part unused, when
you could use it for the crystal calibrator?

But, the weak point, as i see it: the mechanics. The dial markings 
look pretty crappy, and it looks like there's a minimal gear reduction
for the tuning. The tuning works look at least in the photo, pretty
much equivalent to the cheapest SW radios. Now, when you put
out a low price kit like this, you cannot afford to have made some
heavy solid castings and gear works, like some military radio or
National, so you have to be a little chintzy. 
I was thinking if this circuit was built into some chassis with the 
robustness of a National product, it would be a real prizewinner,
BUT-- it would easily have cost twice as much, maybe more.

Actually, poring the tube manuals should maybe point out this tube for the

QST even had a kink-type article on using it, as a plug in replacement, back

Subject: GB> 6EH7 vs. 6EJ7 as RF Amplifier

    An earlier posting made mention that the 6EH7 is supposedly a better
choice for an RF amplifier than a 6EJ7.  I evaluated the 6EH7 in my
front-end lineup, and it has a slightly higher ENR than the 6EJ7.  Also, the
linearity is difficult to evaluate as there are no suitable curves to refer
to.  I'm not inclined to use tubes (or transistors, etc.) for which there is
inadequate documentation and only subjective evaluations.

    The 6EJ7 has a higher input capacitance by just 1.0pF, but this is not
of concern as that would be absorbed by the antenna (input) tuned network.

The TS-497 series is the military equivalent of the

I obtained 12 of them back in the 1970s and
reconditioned all 12.  Sold 11 of them off and still
have the 12th.  Works very well.  You just need to use
the 6 dB matching pad so that there are no problems

One thing that has bothered me for a long time, is that as some of you

Those projects undoubtedly have their place. However, few beginners

het.  
It seems to me that after HF transistors appeared, there were a few simple

from any simple construction.
I have saved a few solid state simple projects. I think these are worth 
saving for their rarity, simplicity, and usability:
2-transistor 80 meter receiver, in Electronics Illustrated
2-"                                VFO transmitter, same magazine. NO VFO buffer
chain! No special low pass filter networks!
2-transistor,  line powered ( 120 volt a.c., NO stepdown transformer! )
xtal controlled transmitter, i think also from E.I.
There was also a project for a d/c receiver in one of the ARRL handbooks,
that used something like 3 or 4 JFETs, in a very simple design.

I gotta think that homebrewing and maybe ham radio in general, would be
better off if QST and the other mags had kept up a mix of simple projects
with the more complex, instead of continuously going for the technically
awesome ones. In the same way, why not allow the entry-level class license
to use AM on 10m, instead of SSB, which pretty much locked them into
using an off-the-store-shelf rig? And why not allow the beginners 5  or 
10 watts AM on 160, as is permitted in the U.K. ?  Why not allow a simple

I was thinking that if i had reviewed the radio "back then", i would have to give
it a "10" for value for money. It also occurred to me that maybe there is enuff
room in the set for adding in some kind of better vernier reduction drive. But i
don't need another project. I also wonder how the magazine reviews back then
rated it.
The Knight R-55 has had a lot of negative-trending reviews, more like a toy. I
gather this is mostly a problem of the low selectivity due to the high IF, which
did deal with the image situation. A Q-multiplier at 1650 kHz, either built in or
external, would take care of the selectivity.

Subject: RE: GB> receiver comparison DC vs Regen

I agree with your thoughts Hue. Simple is good. 

I've followed DC receivers since the 50's when I first ran into them. They
are capable of performance rivaling any conventional superheterodyne, if
they are properly designed. Of course, phasing techniques are required to
suppress the "other" sideband. That was pretty expensive and clumsy in the
60's, but it's a lot easier today. 

So, I think, like superhets, DC receivers cover the gamut from the very
simple and effective to the very complex. I don't know why QST hasn't
published more "simple" designs. Perhaps they didn't get any submissions
from authors? 

I do know that, for 'sand-state' Wes Hayward's book, "Solid State Design for
the Radio Amateur" has a wealth of great information about simple DC
receiver designs that really work. 

Maybe today's Ham designers are falling into the trap that many professional
engineers are stumbling into. They have these wonderful and exotic
simulation software (like Spice) so they just keep plugging in parts and
circuits until the device works acceptably. Often the result is a very
complex circuit. But if you're having an automated machine burn and stuff
the board, who cares about a few cents of parts when it saves hours of
engineering time? 

The "art" of building simple takes a back seat to economics in that
scenario, but it's in the art of building simple where many of us find the
beauty in a design, sand-state or hollow-state.

 Hi Chris,
 I just dug out my RCA receiving tube manual to confirm that the 6EH7
is a semi-remote cutoff pentode, while the 6EJ7 is the sharp cutoff version. Thus, if one wished to gain control the RF stage, in question,
by altering the grid bias, on the amp. stage, the 6EH7 does offer an advantage.
 I noticed that the 6KT6 may be a worthy candidate, for consideration,
as even though it's a semi-remote cutoff bottle, has a rated transconductance of 18,000 micromhos, vs 15k, for the 6EJ7, and 12.5K, for the 6EH7.

I have my novice R-100 still, it might not have been too much , but back
then I thought it was great. I got it from a friend who built kits for a
hobby, did a great job. Recently I got it out, put a 3 wire cord on it and
relived those days. It sure does need a better dial drive mechanism, I think
I have to hold the knobs in to get it to turn. I have  a manual from a

This afternoon I was looking up at my beam, a KLM KT-34, and wished I could
get a dipole up at its 55 foot height.

The beam has a 20 foot boom.  As I recall the boom material is 3 inch
diameter.  I also recall that thick elements can be shorter.  However, I
doubt I could get the boom to work on a frequency lower than 15 meters.
Since I already have a four element beam for that band, it would not make
much sense to rig up the boom with a gamma match and turn it into a rotatable
dipole for 15 meters.

What I really need is a 40 meter rotatable dipole up at 55 feet.  Then why
stop there?  Use a delta match, feed it with open wire line, use an antenna
tuner and end up with a multiband rotatable dipole to cover 30 meters as
well.

Trouble is, 20 feet of radiator is probably not going to do well on 40
meters.  I could add loading coils to the ends, extensions to the boom (maybe
a couple of ten foot whips off each end), some capacity hats might come in
handy too.  It is probably going to take one heck of a pair of loading coils
to do any good at the existing boom ends.

Hmm... half wave on 30 meters is only a little more than 45 feet.  20 feet of
thick boom along with 10 feet of whip at each end might just get me into the
ballpark for 30 meters.

The question is, have any of you seen this done, or done it?

Subject: Re: GB> antenna question

Hi Frank:
There has been material on this on the Tower Talk reflector.
Short answer is that it is feasible to run the boom of a beam as a dipole
for a lower frequency.
A complicating factor is the influence of the beam elements.
I understand that the KLM has elements insulated from the boom which
simplifiies things.
I would not recommend the Gamma Match, but others will diagree.
As a first fix:
Take a wire to each end of the boom, raise it a few feet above or below the
boom.
You now have the boom configured as a folded dipole.
Split the new wire at its centre and grid dip it.
You now know the natural resonance of the boom.
It will likely be much higher than 10/7 mHz.
Options:
1. Make light extensions at each end of the boom to resonate on one band or
the other.
Measure the impedance at the feedpoint (see above) and make broadband
transformer to match, or make mini antenna tuner to match. New coax to tx.
2. As above, but add loading coils or helically wind wire on fibreglass fish
poles if you want to reduce wingspan.
3. For two band operation: Make two slightly veed extensions at each end
adjust loding coils so they resonate on 7 and 10. or:
4. Make new dipole above to resonate between 7/10 (around 8.6 mHz good
choice). At feedpoint connect a variable L and a variable C, fiddle the L to
get on 7, the C to hit 10. Feed via 450 line and ATU at TX, or link couple
to L and fiddle with series C in link to get best match on the preferred
band, use coax and ATU (line flattener) at TX to match the other band.

Yes, I have seen it done. W7GKF, Bill Waters, when he lived in Missoula, 
Montana did this with a multi-element (5 elements on 20, IIRC) quad up 
about 100 feet.  This was about 40 years ago.

I think his was built using ideas from an article in either QST or Ham Radio 
entitled "The Long-tailed Quad". I remember the "tails" on each end.

As I remember it, it took him MANY days of tweaking and tuning before he 
got the thing to work correctly on all bands.

Bill is still an active ham and lives in California now. He was a chemistry 
professor and had one of the most delightful senses of humor I had ever 
seen.

He also loved CW, and can still be heard once in a while on 40 meters 
operating CW mobile.

I am sure that if he were asked, he would be most eager to help.

I'll see if I can get hold of him. I really should talk with him anyway.

This is of course, the reason the QST article suggested the 6EH7 for RF amp use and the
6EJ7 for mixer use. It worked very well as a preamp for my receiver. It occurred to me
recently that it might be fun to use this for the amplifying device in an active antenna.

Now here's something that puzzles me: years ago i was given an unwanted TV antenna
distribution amp. It had several 6EJ7's in it, if i now recall correctly, which surprised and
puzzled me at the time, and still does, as the -EJ7 is the sharp cutoff one.

BTW, didn't the Mackay 3010 receiver use a frame grid pentode as the RF amp?

It's 0748Z March 22.

I am on 7.039 and hearing the wierdest signal. it repeats a K 5 times,
then a V, then 5 K's and a V. The interspersed V's follow some pattern,
and for a while will only have 4 K's in between. I listened for a while
and found some intervals of 7 and 6 k's.

OH! now it is a D instead of the V. There was a B also. I have been
listening for 8 minutes now. This is making me crazy. I am tuning away to
see if I can find Alaska or Hawaii, which is why I came down here in the
first place.

Goes on and on, very weak at my qth.

Looks like I just found my first antenna project of the season.

The folded dipole scheme seems the way to go and I can still leave the boom
grounded to the mast at the center.

I already use the mast and beam as a shunt loaded vertical on 75 meters.  If I
can get the boom to work, even if only on 30meters, I will be happy.  Then I can
continue to use the delta loop on 40 meters and probably take down my all band
inverted-vee.

I will probably go with open wire line and use a tuner.  Or maybe use window
line to ease the twist in the feedline while rotating the beam.  Six bands plus
on a single mast and beam.  A fairly clean installation that does not look like
a rats nest of wire.  I should have done this a long time ago.

Frank Kamp

Subject: Re: GB> Strange signal on 40

There are all sorts of these signals on various
frequencies ranging from amateur to commercial to
wherever.  They are generally thought to be some sort
of "spook" ("spy"), but that may, or may not, be the
actual purpose of their existance.

The 30 meter band usually has a number of these in
operation at any one time.

Frankly, they are a "fact of life" and most amateur
radio operators just ignore them.  Sometimes, if you
transmit near their frequency they will move and
sometimes not.  Many of these seem to be completely
automated (not just automatic transmissions) and move
from frequency to frequency on a predetermined
schedule.

Subject: GB> The "Cutting Edge"

Back, fresh after giving a double concert fri & sat.  Home
on Sunday, and the ol mail box is jammed and i am still
going thru it.

First i wanted to say Yo!  Vincent motorcyles!  What i wouldn't
give even for the Pre Vincent HRDs.

Now, off to other old technologies and the looming demise
of Ham Radio.  Hue's comments got me to thinking, especially
the phrase "cutting edge", and i agree, ham radio in the classic
sense is really no longer squarely on the cutting edge, and 
the "niche" factor is firmly entrenched.  And yet . . . . 

I had a chat with a welcome visitor, Hiram, just  the other day.  
Between false lights of "the ol' pipe" and fatherly reminiscences 
of other "young squirts" like me who have "ideas without handles",
he said something i have not quite forgotten.  Hiram does not ken
the use of such phrases as "cutting edge", so may i take the
liberty of paraphasing for him?  I know he would hate that.
Sorry, Mr. H. . . .

"Cutting Edge" is where you find it.  And usually you find it
where you last put it. "

I'm a big one for moaning that all the excitement already 
happened.  I call it "George Eastman Syndrome".  George
gave us acetate film and the first "everyman's" camera.
George founded the largest camera operation on earth, 
Kodak.

He put a bullet in his own head because, as he wrote,
there just were no more challenges to take on!  He just
could not see beyond his own proboscis.

I read about how Ham Radio lost that pioneer "frontier" ( hmm,
sounds like cutting edge to me ) in the QST's "Correspondence
from Members" of the early 1960s.  All the while this little guy
called "Oscar" was bleeping "HI" all over the ether.  Ironic.

I remember moaning about how i wish i was born around 1900,
so i could get in on the ground floor.  Hiram would say "ground
floor of what?  Squirt, we're ALWAYS on the ground floor! " 

I bemoaned the reduction of tube use while 73 and CQ magazing
was spitting out some of the first BASIC algorithms written by
hams to replace the old satelite tracking protractors, animations
on 286 DOS systems that would not only compute but animate
video representations of apogee and perigee.  Slow scan
was shifting over from the Robot 48 line scans on phosphor tubes
to VDTs.  I wasn't looking, i was busy wishing i was on the cutting
edge when Grammar and Lamb was busting loose with innovations.
While i was wishing i had an old Klineschmidt, Ascii communication
modes, Packet Radio, PSK was "happening"  Aww, but it wasn't
the same thing, i complained. "That stuff all comes from the
engineers and the military and Nasa these days, the days
of kitchen table 'cutting edge' is finito.  Done.  Over!"

"Cutting Edge, Hmphh!" snorted The Old Man as he re-lit the last
embers of his cavendish.  "Seems to me you have so many cutting
edges you need to carry a styptic pencil! "  I noticed that he had
a 1999 ARRL Handbook face down in his lap, opened right about
where Digital Signal Processing was being explained.  

"Hiram, that's not very cutting edge these days, either." i said,
sounding like Rocky the Squirrel.

"Son, you don't understand what a "frontier" is.  Our forefathers
were not pioneers because each one necessarily hacked the furthest
tree in the woods, or put up the outermost stockade.  They were
pioneers because they chose to live in that place. "-- and well he
knows, his own lineage looks to the Mayflower for arrival --
"Hams are not pioneers because they necessarily push back
the frontiers, either.  But they choose to dwell there. They take
it in their own hands and do with it as propriety and necessity
demands!  They can be called 'pioneers' because they choose
to live there.  And don't you think MacMillan was every bit the
pioneer "cutting edge" character with all his newfangled radios
and airdrops and electric generators and medicines when he
bit into the frozen arctic with "QP" as any Mayflower passenger
or spanish swashbuckler?  "  

Hiram sat back in my easy chair once more and looked at the
crown molding above the entertainment center in my living room.
I think he was looking at something far more distant.

" I made an electric car once.  In fact i was responsible for
quite a few of 'em around Hartford.  They call me an automotive
pioneer, but son, i didn't invent them!  In fact, i didn't really do 
much in the way of developing them.  But i did *traffic* in them."

- he waited for a laugh and got rolled eyes instead.-

"I DID race 'em, i might add!  Way before traffic lights!"

"You have a bunch of undone projects out there in that catastrophe
you call a radio "shack"!  Much as i wish you'd finish them, i
admire the fact that you boys are lighting the old torch and
melting solder. Sure, you might be using circuits ages old, but
you ARE USING them, innovatively, using the ol' noggin.  Learning
new ways to apply them.  Improving on the mistakes of us ol'
"pioneers".  Your work with our "old ideas" make them worthwhile.
Never forget that.  It's not the 'inventor' that creates the so-called
'cutting edge', but those who give those inventions feet and hands".

The Old Man went back a'staring a hole in that crown moulding.

The frontier, the cutting edge is where you find it.  And you
find it usually at the intersection of Passion and Talent.
And you never know just where the next "Cutting Edge" might
crop up.  From what Hiram says, you might be on one . . .  
. . . right now!    Carry that styptic pencil.

So join me, with Hiram, in our optimism regarding not only
ham radion, but it's traditions, but also it's relevance.  Cutting
edges are still to be found, i am very sure.

We have been getting more reports from AK than anywhere else in the USofA
and some people in Central Europe have reported hearing some of the

result of this authors typing skills and will be corrected and posted

Subject: RE: GB> The "Cutting Edge"

About 25 years ago, a guy I knew decided to get out of his motorcycles. Among others, he had a gorgeous original Vincent in ride-able condition and the big Arial (sp?) square four that looked great but had engine trouble (those rear cylinders never got enough cooling...). I could have owned them both for $1,500. But I was recently married and headed off to grad school and could not swing it. Egad...

Other deals I missed: When I lived in Miami in 1974, the local cycle shop mechanic guru offered me two 196? Marusho Japanese BMW copies in great condition for $500. But I was broke... Later, in Georgia, one of my best friends who hardly ever got out riding was selling his Laverda 750 for just $500. It was perfect and original and had 2,400 miles on it. But I was still broke... He later traded it in on a Moto Guzzi and was killed driving the Guzzi. If I'd have had a little more money I could have saved his life. He died in intensive care exactly one month to the day after his wedding day. I have never experienced anything as devastating as that before or since. Shortly thereafter I got out of motorcycles for good.

pioneer "cutting edge" character with all his newfangled radios
and airdrops and electric generators and medicines when he
bit into the frozen arctic with "QP" as any Mayflower passenger
or spanish swashbuckler?  "  

Hiram sat back in my easy chair once more and looked at the
crown molding above the entertainment center in my living room.
I think he was looking at something far more distant.

" I made an electric car once.  In fact i was responsible for
quite a few of 'em around Hartford.  They call me an automotive
pioneer, but son, i didn't invent them!  In fact, i didn't really do 
much in the way of developing them.  But i did *traffic* in them."

- he waited for a laugh and got rolled eyes instead.-

"I DID race 'em, i might add!  Way before traffic lights!"

"You have a bunch of undone projects out there in that catastrophe
you call a radio "shack"!  Much as i wish you'd finish them, i
admire the fact that you boys are lighting the old torch and
melting solder. Sure, you might be using circuits ages old, but
you ARE USING them, innovatively, using the ol' noggin.  Learning
new ways to apply them.  Improving on the mistakes of us ol'
"pioneers".  Your work with our "old ideas" make them worthwhile.
Never forget that.  It's not the 'inventor' that creates the so-called
'cutting edge', but those who give those inventions feet and hands".

The Old Man went back a'staring a hole in that crown moulding.

The frontier, the cutting edge is where you find it.  And you
find it usually at the intersection of Passion and Talent.
And you never know just where the next "Cutting Edge" might
crop up.  From what Hiram says, you might be on one . . .  
. . . right now!    Carry that styptic pencil.

So join me, with Hiram, in our optimism regarding not only
ham radion, but it's traditions, but also it's relevance.  Cutting
edges are still to be found, i am very sure.

Tnx for the info Ray. I hear them too from time to time and assumed they
were some sort of beacon. Must be running some serious power - the K beacon
is often audible in N.W. Oregon even in the daytime. I'm hearing it about S3
right now at 1623Z

There was an article on doing just that in QST between 1968 and 1975. (I'll look it up when I get home). 

The author had a 4 element quad (!). He extended the boom and added loading coils, IIRC. Found that the quad elements acted as capacity hats so he didn't need 70 feet for 40 meters.

He used a gamma match and got a decent SWR. How he installed the whole thing without a bucket truck is another matter!

If you have a 20 foot boom and you put 8 foot extensions on each end, there's 36 feet, which is a little ove half-size for 40. With the loading coils more than halfway out from the center, the whole thing may be manageable.

Good luck!

Thanks for that Ray. I printed your email.

I kept wondering last night about the U and the D I was copying. The signal
was really weak with QSB. So the U might have been a V missing a dit and
the D might have been the last element of the previous K with the first 2
elements of the V. It was the kind of signal that I have to close my eyes
and listen carefully. I was not using the headphones either. That would
have made it better.

Anyway, thanks a lot and now I will know what's up next time. I can't hear
anything there right now with my crummy antenna here at work and my R-2000
at 1740Z.

Subject: GB> Kenyon T-26

On the weekend AM round table, yesterday ( 7160 14:00 CST ) there
was discussed the need for driver transformers to drive modulator
tubes... Seems the folks have salvaged plenty of big iron plate
modulation transformers, but let the smaller interstage transformers
go the recycler's... Seems that  push pull driver plate(s) to push pull
 grids is a highly desirable configuration...

I have a Kenyon T-26 unit that appears to be an interstage xfmr, maybe
even a driver for the grids of a pair of 810's...

Searching the I-net gave no info, so if I may ask the group, does anyone
have any info on this xfmr... One thing I notice is that some of the
many terminals are marked with letters, and others are marked with
numbers... I don't remember ever seeing a transformer with this terminal
designation...

Thanks,

    Ah, that gives me something to work with.  I downloaded the datasheets
for both of these from:

and found the same curves for both tubes, which is exactly what I needed.

    It looks as though the EF184 is the European equivalent of the 6EJ7.

Ah, but they do on occasion issue a data transmission.
They are more for channel marker than radio location
as there are a lot of Russian (I keep wanting to say Soviet)
nets that operate in and around the 40m band and
they can provide a frequency for the net to come up 
on, but more likely they use it for propagation to know
when to make best contact in the region.  Last I heard
they were still way behind in the telephone technology
where it would put radio out to pasture.  If one looks
at a lot of these locations, they are either on the Volga
or along the Trans-Siberian railway where traversing 
that territory is essential to have a means of communications.
I have not heard the data transmissions but it has been
reported on the WUN list in years past.  Also, these
beacons can be reckoned on by the aircraft when they
have artic manuevers.  From October to April, the
43rd, 50th and 5th Air Armies have artic war games,
money allowing, so that is another use for the beacons.

It should be noted that besides 7039, these are also transmitting
in various shortwave ranges including the 80m and other 
amateur bands, have been heard in the 5,6,8,10, 14 and 
a number of other ranges.  As Glen pointed out, they may also
be used by traveling agents to check the propagation between
the homeland and various targeted locations.  By the
way, that is also a usage of the voice and cw 5number/5letter
group broadcasts often heard on the 30m band 10.125 
(enigma 208 I think the lable is), where there may be no valid
traffic but hearability studies.  

It is an interesting field.

I almost forgot to mention, it does not take 
a continuous signal to obtain a bearing with
the equipment of recent years.  Before I 
retired we were using an older 2 channel 
interferrometer (7 antennas) and a bearing
could be obtained within a few seconds, 
the FCC system using the automated system 
they have now, can do a fix within 25-50 miles
in a few seconds - basically one transmission
if the frequency is already acquired, but for sure
within a couple of transmissions.  The larger
interferrometer systems or single site locators
can do the same on one transmission.  Allowing
for older technology such as the old Aeroflot
KRUG in Russia, it might take 3 or 4 transmissions
but doable without continuous tone or transmission.

Thanks for the ideas.  I would like to see that article.

My tower is a hybrid tilt-over.  I have about 20 feet of Rohn tower that is topped with a steel plate.  The plate has a hinge mechanism welded to the top.  Then I have a combination 3 inch and 2-1/2 inch drill stem that is 53
feet long.  It is hinged at the 20 foot level.  I use a boat winch to lower the beam onto the garage roof where I can work on it.  It is a little better than having to climb a tower.

Right now I am leaning toward linear loading.  Shooting for something less than 40 feet total length.  I will probably scale it down to 10 meters and try it before I start working on a 40 meter version for the beam.

I also found a very neat linear loaded, 40 meter dipole project at:

Subject: Re: GB> 6EH7 vs. 6EJ7 as RF Amplifier

    Using the datasheets for the EF183/6EH7:

    http://www.mif.pg.gda.pl/homepages/frank/sheets/010/e/EF183.pdf

and for the EF184/6EJ7:

    http://www.mif.pg.gda.pl/homepages/frank/sheets/010/e/EF184.pdf

I was able to do anevaluation of these two tubes for use as an RF amplifier
stage.  Here's the vital statistics:

    TUBE    EF183/6EH7    EF184/6EJ7

    gm       12.5mA/V      15.6mA/V
    Ri       500K          380K
    Ci       9.5pF         10pF
    Co       3pF           3pF
    Vp       200V          200V
    Ip       12mA          10mA
    Vg2      90V           200V
    Ig2      4.5mA         4.1mA
    ENR      490 ohms      300 ohms
    Curves   p.3           p.4

    These tubes appear to be fairly similar until you get down to the last
two entries, and here we find that the 6EJ7 is significantly quieter than
the 6EH7 (490 vs. 300 ohms ENR).

    In looking at the transfer curves in the two datasheets, we find that
not only is the 6EJ7 noticably more linear than the 6EH7, but the variation
of the transconductance with the control grid is much smoother, rendering
the 6EJ7 more forgiving at AGC extremes and less likely to cause AGC
motorboating.

    Now that I have datasheets available to do an "apples vs. apples"
comparison, I would choose the 6EJ7 ahead of the 6EH7.

Certainly is. The 183 and the 184  were widely used in TV sets and there
have been a number of amateur rx projects published using them-one that
comes to mind was the Electronics Australia (then RTV&H) version of the
Wadley loop front end-the Deltahet- published in mid-1963. It used both-a
6EH7 as RF amp and a 6EJ7 as second mixer (They used a 12AT7 as first mixer)
with a pair of 6EJ7s as the 37.5MHz  amp.
 But I'm sure both were widely used in all sorts of amateur applications- I
even had an EF184 at the start of  the multiplier chain in an xtal
controlled 2 MX transmitter at one time.
 There was a post script to the QST article as well- original article was in
Feb 1966 and a postscript from F8AJ in QST for July 66. I only have a very
poor xerox of the latter though.

Well that is normally true, especially with fixed
sites normally configured.  and then the fix 
information is tightened up with mobile units to
get it within the 25-50 mile eliptical area.  However,
with a single site locator, one can get to the same
eliptically patterned area with just one site, but
the accuracy is enhanced with an ionospheric sounder
or series of sounders set out 1000-2000 miles in
the directions of interest.  In other words, one could
have 4 sounders at the main direction points of N/E/S/W
and get a relatively good position that could then be
followed up with mobile units.  These sounders you
have probably heard on the ham bands as they pass
thru, going up or down in frequency - sounds like
a sweeper - which it is, usually sending out the signal
from a broadband omni antenna (crossed dipoles)
and will run the range set by the computer program -
say 6-25 Mhz and it takes several seconds to run up
stop then run back down.  The transmitter power is
also set at about 10-20 watts - 25 I think is the max.
The incoming signal from a specific area is then 
tabulated in the computer with what the sounder shows
at that frequency, and range with its bounce off the
ionosphere.  They do work very well.  And where
an agency can't, for various reasons, get space to
install the minimum of 3 fixed sites(foreign jurisdiction), 
the single site at just over the cost of a single with the sounders,
can be put to use.  And the sounders can be put in an
office building such as embassy or counseler offices.
Not a lot of detail but hopefully you get the idea.

Ok, now I have an authoratative reference regarding "penning" crystals.

On page 48 of the February 1933 QST, there's an article entitled "Silvering

There's a followup article on page 41 of the March 1934 QST entitled

On page 15 of the April 1935 QST, there's a "Strays" article "W8MJR suggests

I first heard of that trick about 28 years ago, and it definitely wasn't
new back then (It probably dates back to the 1930s, although I don't
have an authoratative reference.).  Back then, American Novices 
were restricted to crystal controlled rigs, and, even then, crystals 
were expensive.  So, if you wanted to change the frequency of a 
crystal, you could open it up (we were all mostly using FT-243 
crystals back then),  pull the rock out, and give it a good rubbing 
with a pencil.  The graphite would load the crystal, pulling the 
frequency lower.  The only problem is that, over a couple of 
weeks, as the crystal shed the graphite, the frequency would 
drift back up toward the original frequency.

That's great Ron, I'll look forward to hearing your further experiments and
perhaps adding details of your results to my webpage.

I can't claim credit for the technique though, I first heard about it in an
article in SPRAT, the journal of the G-QRP club, issue #99, "Penning Down
Crystals" by Richard Wells G0RXH. My webpage is really only a writeup of my
experiences with Richard's technique.

Tying this back to all the other threads too...

Here's a page with the circuit diagram of a 14MHz Franklin oscillator done

Huff and Puff stabiliser for stabilising it (though it's already very

 Dear amigo Chris:
You are absolutely right !
EF184 is the best pentode for RF amplifier duty...
But, let me ask you something... have you thought
about the ECC88 and the even better ECC189 dual
triodes that were designed for TV tuner work, and
that incidentally were also about the last vacuum tubes
ever designed from ""scratch"" until Phillips and other
European manufacturers stopped from making
receiving type vacuum tubes.
The ECC189 is simply wonderful for a front end !!!
I am sure that you are aware of our limitations here at
my QTH regarding the possibility of obtaining solid
state modern devices... so we still make ""new"" ham radio rigs using mostly
vacuum tubes...
We even still make a version of "" The Islander"" a DSB transceiver with
direct conversion vacuum tube receiver...
Tube lineup is
EF184 RF amp
ECH81 product detector
ECH81 triode section not used
ECL82 triode audio preamp
ECL82 pentode audio output
6AH6  VFO ( Russian equivalent 6*5P )
Audio filter provided by good working brain of
operator !!!
Keep up the good work amigo !!!

1952 Vincent Black Lightning

Oh says Red Molly to James "That's a fine motorbike. 
A girl could feel special on any such like" 
Says James to Red Molly "My hat's off to you 
It's a Vincent Black Lightning, 1952. 
And I've seen you at the corners and cafes it seems 
Red hair and black leather, my favourite colour scheme" 
And he pulled her on behind and down to Boxhill they did ride 
Oh says James to Red Molly "Here's a ring for your right hand 
But I'll tell you in earnest I'm a dangerous man. 
For I've fought with the law since I was seventeen, 
I robbed many a man to get my Vincent machine. 
Now I'm 21 years, I might make 22 
And I don't mind dying, but for the love of you. 
And if fate should break my stride 
Then I'll give you my Vincent to ride" 

"Come down, come down, Red Molly" called Sergeant McRae 
"For they've taken young James Adie for armed robbery. 
Shotgun blast hit his chest, left nothing inside. 
Oh come down, Red Molly to his dying bedside" 
When she came to the hospital, there wasn't much left 
He was running out of road, he was running out of breath 
But he smiled to see her cry 
He said "I'll give you my Vincent to ride" 

Says James "In my opinion, there's nothing in this world 
Beats a 52 Vincent and a red headed girl. 
Now Nortons and Indians and Greeves won't do, 
Ah, they don't have a soul like a Vincent 52" 
Oh he reached for her hand and he slipped her the keys 
Said "I've got no further use for these. 
I see angels on Ariels in leather and chrome, 
Swooping down from heaven to carry me home" 
And he gave her one last kiss and died 
And he gave her his Vincent to ride.

That song gives me chills - good chills!  You can hear it a lot on 
WDVX.  WDVX is on the Internet and really worth listening to.

http://www.wdvx.com/
  -or-
http://www.live365.com/stations/wdvx  (Higher Quality sound)

WDVX - 89.9 FM Knoxville, TN.  The studio is in a camp trailer, and the 
station is in East Tennessee.  The programing is first rate and 
refreshing.  They play mostly old country style music and Bluegrass.  I 
first heard "1952 Vincent Black Lightning" on there at least 4 months ago.

Yes, end loading coils are out.  I think the only way they could work is to use
enormous capacity hats which probably would screw up the beam pattern.

I just finished studying an analysis of linear loading at:

http://www.cebik.com/mu/mu4a.html

I also found specifications for a three element 40 meter KLM beam that uses
linear loading.

I have lots of aluminum tubing left over from old beams.  I also have enough
sheet PVC to make insulators, so I will probably try to duplicate the KLM 40
meter design.  Maybe try a 10 meter scaled down version first before I make
parts for the KT-34 and get an unpleasant surprise.

I want to leave the boom grounded at  the center so I am going to have to use
some sort of 'plumbers delight' feed system.  That also eliminates a center
loading coil.  Right now I am considering a T-Match to preserve balance into
open wire line ( or window line ).

Thanks for the comments,

    I looked at the ECC88 (6DJ8) and ECC189 (6ES8) for use in the mixer
stages.  They both have very good calculated amplifier ENR's of 200 ohms,
however the linearity was not very good (the ECC189 got a "poor" rating), so
I traded off a little noise performance for far better linearity by going to
the 6BK7B dual triode.

    In looking at the plate transfer characteristics of the ECC88, I see
that it would have some usage as an AGC stage, but it doesn't have the range
of transconductance as with a pentode.  With the 6BK7B, I see the same
transconductance "knee" that I saw with the EF183, though not as severe.  It
does have a broader transconductance range, which would make it attractive
as an RF amplifier with AGC.

    Having been deeply involved with small signal amplifier and mixer
intermodulation distortion for a number of years, I tend to take the
nonlinearity aspects a bit more seriously than most people.  And in the HF
bands where terrestrial and galactic background noise are limiting factors,
I can afford to give up a little in terms of noise performance if I can
realize a significant improvement in distortion characteristics.  I can make
up some of the difference by being mindful of the equivalent noise
temperature of the antenna.  I would lean towards NF performance as I get
into VHF frequencies.

    You may be at an advantage using tubes.  They are more forgiving, have
better dynamic range, and you already know that they've stopped making most
of them.  I have been caught too many times with having state-of-the-art
solid-state devices turn into vapourware overnight.

    As a result of this ongoing discussion, I dropped in on a local
high-tech junk yard this morning, looking to see if they had the tubes that
I was interested in.  As I was leaving, I happened to notice an item
sticking out of a rack full of test equipment.  I reached over and pulled
out a GR874-LTL trombone line, complete with GR874 to BNC adapters.  Beneath
it was a second one.  Bought the pair for just $40 each.  They normally sell
for as much as $400-$500 if you can find them.  One was frozen due to the
lubricant drying out, but it works now after working some penetrating oil
into it and then giving it a lube job.  Funny, as I was in dire need of a
phase shifter, and these are beyond what I had in mind.  Just a lucky find,
that's all.

Besides having a gM of 8250 umhos at 180 plate volts, I'll leave electrical 
comment to others.

But note this:

Unlike most miniature twin triodes, the 5687 has the 9H pinout. (The 7044 and 
2C51 have similar basing arrangments). This unusual basing allows a very 
symmetrical layout in push-pull and balanced circuits, and also in grounded-grid 
applications with both sections tied together.

9H base:

1 and 9 are the plates
2 and 7 are the grids
3 and 6 are the cathodes
4 and 5 are the heater
6 is the heater midtap.

Did it ever.

One of these, cut down to a lower profile from it's too-tall $5
antecedent, is my bench receiver.

A witheringly strong signal won't confuse you with it's image, despite no
RF stage, with a 1.650 mc IF.  And the hit-or-miss dial calibration is
unimportant to a pragmatist.  It's much easier to make up a list of where
the MCs are than try to align it to someone's get-it-out-the-door
approximate.

Moreover, if one turns the R-55 to standby, the 1.65 IF is accessible as
a Q-5er for legions of 6M and other high IF devices.  That allows you to
hear 50.110 SSBers on a LaFayette HE-45 if you can stay with the drifts.

So don't count out the Knightkit R-55, round corner or square.  It's the
pick up truck of radio.  And it's chassis, bendable is it is, would be
open with Octals.  With miniatures, it can be soldered with a pistol grip
Weller.  I think mine was.

I've been trying to talk local Atlanta bud and Honolulu bud who's from
China into a Shanghai to Paris ride on old style bikes. Fly to Shanghai,
acquire bikes, spares, whiskey, cigarettes, 'etc' and off to Paris.  They
are slowly warming to the idea. Biggest problem is logistics. I'm the 'to
hell with it, damn the planning, what's logistics got to do with it' guy.
Maybe when they get a little more 'age' on them they'll come around. With
three guys and three bikes, the system has plenty of redundancy :-)

Subject: GB> ICXs and other crystal trickery

W4BWS reminds me of the International Crystal converters FCV-1 and FCV-2.

Both are usually seen without tubes or xtal in the "make offer" boxes. 
They are distinguishable for having their names on the boards and either
is fine for 6M.  In fact, the FCV-1 only worked on 6--down to 40M or BCB.

A 6AK5 is adequate on 50mc and in the FCV-1 it drove a 6J6 mixer.  The
FCV-2 was available for 6 or 2M and used a 6BQ7 twin triode in Wallman
Cascode before a 6U8.

Find one but no xtal?  Try this side-of-the-road expedients:

An IBM AT board crystal, 14.318, triples to put 50 mc at 7.046 on your
40m dial.  That gives coverage from the beacon part of 6 up thru about
50.250 which is as high as the ayatollahs want you to go anyway.  Will it
work in an International Crystal converter?  Don't know.  I'm about to
try it on an Ameco from Eric Jones, however.

Rather have 12 Meters? 

I note a tv colorburst crystal, the 3.578 thing loved by 80M minimalists,
counts up to 17.900 on 5th harmonic.  That should put 12 meters down to
your 40M rig in just about any 10m converter you find or build.

Subject: GB> antenna question

Thanks to all for the helpful input.  I now have a plan that might work
in turning my KT-34 boom into a rotatable 40 meter dipole.

I also have another question.

I have always heard that loop antennas are quiet when compared to an
ordinary dipole.  Less static, more signal.  I have never given that
much thought and always thought the claim made sense because it is a
closed loop of wire.

However, it is not a closed loop of wire.  It is cut to insert the
feedline.  The loop is not even at DC ground unless driven by coaxial
cable with grounded shield.  So why should it be less likely to build up
static than an ordinary dipole?  In fact, the loop has about twice the
amount of wire of an ordinary dipole.  Wouldn't that additional wire
pick up even more static?

My right angle 40 meter full wave loop is probably the noisiest antenna
I have but  works great.  Now I am wondering if I am doing something
wrong.  Is there some trick I have missed that would improve its signal
to noise ratio?

Regards,
Frank Kamp

This is truly too much of a coincidence, Barry!  Today I am shipping off a
nice Knight V-44 VFO to Jim, WB8REH.  He is putting it with his T-60/R-55
pair that he just acquired last week.  I'm not sure where he got the Tx/Rx,
but he found the VFO on my site after doing a google search.

He tells me he's been off of HF for 12 years, and that this is his first
"boatanchor station."

Apparently he got the R-55A fired up yesterday.  Here's his comments:
"I did get the R55a aligned and cleaned up and going.  It looks to have all
the
original tubes in it as they say Knight-Kit on them.  It is a wide as a
barn--
you don't need to tune it, you just have an all-frequency at-all times
receiver
hi hi. It makes you appreciate the new receivers, but just the look, size,
sound and smell make it worth the time."

I passed along the suggestion that a MFJ CWF-2 would probably be a cheap way
of making a real CW receiver out of it.  Any thoughts?

Tom

Subject: Re: GB> antenna question

I discovered something interesting two days ago.  I run a Collins S-Line 
on 40 meters.  I sat down to the rig for my nightly dose of OMISS Net 
and found that there was almost NO QRN.  I had to advance the audio gain 
about half dial (normally I use only about 1/4 dial) to hear the level 
of noise I was used to on a normal evening on 40.  BUT...the signals 
were almost normal, a bit muted, but not as muted as the noise.  I tried 
for 15 minutes to check into the net and no one could hear me so I gave 
up.  Now, normally, I dont have any problem getting checked in so I gave 
up knowing something was wrong.  The SWR meter showed that I was putting 
out 130 watts and reflecting only 18 so it seemed that the antenna was 
OK, right??  NO, all was not right with the antenna.  I went into the 
attic and found the center connector of my RG58 run, where it connects 
to the 450 ohm twin lead (which is 55 feet long and feeds the hot side 
to a 96' Inverted "L" and the ground side to the sprinkler system), was 
broken.  The only antenna I had was the ground side which goes to the 
sprinkler system in the yard.  The RG58 has a string of ferrite beads 
over the outside where it connects to the twinlead so that it will act 
as a Balun and apparently that was why there was not much reflected 
power and the transmitted power must have been just dribbling out the 
end of the wire into a puddle of electrons on the attic floor because it 
sure wasn't radiating.

But what I learned from this was that maybe the sprinkler system makes a 
good RECEIVING antenna.  Maybe I should rig a separate transmitting 
antenna and use the sprinkler system for receiving.

This is somewhat like the old trick, counter-intuitive antenna question that goes something like: 

True or False: The ground is an effective RF radiator. 

The correct answer is True. But don't ask me to explain it...

Subject: Re: GB> antenna question


I discovered something interesting two days ago.  I run a Collins S-Line 
on 40 meters.  I sat down to the rig for my nightly dose of OMISS Net 
and found that there was almost NO QRN.  I had to advance the audio gain 
about half dial (normally I use only about 1/4 dial) to hear the level 
of noise I was used to on a normal evening on 40.  BUT...the signals 
were almost normal, a bit muted, but not as muted as the noise.  I tried 
for 15 minutes to check into the net and no one could hear me so I gave 
up.  Now, normally, I dont have any problem getting checked in so I gave 
up knowing something was wrong.  The SWR meter showed that I was putting 
out 130 watts and reflecting only 18 so it seemed that the antenna was 
OK, right??  NO, all was not right with the antenna.  I went into the 
attic and found the center connector of my RG58 run, where it connects 
to the 450 ohm twin lead (which is 55 feet long and feeds the hot side 
to a 96' Inverted "L" and the ground side to the sprinkler system), was 
broken.  The only antenna I had was the ground side which goes to the 
sprinkler system in the yard.  The RG58 has a string of ferrite beads 
over the outside where it connects to the twinlead so that it will act 
as a Balun and apparently that was why there was not much reflected 
power and the transmitted power must have been just dribbling out the 
end of the wire into a puddle of electrons on the attic floor because it 
sure wasn't radiating.

But what I learned from this was that maybe the sprinkler system makes a 
good RECEIVING antenna.  Maybe I should rig a separate transmitting 
antenna and use the sprinkler system for receiving.

Gary,

Of course, from about 1956 thru 1962, Royal Enfield Motorcycles in the US were known as "Indian Motorcycles." These pictures sure bring back a lot of memories though. I owned an Indian Apache back then, which had a 700cc vertical twin motor while the popular Triumphs and BSAs were 650cc. Thanks for sharing.

  Someone once told me they don't make anything 
  like they used to.  This is a bit off topic ( what else 
  is new? ) but might be interesting for you traditionalists 
  out there, especially those who like to dink with old 
  technologies, radios, sailboats, steam engines and 
  black powder.  Add my personal favourite, British bikes. 

  Google up "Royal Enfield" and check out those 
  machines.  Straightway out of the 1950s and 60s, 
  and these are not replicas!  No sir, these are their 
  regular production bikes.  Nowadays they are made 
  out of Delhi, India instead of their native Birmingham, 
  but are nonetheless reclaiming their share of brit- 
  bike devotees. This year they had a race team at 
  Daytona, which i call "Hog Heaven" during bike-week. 
  And . . .  the Enfield cost under  � 4000, a far, far, 
  far cry from Norton and Harley !!   
  ( a Bullet Clubman is under 5000 dollars US! ) 

  Of course here, near Daytona, it's hard to find 
  many folks with the proper taste to apprehend 
  the finer Vincents, HRDs and other British treasures.

  Take a peek at

  Check out the military Bullet at the bottom, too.  It's the real item. 

  So, sailing, motorrads and valve radios!  The retro- 
  action is growing!

My first nonhomebrew SW rx was an AR-2. Basically a transformer-power-supply AA5 with BFO:

12BE6 converter
12BA6 IF
12AV6 det/audio/AVC/ANL
12AV6(?) BFO
12A6 audio
5Y3 rect.

No calibrated bandspread. No antenna trimmer. No VR, S meter, RF amp, xtal filter. But waddya want for $20 used?

The AR-3 eliminated the separate BFO but added an antenna trimmer.

Anybody ever see an AR-1? Amazingly basic - didn't even have bandspread, BFO or RF gain control. Article in QST about 1953 showed how to add those things and wind up with a basic rx. 

But any Command set rx would blow them all away. As would a well-built regen.

I wish I'd known the xtal converter/BC-453 trick back then.....

I have made several adapters by using a 7 or 9 pin socket and soldering 
solid wire to the pins. The wires pass thru a pwb/fiberglass piece with 
the 7 or 9 pin pattern drilled and these form new pins to go into the old
socket. It also works to put a 7 or 9 pin mini tube into a octal socket
for
upgrades. The spacer is drilled for the 8 pins of course.  I also made a 
mod for replacing the 6SK7 rf amps with a cascode 6BQ7 by using a 
recycled 2E26 metal base and running wires from the 9 pin socket pins 
into the octal socket pins from which I had removed the solder. I then 
soldered the octal pins and the ears of the 9 pin socket to the metal
shell
of the octal plug. This made a very rugged plug-in adapter and a really 
hot front end.

Just got my first order in from justradios. Got a bunch of Orange Drops and

1. They have a nice collection of capacitors in common values. If you want
you can save a few bucks by ordering a "kit" of a one type of caps. I just
made up a list of what I need to restore the next 3-4 radios.

2. They make it easy to figure your order because you can download an active
Excel sheet. It keeps track of all your sub-totals, total, discounts, etc.

3. Their shipping is very reasonable @ $3.90 surface or $4.90 for airmail.

4. 10% off any order over $50.00 (I purposely made it so my order came out
over $50.00)

5. Email order form, pay via PayPal. Confirmation next morning via email.

6. Order arrived quickly. Packaged very nice in a small box with the
different cap values separated into tiny Ziploc baggies. They threw in a few
pieces of tubing as a small bonus.

Usual disclaimer: I don't have anything to do with this company except being
a satisfied customer. Their prices are very reasonable and their service is
excellent.

Subject: GB> T-12 buried with Wouf Hong?

Consider if you will the International Crystal T-12 transmitter.  This
modest MOPA, reviewed in QST for December, 1957 at page 33 and offered
for sale on page 114, was in time for Christmas.  And we know at least
some of them got out the door, and probably in to TV sets as there were
some 21 mc IF TVs left in '57 and the T-12 would work 80, or 40 "straight
through" as the ads claimed.

And the next year, when CB came, International Crystal was in with both
feet.  So it's not hard to understand why they didn't keep making a
3.5x6x3.25 open board TX requiring B plus and filament "not supplied" for
its 12BY7 and 5763.  You had to buy a crystal too, for $3.  The T-12 was
$9 kit or $14 assembled.

But did they all fall into the twilight zone of technology as Sputnik
passed over?

Back in '98 I beat the drum for even one, or a piece of one, and failed. 
We tried to infer the diagram from the picture of the board and I've kept
Dave Newkirk's speculations.  But still no archeological evidence.

So why not look in the basement, the attic, and the "make offer" box at
this season's hamfests for anything that says "International, Okla City,
T-12" or has the memory of a miniductor on one end next to two Mica
trimmers?  On the foil side it says "ICM T-12," or the picture does.

Anything would do.  If I can get the schematic, even, I can work from
there.  And It's not too far from Dallas to Oklahoma City, at least on
the roads, and I could take it into ICX and shout, "See?  You LIED!"

Our pals in Oklahoma City don't like to be reminded of their CB past,
their STP-50 6M TX that doubled in the final, or that attorney's dream:
the unshielded T-12 with a little pin for "350 VDC."

I'll put one on the air, or a replica, if we can find one and be happy to
make schedules.  (All my neighbors have cable to get the Spanish soap
operas)

Found an interesting early VHF piece the other day. It's a Bliley CCO.
Uses 6AG7 as active component to run xtals at up to 60Mc or so. Two freq

Anyone know of any published projects employing this little module?

Brad,

These headers are commonly installed in tin- plated steel cases for use in
hermetically sealed relays and transformers.  It might take a little less
heat to solder one in a steel housing than in a copper housing, but not
much.  The secret is to put the items to be soldered on a common hotplate
that has a flat top with a pebble finish surface and bring everything up to
a temperature of 200 degrees F or so (more if you and / or the hotplate can
stand it).  Then use a 40 or 50 watt iron with a hefty chisel tip and a
decent non-corroxsive flux to solder the header in place.

Using a thinner-walled copper tube might be a better choice. I know of
one online source that sells small quantities at reasonable prices. I
imagine there are at least several others.

Thin walled brass tubing is available at the hardware store here but it is 
not inexpensive. I hoping to run across a trove of unassembled cans as 
coming from some manufacturer's surplus, for example. It had been suggested 
to me that spice tins might be something to consider.

I hadn't tried preheating, per se, but the headers definitely take solder 
nicely when they are up to temperature. Tin plated steel would be ideal and 
I am keeping my eye out for something commonplace that would work well, 
short of finding the real item.

I got my BC-221 a little while ago. What a work of art it is. I have had it

This thing is neat as a pin. No dirt anywhere on the inside. The panel is
not even scratched. The outside box is dusty, but that's all.

I hate to rip it apart for parts. (that's why I bought it)

Someone has even built a little tube power supply down in the battery
compartment. I assume the thing works, though I haven't fired it up. A note
inside said the power cord was replaced in 2001 and it worked fine then.

Not sure what to do next. Can't wind my watch, it is battery powered.

That is the dilemma about acquiring test equipment for parts grazing! When 
you really catch the disease, though, the thing could be a beat up hulk and 
you will STILL want to fix it up and make it do what it was designed to do.

Subject: RE: GB> Q: Recycling Octal Tube Bases

I recently homebrewed some nice coil forms for five-pin sockets using brass
tubing for the pins. I threaded the tubing on the outside with 4-40 threads.
The tubing isn't quite as big as a normal 4-40 screw, but the threads are
deep enough for a steel nut to hang on if one doesn't put a bit wrench on
them. The nuts secure the "pins" in holes drilled in the proper pattern in a
plastic form. 

Brass rod works FB too, but then there is the problem of how to secure wires
to the rod! Especially when the ends are way down inside the coil form. So
tubing was by far the best approach for me.

Subject: GB> BC-221






I got my BC-221 a little while ago. What a work of art it is. I have had it
apart and back together and it is simple and elegant in its construction.
This thing is neat as a pin. No dirt anywhere on the inside. The panel is
not even scratched. The outside box is dusty, but that's all.

I hate to rip it apart for parts. (that's why I bought it)

Someone has even built a little tube power supply down in the battery
compartment. I assume the thing works, though I haven't fired it up. A note
inside said the power cord was replaced in 2001 and it worked fine then.

Not sure what to do next. Can't wind my watch, it is battery powered.

Michael:

Keep it and use it. Or pass it on to a collector. I bought two with 
the same idea in mind that you had. Mine weren't in nearly as 
good shape as yours, but, both work perfectly.

So, although I tried...I REALLY tried...I couldn't bring myself 
to tear either up.

I use one for a signal generator when I have to align a receiver 
at both ends of a band. I use the AN/URM-25 for one end and 
the BC-221 for the other end. Sure saves a lot of knob twisting.

Also, I use it for setting the RAL-7 to exact frequency.

I will probably use one for a VFO also.

I don't think I paid more than $10.00 for either one.

I keep hoping to find a really SHOT BC-221, but, so far, have 
not succeeded.

I don't think there is any shortage of the 221
Tear it up, build something, you'll find another.

Or, mount it whole on your chassis and make a cutout in the
front panel.

The TS-175 doesn't seem real common and that's the
one I want to tear apart.

I had one of those and I did tear it apart. I LOVE BC-221's
and LM units, but the 175 was so drifty it was useless.
So I built my regen into it.

Ron,

That must be some thick walled tubing (thicker than what I am used to 
seeing) if you are able to thread it. The "telescoping" stuff that I see, I 
would think would not hold up even to superficial thread cutting.

I have done this sort of thing making plugs from brass tubing but instead of 
using nuts to secure the "pins", I have soldered them in place in small pads 
etched in a disk of epoxy/glass printed circuit board material.

Try plugging a phone plug into the jack on the front. The destructions say
that unplugging the phone jack turns it off, so it will not drain the
batteries if it is closed up and the power switch left in the on position.

Hey! Thanks Michael! It works now! My dad always said "when all else fails,
read the destructions"

It is pretty darned stable so far. I did see that the power switch does not
turn off the homebrew power supply that is inside. I may have to fix that.

Wait... I just suggested fixing it!! Oh my, I might be getting hooked. I
can hear words in the back of m;y head... They are saying" That is the

you will STILL want to fix it up and make it do what it was designed to
do."

Crap! I think I have become infected.

Oh well, back to looking for another one for parts, sigh.

Oh, btw, it has the book and the s/n on the book matches the s/n on the

Maybe i will key the thing and get on 40 meters.....

Or, perhaps, since I am at work, I should fix something here...

You'll probably want to replace the paper bypass caps in the high

All the coils look like they've never been tweaked since new!

The cabinet could use a repaint. The trim is in great shape. The front

The power transformer is fine.

Those funny white screws in the front fit the cabinet threads and have
plastic backing to prevent panel scratches.

It depends on just how accurate you want to be on 1

If you use it with a frequency counter then it does
make a good signal source if you don't have a service
monitor.

Substitute votes for bids and you have the story of politics.

Yes - the description has a LOT to do with it - also pictures.
Probably in your case the category is OK but some of the stuff I have

Depends on how people search for things.

Yup - that's the one. I thought it would be good for 2 meters perhaps
and mayne even 450 MHz. But mine just wouldn't settle down. Maybe there
was a defective component in it - maybe not, but with a couple of fine H-P
generators here, who needs the grief! My Gertsch is a far finer instrument
than the 175 and I haven't found anyone that want that either (and it has
direct dial calibration).

This is true if yours happens to be stable enough/ Mine was not.
I would say the same for anyone acquiring a LM or BC-221. If you have a
counter, don't worry if the unit does not have the calibration book.
I have a computer program that allows you to make your own "chart"
for these freq meters if you desire.

I won several of the ARRL frequency monitoring tests by using a BC-221
and a counter. Simply beat the signal with the 221 and read the frequency
off the counter. (The counter had been referenced to my WWVB standard).

Subject: GB> Dynamotor(?)

OK, you dynamotor freaks ....

I have here a tiny unit that LOOKS like a dynamotor, has four leads coming 
out of it and all BUT, and this is the confusing part (to me, hopefully not 
to you), it has only ONE set of brushes. What gives? Is this some kind of DC 
to AC dynamotor?

The housing is stamped in barely legible orange ink "14 Volts" ... well, to 
be fair, it takes a bit of imagination to work out the "1", so that is a 
guess. The leads are connected in pairs, i.e. one pair has about 3 ohms 
resistance and the other about 6 ohms between them. I attached the red and 
dusty "green"? leads to a 12.6V battery and observed that it wanted to 
whirr. Well, it DID but I didn't leave it do so for long because I want to 
clean and repack the bearing before doing too much harm. I haven't checked 
what comes out the other leads but it can hardly be DC, or anything 
resembling it, if there are but two brushes.

Also, there is only one "bell". The other end (sans brushes) is open frame. 
I'm not missing a bell, either, if that is what you are thinking.

No markings or other identifiers than what is mentioned.

I recently sold a number of identical items - laser printer drums - over
a period of about 6 months and I used the same listing photo and
write-up each and every time.  The winning bid prices varied from $130
to $40.  I think it just depends of who happens to need what at any
particular time.  And, of course, of how many folks happen to want your
item!

Boy Ron your message sure strikes a chord with me! I have such fond memories
of the 80m Novice band in 1971. It always seemed different than 40m and 15m,
had a different "feel" to it. You are correct in that you really felt at
home there, it was OK to call a slow CQ although to some extent that was
what was great about the Novice ticket and Novice bands that has been lost:
A camaraderie that is just lost when you are thrown into the larger ham
population. I would hang out with fellow Novices at a hamfest or club
meeting. All ages, different backgrounds, skin colors, whatever. We had ONE
thing in common, we were the "low man on the totem pole" and anxious to work
our way up.

I also have fond memories of the slow traffic nets on 80m. They were a great
place to learn proper technique and operator skills. One that really sticks
in my mind was Maryland Slow Net (MSN). You would sign up and get a little
packet of materials in the mail. This would be enough to QNI your first
time. When you did, the net control would have one message for you. Each
time you signed-in you got one message which contained text that explained
how to handle traffic! So little by little you became a Brass Pounder.

Lastly I remember turning the radio on after dinner each night and tuning
that sliver of the band. It would be packed from one end to the other with
CW signals. The only time you hear that today is during a contest. 

Those *were* good days.

Ken-

That TS-175 on my shelf keeps saying, "I want to be the first conversion
oscillator in a Wadley Loop receiver!". If it's stable enough, I can make
the step size small, say 50 or 100 kc. Then use the Q-5'er for tuning the
50 or 100kc block. Probably a commutative mixer. I don't recall Chris
saying anything about noise in these but I believe it's much lower than
the 'linear multiplying' mixers that he's so involved with. State of the
art is MOSFET commutative mixers. The switches have a 2Ohm on resistance
so very little contribution to noise.

All RX are tradeoff and the negative of the Wadley is wide bandwidth
through two mixers and a filter. If the mixers and filter have a wide
SFDR(spur free dynamic range) then it could be a nice RX. Never as good as
something with a really tight first IF filter, but close.

"So Lid Copy"?

I recall we used to send "sld cpy" to avoid that, just was we'd send "he 
will" rather than "he'll" (because we didn't know the apostrophe in Morse). 
Problem solved.

80m is a great band, limited only by antenna size. It was the original Novice 
band (40 and 15 came later), and almost any rig could be made to work there.

One very important thing about 80m is that the propogation tends to change 
slowly, so that if your code is only good for 5 wpm you can get past the 
intitial go-round without the other guy fading into the noise.

80m is much less active today than I recall it being in years past. One 
reason is sunspots - newer hams, used to the easy DX of the sunspot peak years, 
didn't develop an interest. Another is the bad rep of 75 and the mostly-darkness 
nature of 80.

> Do today's operators face relentless criticism? 

I have no doubt that some beginners perceive things that way.  I don't
think they get too much of it on the air, but there's a lot floating
around at ham meetings and on the Internet and such.  Remarks about
the grave dangers of letting those too-easily licensed newcomers get
too much access to the airwaves, where they'll ruin things for those
of us who had to get our licenses the old-fashioned way, abound.  I
wish I could say I'd never heard some OT haul off and start waving
that banner in the company of newly licensed hams on the local
repeater, but unfortunately, it happens.  I don't think they usually
mean anything personal by it, but they fail to realize that one or
more of the people who might be listening, or even participating in
some roundtable or net, might take it personally.  And of course,
when posting to the 'net, or holding forth on the superiority of the
"good old days" at a club meeting, informal get-together, or Field Day
or whatnot, plenty of 'em don't hold back a bit.

Now, on the air, in the context of a one-on-one QSO, I hear very little
criticism, with the exception of an occasional piece of helpful advice,
offered in an appropriate, Elmerly spirit.  On CW, a slow, shaky fist
might make your CQ a little harder for some to hear, but there are
plenty of us who'll be glad to slow down a bit and answer.  Most CW
QSO's are downright warm and friendly.

Experienced hams may be tactless in a careless moment, but few are
downright heartless.

Now, as for the tendency to copy "SO LID CPY"... I think the reason
that happens to so many of us (Yep...happened to me, way back when)
is our lack of experience at copying CW.  We haven't learned to let
the word finish before worrying about what word it is, and so we
think "SO" the moment we realize we have enough letters copied to
form a word.  It's a natural mistake for a Morse beginner, one with
unusual implications, but nevertheless quite natural!

I bought 2 75A4's last year. One in excellent cosmetic condition, working but with only one filter and no speaker for $800 (at a hamfest). The other one was in poor cosmetic condition but had all 3 filters and speaker for $800 (from a local non-ham estate buyer). Both had the 4:1 knob. Obviously, I pulled the filters and speaker off of the bad one and sold it on eBay for about $800. 

There was a time when A4's commanded $1450 but I think that was the height of the dotcom boom. Like the stock market, prices have settled down. Even the hoarders have all the A4s that they want. The market is saturated.

I just don't get it.

My SX-122 in nice workign shape sells for under $200.
Others go for $700

My Collins 75A-4 has a high bid of $786.
It's in nice shape, has the holy "howard mills" modifications
original manual, 4:1 reduction tuning, THREE filters.
One without the reduction, one filter, a big muffin fan sized hole hacked
in the back, a rusty chassis, unknown working condition, AS-IS, no manual
and froNt panel beat up sold for $800.

I'm beginning to believe it's all in the description.
If it's a mangy dog and the seller calls it beautiful, it gets
high bids. If it's nice and you point out the flaws it gets low
bids.

Anyway, if anyone here is looking for a nice 75A-4 with a few small
wartz...

Sure, I could wash it, apply a little touch up paint,
rub it with armorall, Craft my photos to hide the wartz,
and get this on ebay. But I won't!

If the $1450 is too high, wait a few days and send me an offer.

Never thought about changing one to SS but might some time if I run across
a "junker". I have always been more than satisfied with the stability of
the 221/LM meters. But in my experience, the TS-175 is a different animal.

I picked up a 175 a couple of years ago at the
club auction, passed it back to the club for
auction last year as I knew I would not get to
do anything with it.  The one freq meter I had
at one time and have no recollection of seeing
in the surplus or for sale listings is the TS323.
This one also covered 20 Mc to either 400 or 1000,
just don't remember.  But it looked like a very
well made unit.  As I recall, it was grey rather than
the traditional black of the 221/175 types.

Bob, my feeling on the TS-175 was that it would make a good basis for a regen 
receiver project or VFO, but with some severe modifications in either case.

I have another LM style mil surplus freq meter here that I may do that with. Yes, it 
has the book (sorry to the purists!)

Well, the guy I got it from was sure cheerful about it, concidering he only
got 5 bucks plus shipping (which he didn't over charge for like the other
guy)

I got it running yesterday and left it sitting there running, listening on
the R-2000. I tuned the R-2000 to get a low frequency tone that would not
drive everyone nuts and listened for an hour. If the tone changed, I could
not perceive it. I was happy about that.

I did note that the dial position listed in the book and reality were 2
different things, and the "corrector" knob does not have the range to bring
it back.

I took it home, so I can't look at it right now. Hopefully there is a
capacitor in there to tweek the oscillator and get it back in agreement
with the dial?? (then hope it still tracks the same way as when the book
was printed)

The tests at various frequencies and the entry of the numbers into those
books must have taken forever to do on each instrument. I assume they all
have their own individual books.

I thought I could try it as a VFO for the little MOPA at home. I am not
sure how much output the thing has yet, but maybe enough to drive the 6AG7.
It is roughly 4 times the size of the MOPA.....

Is there a spot to find the alignment procedures and such on the beast?

I had another idea as I drove home last night. I have been wanting to build
a Field Day tube TX and RX using a vibrator supply off a 12V battery. I
think I could fit the supply, the TX and the RX all into this (or another)
bc-221 box. It would be pretty cool to use and certainly easy to plop it on
the table out in the trees and work qrp battery powered FD with it. (later,
after 3 or 4 more projects get done)

There are trimmers in the unit. Also most (if not all) have a trimmer on
the xtal osc circuit.

See http://yb0ah.tripod.com/schematics/bc221 for drawings & schematic.
There are variations between the different units, however.

Yes - each unit was individually calibrated with its own matching book.

I am considering converting a BC-221 to a direct conversion receiver.  I 
will move the antenna injection point to reduce radiation from the local

calibration crystal from its socket and then inject the antenna signal at 
the crystal socket pin that connects to the 6K8 triode section and mixer grid.

I remember the first time I got on 30 meters. I was scared, thinking that
it being a CW place, it would be populated with the best CW ops. But I dove
in anyway, only to find that my first contact had a rotten fist, HI. Now no
band or band segment scares me. I rarely if ever go to 20 though. Not sure
why. All my radios work there....

some of those fists out there are a bit hard to copy these days solely
because of the physical limitations their advancing age is placing on them.
To those guys, I offer my most high respect for still being there. I hope I
am still there at their age.

Or they just need more practice. I like to work whoever it is, as long as
they make an effort to send copyable code. (i dislike hearing characters
run together out of sheer laziness though)

Clubs? CW? What's that all about? If you are not interested in bike races,
repeaters, state fair, and cloud watching, the club here offers nothing. I
hope one day the entrenched single sighted ruling class changes hands. Just
my view.

 " Those who can, do.  Those who can't,
> blab a lot."

At a flea market in central Nebraska about 3 years ago I met a local ham.
he asked my call, I told him. Then I was treated to a session regarding how
HE was a REAL extra class ham. (based on his code test) It made me wonder
how his licence was any more valid than mine in the eyes of the FCC. I also
got the impression from things he said that he was just an appliance
operator anyway, and doesn't do CW. I held back the thoughts running
through my mind and vowed not to present that sort of attitude to any new
hams that I met. I was new to being a licenced amateur, but most certainly
not new to radio or electronics.

Yes. That's been my experience as well. People that really know something
generally don't feel the need for recognition or status positioning. I
think it has a lot to do with having the intellect to continue to be
creative and inventive now, not just reliving the times past.

Not sure I know what uncluttered is. If you mean physical stuff laying

uncluttered mind, gee, I am a convict right along with you on all counts.

I remember the first time I got on 30 meters. I was scared, thinking that
it being a CW place, it would be populated with the best CW ops. But I dove
in anyway, only to find that my first contact had a rotten fist, HI. Now no
band or band segment scares me. I rarely if ever go to 20 though. Not sure
why. All my radios work there....

some of those fists out there are a bit hard to copy these days solely
because of the physical limitations their advancing age is placing on them.
To those guys, I offer my most high respect for still being there. I hope I
am still there at their age.

Or they just need more practice. I like to work whoever it is, as long as
they make an effort to send copyable code. (i dislike hearing characters
run together out of sheer laziness though)

Clubs? CW? What's that all about? If you are not interested in bike races,
repeaters, state fair, and cloud watching, the club here offers nothing. I
hope one day the entrenched single sighted ruling class changes hands. Just
my view.

 " Those who can, do.  Those who can't,
> blab a lot."

At a flea market in central Nebraska about 3 years ago I met a local ham.
he asked my call, I told him. Then I was treated to a session regarding how
HE was a REAL extra class ham. (based on his code test) It made me wonder
how his licence was any more valid than mine in the eyes of the FCC. I also
got the impression from things he said that he was just an appliance
operator anyway, and doesn't do CW. I held back the thoughts running
through my mind and vowed not to present that sort of attitude to any new
hams that I met. I was new to being a licenced amateur, but most certainly
not new to radio or electronics.

Yes. That's been my experience as well. People that really know something
generally don't feel the need for recognition or status positioning. I
think it has a lot to do with having the intellect to continue to be
creative and inventive now, not just reliving the times past.

Not sure I know what uncluttered is. If you mean physical stuff laying

uncluttered mind, gee, I am a convict right along with you on all counts.

Admiral Daniel V. Gallery, U.S.N., was most famous for capturing the U-505,

(roughly) one great line from "Now Hear This!" that may be applicable to
this "old-timers" subject.

"Fatso concluded the outrageous lie he had been telling, and added, "life in

How about field day portable rig with a Tube MOPA xmtr

You could either use acorn tubes, nuvistors or those 
tiny pencil tubes so as not to strain the batteries too much.

Does anyone have a source for 45 V batteries these days?
Heck you could use four or five of those small 12v gell cell

If I were to convert a freq meter to SS I would opt to do it to an LM
rather than a BC221 because it is a smaller, more portable unit (although
I think harder to work on).

Subject: GB> The Old School ( or: R U a Lid

Hi, gang:

Hee,  i love it when my grizzled vet brethern break out
that banner and wave it.  Hey, i respect the hurdles
they had to jump to get their licenses the "old way".

I had to do that too, so i guess i am one amongst those
"old schoolers" living just under the Conditional Class
distance limit required an early 5 am rise in pilgrimage to
the FCC office on Lois St. in Tampa, take the code and
written after 2 years of novicing and reading and trying
to make sense out of theory by the only way i knew 
how to: homebrewing and becoming One with "Understanding
Amateur Radio" 1971 ed.   

Ever become "one" with a book?   Interesting, to say the least . . . .

Alas, i am a mere "old school" General, who never saw the
need for those extra 25kc or so of cw space.  Andt since i am
but a General, i cannot stand in the shoes of a genuine, ribbon
bedecked 1x2 Extree Class (sigh) hero.  

But, i have to ask my hero here, Heinrich Hertz Johnson,
w4xy, self proclaimed "Old School" Extra:          just which
"old school" do you hail  from?  Oh, there are several, and each
claims some sort of Regis Signat over the other.  Each had
their own "massada" to climb, higher and more vigorous than 
the fella after him, climbing another "massada".

You can see a lot revealed in the "correspondence from members"
section of QST from any era.  These are must-read columns, you
can learn more from those than many of the tech articles, y'know.

There were the guys that were around before regulations as we
know it.  These were the guys that were coralled to take the Navy
test when it became beneficiary of the Ether in the US.  Then
there happened the DOC: licensing requirements and testing changed.
Now the old school was the Navy tested "pre ban" 1914 ham
vs the Post armistice new regulatory ham.  Then came FDR and
the FCC.  Now there were the "Pre Cairo" old school and the newly 
licensed FCC licensees.  Read the pointed invective-laced
letters from the disgruntled "King Spark" era guys. They were
the new BMOC. These new guys buy receivers!  Lord, Lord. . . 
These new guys never knew spark.  These new guys don't know
what ozone smells like.  Never rocked a rocker.  Only knew
house wiring.  Don't know the value of things ( never mind the
country was steeped in a world wide depression, and only
a few could afford to purchase a receiver, and those that made
them often out-performed the best of those '20s microphonic battery
0-v-1 gennies. )

The "pre-cairo" bunch became so vocal over the 'gagging' restrictions
placed upon them by new regulations  that The Old Man  had to put 
an editorial in the August 1929 QST to address it.  It's a good 
read, called "Bucking". ( Hiram understood the difference between
"freedom of speech" and working withing a regulatory environment
which had international consequences and exerted influence on public
health and safety. Something many hams to this day seem to miss.)

By the time armistice and Cairo were becoming a faded memory
another Ban happened in Dec. 1941.  At the end of 5 years
there was yet another catagory of "Old School" that could have
something to lord over the aspiring newbees, and you could catch
snippets of this in some of the letters to the editors.  Really
kinda fun to read. "Having been licensed since 1927, and a
League member since 1929, **I** feel . . . . "  Seems to be
a sort of regular preamble. Or mantra.  There was something 
about being licensed "Before the War".  Looking over the 1940
and 1946 handbooks, i have yet to see just what that was . . . 

Oh, yeah, incentive licensing.  Bane of all banes.  If you got
your license under this license structure,  you were just sorta . . .  
handed your license. Never really had to know anything.  
Or so one would gather from the vociferations of the grizzled
"Old School" vets.  Some pretty sharp barbs in the 1950s 
mags over this one.  This was my first experience with any
sort of "banner", the pre-incentive-license holder banner.  Long
may she wave . . .   Another drum to beat.

In all fairness, it was during many of these changes, bands and 
sub-bands allocation changes that some Classes of licenses 
( What?  Class?  why, we never NEEDED classes in 'ott-nine! ) 
--had to bite the bullet in deference to allowing newbees or lower
classmen  on once primordal holy hunting turf. This, of course, 
only served to galvanised those predisposed to banner waving.
The ill-advised snipping off of 11 metres for CB didn't help things,
either, and providing a new moniker for the 'Old School' to use.

Then morphed the Novice class.  Old Schoolers balked, but
oddly enough, you don't find quite as much press fuss made.  
Maybe it's because these were identified newbees, and it got 
some 'o da tuff guys right here < thumps pericardial chambre>, 
a spot only occupied by baby brother and mom.  :>)  Ahh, but 
there were some dissenting old schoolers just the same.

Does anyone recall "Pre-WARC" hams doing recitations of
"what they had "?  "You guys don't know what it means
to have . . . .  ( insert noun here.) That has always mystified me.
It seemed that there was some virture of being a ham before
the WARC, and some dubious attache applied afterward.  Never
could figure that one out, we were ALL dodging the Russian 
Woodpecker!  Pre-WARC six-band hams turned out to be hams most
of which were 'handed their licenses', according to the pre-incentive-
licensed hams, who in turn really didn't know what REAL testing
WAS according to the pre war hams who in turn really didn't know
hamming because they purchased their receivers at a store according
to the Hoover DOC pre FCC hams, who's judgment might be impared
if they were licensed AFTER the cairo convention, but according
to the pre Ban hams, this bunch really have no leg to stand on because
they didn't do things the Navy way, who in turn were probably part
of the disorganised rabble that caused the Navy to step in and 
regulate Amateur Wireless to begin with! ( take a deep breath.)

Today's Old School:

Now comes the latest go-rounds.  CW requirements slipping
away like mercury on a shag carpet,  the elimination of certain
license classes,  and certainly some folks are thinking some of
the gold in their skills repository are turning to brass, the things
they did, the achievements they accomplished losing some polish,
a diminuation of what was once their highest order of achievement
perhaps.  This has happened --as i more or less accurately described--
many, many times.  But the bottom-line always remains the same:

It's what you put into this Endeavour that determines your standing in
the eyes of others.  And no amount of banner waving will change that.
It seems the humblest ham often turns out to be the highest of the
achievers, and eventually . . . that gets out.  Sometimes he/ she's a
cut from the old fabric.  Sometimes not.

A very great man once said " When you come as a guest to the
table, seek the lowest seat, and let your host invite you to a place
of higher honour.  Never assume the highest seat lest the host
ask you to step down to a place of lesser import, to make room
for a still more noble guest.  Great will be your shame."

Moral 1: always be a novice at heart.  

Moral 2: respect yer elders, young squirts.  One day
YOU'LL be the "Old School" grizzled vet.
Moral 3:  Even a fool who remains silent is considered to be wise.

Great points Gary!

What I notice that tells the that it's going to be a great QSO is when we
move off of the "formula". Sometimes I'll do something very simple at the
opening round to help that happen like:

"RIG HR K2 AT 100 WATTS INTO AN INVERTED L ANT..." 

Notice I didn't say "ANT IS INVERTED L", like most do in formula QSO's. 

When the other guy comes back with something like "FB UR INVERTED V ANT..."
I suspect he's just trying to copy key words and not getting it right.

But, when the other guy says "FB ON INV L I HAVNT RUN INTO ONE OF THOSE IN
WHILE...." I sit back and smile and get ready for a great Rag Chew.

In any case, for the first guy, I'll come back with "ANT HR IS NOT INVERTED
V, ANT IS AN INVERTED L - INVERTED L - STRAIGHT UP 30 FEET AND HORIZONTAL 30
FEET AND FED AT END." 

The guys copying key words won't get better without practice. So I'll append
a question about his rig/ant, etc. and see if he can answer it. 

Either he says "FB OM TNX ES 73..." or he comes back with an answer and
perhaps a question of his own and we're "on" for another round. 

Ya can't learn a language by using it only for asking directions to the

Excellent analysis, but you left out my favorite one.  Remember
back when Novices were required to use crystal control and
limited to 75 Watts and CW only?  Then, they dropped the
crystal control requirement, upped the power limit, and even
gave them voice privileges on some of the bands.  Why, back
in my day, they had to use crystal contro....err, never mind.  :*)

Hi, gang:

Hee,  i love it when my grizzled vet brethern break out
that banner and wave it.  Hey, i respect the hurdles
they had to jump to get their licenses the "old way".

I had to do that too, so i guess i am one amongst those
"old schoolers" living just under the Conditional Class
distance limit required an early 5 am rise in pilgrimage to
the FCC office on Lois St. in Tampa, take the code and
written after 2 years of novicing and reading and trying
to make sense out of theory by the only way i knew 
how to: homebrewing and becoming One with "Understanding
Amateur Radio" 1971 ed.   

Ever become "one" with a book?   Interesting, to say the least . . . .

Alas, i am a mere "old school" General, who never saw the
need for those extra 25kc or so of cw space.  Andt since i am
but a General, i cannot stand in the shoes of a genuine, ribbon
bedecked 1x2 Extree Class (sigh) hero.  

But, i have to ask my hero here, Heinrich Hertz Johnson,
w4xy, self proclaimed "Old School" Extra:          just which
"old school" do you hail  from?  Oh, there are several, and each
claims some sort of Regis Signat over the other.  Each had
their own "massada" to climb, higher and more vigorous than 
the fella after him, climbing another "massada".

You can see a lot revealed in the "correspondence from members"
section of QST from any era.  These are must-read columns, you
can learn more from those than many of the tech articles, y'know.

There were the guys that were around before regulations as we
know it.  These were the guys that were coralled to take the Navy
test when it became beneficiary of the Ether in the US.  Then
there happened the DOC: licensing requirements and testing changed.
Now the old school was the Navy tested "pre ban" 1914 ham
vs the Post armistice new regulatory ham.  Then came FDR and
the FCC.  Now there were the "Pre Cairo" old school and the newly 
licensed FCC licensees.  Read the pointed invective-laced
letters from the disgruntled "King Spark" era guys. They were
the new BMOC. These new guys buy receivers!  Lord, Lord. . . 
These new guys never knew spark.  These new guys don't know
what ozone smells like.  Never rocked a rocker.  Only knew
house wiring.  Don't know the value of things ( never mind the
country was steeped in a world wide depression, and only
a few could afford to purchase a receiver, and those that made
them often out-performed the best of those '20s microphonic battery
0-v-1 gennies. )

The "pre-cairo" bunch became so vocal over the 'gagging' restrictions
placed upon them by new regulations  that The Old Man  had to put 
an editorial in the August 1929 QST to address it.  It's a good 
read, called "Bucking". ( Hiram understood the difference between
"freedom of speech" and working withing a regulatory environment
which had international consequences and exerted influence on public
health and safety. Something many hams to this day seem to miss.)

By the time armistice and Cairo were becoming a faded memory
another Ban happened in Dec. 1941.  At the end of 5 years
there was yet another catagory of "Old School" that could have
something to lord over the aspiring newbees, and you could catch
snippets of this in some of the letters to the editors.  Really
kinda fun to read. "Having been licensed since 1927, and a
League member since 1929, **I** feel . . . . "  Seems to be
a sort of regular preamble. Or mantra.  There was something 
about being licensed "Before the War".  Looking over the 1940
and 1946 handbooks, i have yet to see just what that was . . . 

Oh, yeah, incentive licensing.  Bane of all banes.  If you got
your license under this license structure,  you were just sorta . . .  
handed your license. Never really had to know anything.  
Or so one would gather from the vociferations of the grizzled
"Old School" vets.  Some pretty sharp barbs in the 1950s 
mags over this one.  This was my first experience with any
sort of "banner", the pre-incentive-license holder banner.  Long
may she wave . . .   Another drum to beat.

In all fairness, it was during many of these changes, bands and 
sub-bands allocation changes that some Classes of licenses 
( What?  Class?  why, we never NEEDED classes in 'ott-nine! ) 
--had to bite the bullet in deference to allowing newbees or lower
classmen  on once primordal holy hunting turf. This, of course, 
only served to galvanised those predisposed to banner waving.
The ill-advised snipping off of 11 metres for CB didn't help things,
either, and providing a new moniker for the 'Old School' to use.

Then morphed the Novice class.  Old Schoolers balked, but
oddly enough, you don't find quite as much press fuss made.  
Maybe it's because these were identified newbees, and it got 
some 'o da tuff guys right here < thumps pericardial chambre>, 
a spot only occupied by baby brother and mom.  :>)  Ahh, but 
there were some dissenting old schoolers just the same.

Does anyone recall "Pre-WARC" hams doing recitations of
"what they had "?  "You guys don't know what it means
to have . . . .  ( insert noun here.) That has always mystified me.
It seemed that there was some virture of being a ham before
the WARC, and some dubious attache applied afterward.  Never
could figure that one out, we were ALL dodging the Russian 
Woodpecker!  Pre-WARC six-band hams turned out to be hams most
of which were 'handed their licenses', according to the pre-incentive-
licensed hams, who in turn really didn't know what REAL testing
WAS according to the pre war hams who in turn really didn't know
hamming because they purchased their receivers at a store according
to the Hoover DOC pre FCC hams, who's judgment might be impared
if they were licensed AFTER the cairo convention, but according
to the pre Ban hams, this bunch really have no leg to stand on because
they didn't do things the Navy way, who in turn were probably part
of the disorganised rabble that caused the Navy to step in and 
regulate Amateur Wireless to begin with! ( take a deep breath.)

Today's Old School:

Now comes the latest go-rounds.  CW requirements slipping
away like mercury on a shag carpet,  the elimination of certain
license classes,  and certainly some folks are thinking some of
the gold in their skills repository are turning to brass, the things
they did, the achievements they accomplished losing some polish,
a diminuation of what was once their highest order of achievement
perhaps.  This has happened --as i more or less accurately described--
many, many times.  But the bottom-line always remains the same:

It's what you put into this Endeavour that determines your standing in
the eyes of others.  And no amount of banner waving will change that.
It seems the humblest ham often turns out to be the highest of the
achievers, and eventually . . . that gets out.  Sometimes he/ she's a
cut from the old fabric.  Sometimes not.

A very great man once said " When you come as a guest to the
table, seek the lowest seat, and let your host invite you to a place
of higher honour.  Never assume the highest seat lest the host
ask you to step down to a place of lesser import, to make room
for a still more noble guest.  Great will be your shame."

Moral 1: always be a novice at heart.  

Moral 2: respect yer elders, young squirts.  One day
YOU'LL be the "Old School" grizzled vet.
Moral 3:  Even a fool who remains silent is considered to be wise.

The only slightly disparaging remark I've heard in a QSO from an OT was one
recently who poo-poo'ed me for having gotten a Novice ticket instead of
passing the 13 wpm test directly like he did after a few days of practice. 

I replied that, considering how much effort I put into learning the code, he
- like all the ops who say they picked it up after a short period of casual
study - could never understand the depth of pleasure we got from using it
after months or years of diligent effort to master it. 

I've often said, and it's partially true, that I think CW has remained my
dominant (>99%) mode over all these years because I wanted to get my
"money's worth" for all the effort I put into learning it!

There is, but don't go there yet.

The first order of business is to get the xtal oscillator dead-on 1000 kc. 
Its trimmer is usually located behind the name plate (that's why the namplate is 
held on with teeny screws).

Warm everything up and tune in WWV on a *AM* receiver, the higher the better. 
Turn the xtal osc on (only) and listen for its harmonic beating against WWV's 
carrier when there is no modulation on WWV. The little trimmer under the 
nameplate should get the xtal dead-on zero beat. If not, the *xtal* may have aged 
out of cal.

Once that's done, you can check the variable osc against the xtal by plugging 
in a pair of 'phones and tuning in the calibration check points printed in 
the book. See how far off they really are.

They do, but their calibration was almost automatic. It was *not* done by 
laboriously measuring each point!

As I understand it, the units were calibrated by first setting the xtal osc 
dead-on, then tuning in each of the calibration points. The exact dial readings 
were then fed into a specialized calculator (136 tubes, I think) which 
automatically interpolated/calculated all the actual dial points and typed out the 
cal book. Incredible for its time. There are emulators available on the web to 
do the same thing now.

That's one way, but it's a lot of work! Consider trying this:

BC-453 Command set rx with xtal controlled converter in front for 80 and 40 
meters.  Rx needs 220-240 volts dc at about 40-50 mA, 12 volts at 0.9 A for the 
heaters. If you use a simple 1 tube converter (say a self-excited 12SA7 or 
better yet a 12BA7)), the heater load is just  .15 A more and the plate a few 
mills. (I've done this and it works great. No, the  pentagrid is not the best 
front end in the world but in all the places I've tried it the antenna noise 
overrode the front end noise by many dB).

For tx, use the BC-221 as a VFO (take out the unneeded tubes) driving a 12A6 
or similar final. Same vibrapack or dynamotor drives both rx and tx. Mayve 
0.45 A heater current....(I haven't done that - yet

I don't know how it is elsewhere, but the 9v battery powered smoke detectors
I use here sound their low battery squeaks when the batteries read close to
9v on a multimeter.
Maybe the smoke alarm people are in league with the battery manufacturers.
The good news is if you know someone with a lot of smoke detectors you will
have a source of very usable radio B batteries.

Yes, and they will not last nearly as long.

The last time I needed 45vdc, I bought four rechargable lead acid batteries at
$5 each.  Series connected they deliver 48 volts and they can be recharged.
However, they might not fit into the shell of your Dick Tracy wrist radio.

That's been my experience exactly. 

When the other guy hears:

"RIG HR HOMEBREW HOLLOWSTATE XCVR 100 WATTS TO INV VEE"

it's often a good long ragchew explaining the rig. Once in a while, the other guy is also running homebrew, in which case it's *really* interesting. 

In one recent QSO I was running the 100 W hollowstate xcvr and the other guy was running a 3 watt SS homebrew setup with separate rx and tx. 

btw, way back in "Novice Accent" (remember that article?) times I read that if you sent "R" it meant "solid copy, OK on everything" and so there was no need to rehash what the other guy sent unless it was to add a comment. 

We need to bring back articles like that..

Demand rises and falls. Photos and descriptions also make a difference. I
got a telegraph key as a part of an old homebrew code practice oscillator
for a very small price. Another sold for over $2,000 when properly
identified. Of course, I had taken a chance based on a guess about what was

I just bought a PRC-47 with the complete Zero shipping case set, antennas
(whip, longwire and NVIS crossed dipole with base), straps, backpacks, and
all of the accessories that come with it including the handset, speaker and
knee telegraph key, remote control hardware and so on in the sealed plastic
bags. I was the only bidder. Got it for rock bottom minimum of the PRC-47
alone. Did not even think that would happen.

The photos just did not show all of the options nor list them. I took a bit
of a chance and was very pleasantly surprised.

In short, it is a free market and follows it's own rules of the day and

Several years ago I acquired an RCA Radiola AR-812
which is the "Super 8" portable radio superheterodyne
that was made in 1924.  It is completely
self-contained (weighs about 40 pounds with the
batteries!) with antenna, batteries, tubes, everything
except the speaker or headphones are contained within
the case.

In it I discovered a "C" battery (4.5 volt) that had a
code date of 1927.  A friend of mine saw the battery
and wondered if it was putting out anything.  I got
out my VOM and, sure enough, the 1927 battery was
still putting out almost 4 volts 60 years later!

Sorry guys - What I meant to say for a source was NOT old stock "B" Batteries.
I remember when there were plenty old ones still around to buy.
Fair had a few back in the 80s and maybe even the 90s,
but I think they are all gone.

What I actually had in mind was other alternatives... but something beefier than a 
string of little 9V dry cell "piles" (batteries.)

I would want to use something beefy and rechargeable!

Subject: Re: GB> RE: Your Novice Accent

Interesting memory sparked there.

When I was a kid, W6DTY lived one street over and about a block from my
home (He lived on Laurel, I on Maple).  He was to teach my buddy, Hurlon
Luck, and I the code in preparation for taking the Novice test.  I think
we were 11 or 12 years old at the time.  I only recall meeting at his
place one time.  It was dimly lit inside and as I recall, Keith smoked. 
I vaguely remember being shown his shack.  Big rack mounted stuff with
lots of meters and dials.  For whatever reason, the lessons never
materialized.  I don't know why, maybe he thought we were too immature or
something.  The memory is just too hazy.  I think that same house is now
occupied by another Ham, but it may be one or two houses either side of
Keith's old place.

Anyway, about 4 or 5 years later and thanks to the Santa Clara High
School Amateur Radio Club, Ed Sanders WA6VJP (my Elmer) and a bunch of
other Hams who contributed to the club, I made it.  And the rest, as they
say, is history :-).

On the subject, I always just send 'R' and 'FB' after the exchange if it
was solid copy.  And I also find that asking a question of the other op.
will either result in a quick "gotta go" or break the "formula" and begin
a nice rag chew!

OK...
I have noticed this, too.
BUT...
how do they test under load?
Draw about 25 mA from one and then check the voltage while doing this.
It's suggested to change the smoke detector battery every 6 mths. or so
regardless.
At a buck or so per battery, it's cheap protection.
I usually put them in the remotes for the tv's, etc.
The low battery indicator on smoke detectors activates depending upon
where on the discharge curve the voltage is. That's why some detectors
specify ONLY zinc carbon or ONLY alkaline, etc.

I hate them, too.
Best approach probably to load all the smoke alarms in one's establishment
with new batteries on the same day and change the lot when one first hears a
beep.
But frugal Scots and old time Kiwi "wars and depressions" attitudes hard to
extinguish in small matters if not in large.
So I have ended out at times carrying smoke alarms one at a time in my
pocket trying to identify the one that is beeping.
Do not show this message to your Significant Other, it will be rightly taken

Here are some more ideas:

- Some types of Polaroid film packs have an internal flat battery rated at 6 
volts. I have tested these batteries after they had been in storage for well 
over a decade and found them to be in good condition. Long after the film is 
used or has expired, the batteries are still good, and with seven of them you 
get ~42 volts. Of course you have to dream up some sort of holder, but they do 
the job. Never saw one leak, either.

- There's a variety of small "lithium" cells used in 35mm autofocus cameras 
that are discarded when they no longer have the capacity to operate the camera 
motors. These batteries often have plenty of capacity left for use as B 
batteries.

I'll bet that five 9 volt batteries cost a heck of a lot less than any 45V

Here are some more ideas:

they do the job. Never saw one leak, either.

that are discarded when they no longer have the capacity to operate the came=

Good idea if you know someone that uses Polaroids. I don't think they're
that common any more.

Might wanna talk to someone at your local camera shop and have them save
the discards for you.

New 6 or 12V gelcell batteries are not that expensive (the 4AH variety).
One could build a small DC-DC converter to get B+ off a common battery.

Regeneration is certainly an option but I prefer to use a double-tuned input 
circuit. Maximum simplicity and low drain are important requirements for the 
FD application, and every additional tube is more AH out of the battery. The 
'453 has plenty of gain so the front end doesn't need too much. 

A worthwhile improvement in Command set rx performance can be had by using a 
12SG7 in the RF amp. Also, be sure that your 'phones match the output 
transformer impedance.

Another approach is to build a band-imaging 80/40 rx from scratch. If you can 
get the xtals, a sharp IF at about 1700 kc. will do the job. But that's a lot 
more work, and band-imaging rx's can fool you in a contest.

Just think - you could make it into a transceiver too, by just increasing that 
"regeneration" to the point that she oscillates.

Subject: GB> Rotary Inverter

OK, I got the rotary inverter 
(http://www.geocities.com/alibhernlem/Radio/Invert.html) ... I believe that 
is the correct term ... cleaned up and relubed and ran it up at 14VDC.

The output is indeed 28VAC as one list member suggested. With no load, the 
output frequency is about 360 cps or so and the unit draws about 1.33A in. I 
applied a 25 ohm load to the secondary to see how much this would affect the 
operation. The unit bogged and the speed fell. Current in went over 3 amps. 
The output voltage waveform changed to a triangular shape and dropped 
significantly. The output frequency fell to about 250 cps.

So I think that it is fair to say that this unit is not meant to provide 
even 1A output.

Anyone recognize this specific unit or can tell me what rating a similarly 
sized unit is expected to produce?

Thanks.

Hey Mark,

Wow. Well, the way it went for me was he called CQ with the KL7 call sign
and I answered. Then we said some standard QSO stuff back and forth, and
when he described his rig, that is when he did the fast thing to me. I wish
I had a recorder so I could slow it down and see what he said.

This has been  a couple years ago I think. I may be able to find it in one
of my spiral note pads. I used to write down everything in there, then
transfer the log data to the log book. These days I only write the log
stuff, and other interesting pieces and copy in my head the rest. Some guys
I do write it all if they are not sending well. I find that it helps me
stay on track.

I bet it's the same guy. I can't imagine there are very many CW OPs that do
that. I don't even try to speculate on why someone would do that, too many
possibilities. for all I know he could have been calling himself an a-hole,
which would be pretty accurate.

I told a couple people about it here locally on 2 meter simplex, but have
not mentioned it on the internet before yesterday. It floors me to hear
that someone else was struck by him as well.   :-)

Subject: Re: GB> B+ Batteries

I remember tearing appart a dead B battery once, and it was
composed of an array of five by six dry cells soldered/welded? 
together in a cardboard carton and potted in tar.  The 
batteries had separators formed by an array of cardboard 
sheets with slots cut so that they interlocked together to 
form the array.  Given the talents in this group, it should be 
possible to make a cardboard carton, complete with the 
array made from the cardboard sheets with interlocking 
fingers, and then insert and solder [1] together the 30 dry cells 
required.  Optionally, it could even be potted in tar if someone 
desires.  Plus, somewhere I've seen an image that can be 
printed out and glued on the case to make the battery look 
exactly like one of the old B batteries (Although I'm not sure 
about copyright issues associated with the image.  However, 
you could always design your own.).

[1] Add the appropriate safety warnings about soldering 
batteries, flamability, explosiveness, etc.

The only thing I don't recall exactly is what size the dry cells
were in the B battery I disassembled.  I'm thinking that they
were roughly the size of an AA cell, but it's been a LONG time
ago.  I do remember that the zinc case was exposed on each
cell, since there was no reason to slap a label on it, because
the cells were potted in tar in the assembled battery.  Now, 
how much would 30 AA batteries cost?

Of course, that's only if you really wanted to be original.  I'm
leaning toward using a 12 volt gell-cell with a solid state
(Whoops, sorry guys/gals.) inverter driving a capacitive voltage
multiplier ladder [2].  Or, the other approach would be a solid state
inverter driving a stepup transformer.  With either arrangement,
you could always use a voltage regulator tube to regulate the
output, just to make it somehow related to tubes.  :-)  If you 
designed the capacitive voltage multiplier ladder correctly, you
could even pull taps off for different voltages (22.5, 45, 67.5, 90,
etc.).

[2] I'm toying with a 555 timer chip driving an H bridge configuration
of switching transistors which drives a ladder of capacitive voltage
multipliers.  The good news is that you can run this circuit as fast
as you want, which minimizes the size of the capacitors needed.  
The bad news is that 1N4007 [3] diodes don't like to be run real fast.

[3] Why am I using 1N4007, instead of lower voltage diodes?  
Because they're there.  I have a good stock of them, but my stock
of lower voltage diodes is somewhat limited.

I spoke at the local phone guy for MCI up here in
Silver Springs where i work.  He has been funneling
spin-off phone equipment to me now for about a year,
giving me first up on stuff that's about to go into the
compactor. 

Among these were 45v batteries.  Seems the phone
company also found the regular 45v batteries just a
tad to costy, so they just hollowed out a few boxes
and stuffed them with penlites from Family Dollar.
(They needed higher current than 9v batteries could
handle.)  But . . . these batteries were dead.  So i figured
i'd just bite the bullet and make my own, too.  I have
a large Burgess add that featured a life sized B battery
wrap-around lable on the back of one of my old QSTs.
Maybe i can scan it and produce a replica B battery.

The topic of old batteries and making reproductions of the same comes
up fairly often in the usenet group rec.antiques.radio+phono. The
folks in that group will likely post some images to

Take a look at:

http://www.roberts-radios.co.uk/batteries/batteriesframe.htm

This guy has most common domestic and foreign batteries scanned in high 
resolution.  Most give all sizing details as well, so it's easy to print 
and create an actual reproduction.

I've used this source may times to create replica batteries for old tube 
portable radios.

From: "Davies, Doug A FOR:EX" 

Subject: GB> Tube Problem

A couple of weeks ago, I was asking if anyone had any spare 6F7M tubes for
an old Canadian broadcast set I'm fixing up.  No one came through with any
of those but it was suggested I use 6F7S's in place of the "M"s.   I managed
to find a couple of the "S"s and here is where the problems start.  

First, the base pinouts of these two tubes are very different.  The "M" is
an octal and the "S" has seven very large pins and no center guide.  So, a
direct substitute is not possible.

Second, I am unable to locate a base diagram for the 6F7M.  The "S" and the
regular 6F7 appear to be similar.  Unless I can find a base diagram for the
"M", I won't be able to figure out how to wire in the "S" in its place.
And, I would rather not butcher this old radio to change tube types.

I guess I have two choices....keep trying to locate a couple of "M"s or just
put the radio back together and use it as a display model (yuk).

So, I'm appealing once again to anyone who may have at least two 6F7M tubes.
I need to find these or the project is over.  And, before I get the typical
"check the internet" response, I have done this and there are indeed two
sites that list the 6F7M.  Neither have replied to my requests.  One is the
VE2TUB site in Quebec and the other I can't remember the name of at the
moment.  And, if anyone has any other suggestions as to how I may solve this
dilemma, I'm all ears.

He used the 9 volt (10 pack) packaging to hold his high voltage battery

 Itokawa will gradually close to earth and, on June 26, 2004, it will be
closest to earth with distance of 0.013AU (about 1.95 million km). But,
unfortunately, it will be then located at the south hemisphere. It is
estimated that the asteroid will become about twelfth magnitude (about
1,500 times brighter compared to the present).

OK, so we have June 26...

26 Jan to 26 June is 152 days, not 146. This is the kind of error a high

This is "Itokawa" and it's a southern(hemisphere) sky event. Maybe a trip
to Fiji for a look. Need a guide? I know my way around.

There are plenny of astronomers who don't work for 'da gummint' not to
mention all the amateur astronomers who have decent scopes.

Perhaps they are talking about fathers day which was 146 days out from the
time of the transmission? Maybe they are at a remote post and expecting
a fathers day care passage from home. The dots connect better than those

Subject: GB> Rechargeable  B+ Batteries

There are several sites on the web for companies that will build you a NiCd
or Nimh rechargeable battery in just about any configuration. If you did it
with common A or Sub-C cells it would take 30 of them. They may have access
to 9v rechargeable or cells with some other voltage. They will weld the tabs
and wrap the whole mess in heat shrink at pretty much no cost vs. the cost
of the raw cells themselves. As a reference, AA NiCd cells are $1.10 each
and Nimh cells are about $2.00 each.

I know this is much more expensive than a few 9v batteries, but it would run
a radio a LONG time and providing you recharged it periodically would last
you years. My experience is that the additional cost of Nimh is well worth
it.

I've been in contact with them recently for a different product, but I'll
look into what it would take to have them build a 45v version. They seem
VERY willing to work with customers.

Odd coincidence...
got a (spam) note from an astrologer this morning talking about a "Venus
transit" and some sort of eclipse involving the Sun, Venus and the Earth on
June 8th of this year.
Supposed to be a good thing, as such hasn't happened since 1882.
Seeing that it's over a hundred and twenty years later (than 1882), i don't

Whatever anyone else offers for all of the unloaded gear in anticipation of
the end of the world, I can go lower. After all, if you are going to make
that big parachute jump into the unknown you want to jump clean and it would
not look good if you seemed to have profited from the sale of your
equipment.

Me? Well, I know where I am going anyway so I will just have to take my
chances.

I think that might be a good idea.  Send me a list of what you have, and be

If you truly want 45 volts, it will take a few more of those cells than 30 
(1.2V per cell).

A few months ago I picked up some NiMH AAs for $0.25 each at the flea 
market. They were in unopened packs of 4 and I only bought a few packs 
because I wasn't sure whether they were yet any good. So far they seem to be 
going strong and I am kicking myself for not purchasing the whole lot.

So anyway, the point is that you should keep your eyes open to such 
opportunities. They ARE hitting the surplus markets.

You can find 9 vdc NiMh batteries if you look around a bit.
I got D cells for my DX440 from Global Electronics in Mississauga a few
years back.
Checkout:
www.globalsemi.com
look for item NIMI-9V
150mAH
replaces GP15F7H
Catalog list is $8.90 each Cdn
Check updated pricing on the website.

There's a guy in B.C. (Canada) selling NiMh batteries and chargers on that
auction place.
Several brands and sizes.
I bought about 4 dozen AA's and a fast charger with the car kit from him
last year.
He probably has 9v ones also.

When I was a lad, about 60 years ago, we lived on a farm without electricity. 
We had battery operated radios that typically used  90 volts for B+ and 1.4 
volts for the A filament battery.The A and B batteries were in one pack about 
4" wide by about 6" high by about 14" long.  I am guessing from memory, since 
that was a long time ago. The cells were all standard D size. The B+, of 
course, consisted of  60 cells in series and the A battery consisted of, I would 
guess, about 20 cells in parallel. These battery packs cost about 5$, if I 
remember correctly, which was pretty expensive for the time, but they lasted about a 
year. We listened to the radio about 3 or 4 hours every night.

Thank you! 

Interesting story -- without the asteroid fantasy. 

The most likely explanation was offered by a Briton via e-mail:

"I think some of the people making comments on here do not understand some
of the background facts. British Military often arrange "holiday's" for its
staff, in the same way that my employer (not military) has a ski club, rugby
club and lots of other societies that arrange trips abroad. The majority of
the people on this trip are military personnel but at least one is a
civilian and they are all on leave. Also they where aware that the cave
could flood and they have food, water and communications already set-up in
case a flood occurred and are apparently in no real danger. .."

When we get "whacked" by a big 'un, it would be good to be a few hundred
miles from the impact point, but beyond that being underground is the least
desirable place to be. After all, there will be seismic reverberations all
around the globe. Who wants to be in a cave then? What cave is going to
stand up to a direct hit? 

Our big issue, as a species, will be to eat. We'll have a "nuclear winter"
long enough for virtually everything we depend upon to eat dying.

Subject: GB> Heathkit HO-10 scope problem

Maybe someone out there can give me some advice on this.

I have an old Heathkit HO-10 scope that looks like it was built yesterday. 
It has one problem. Intermittently, I get nothing on the scope when I turn 
it on. Most of the time it works perfectly. But every once in a while when 
I turn it on (1 out of 5 times maybe?), the tubes light, the pilot lamp 
lights and everything looks like its working, but no scope output. I can't 
see the scope tube well, but it doesn't look like its lighting inside 
either (maybe its not supposed to).

All the large voltage capacitors seem to check out, all the tubes check out 
perfectly and no broken solders or leads that I can see. The testing 
procedure in the scope's manuals checks out perfectly every time. Any ideas 
on what the problem might be or where to start looking? Is the scope tube 
itself likely to go bad like this?

Thanks.

Not an ancient, but getting there 

gg:
hmmmmm. Haven't seen it done, but why not?  Looking at the plate curves and
interpolating/guessing (curves are for +300v screen, +40v suppressor), it
would require little negative bias voltage for deep cutoff if the screen and
suppressor were directly grounded.    Would probably run ok for class B at
zero bias.  Triode operation requires much more drive of course.

50/70 ohm passive resistor / swamped input w/ no LC:
Nope -- would require over 50 watts drive to produce the needed grid
voltage.

500 to 2000 ohm grid swamping resistor:
This is doable.  Since it is single band, you could use a simple low-Q
(relatively wide-band) L-net to get from a 50 ohm input terminal to the
impedance of the grid resistor and grid.  Would still require 5 or 15 watts
drive -- but make it very stable.  I built an 813 AB2 amp like this that
worked well.

BTW, the RCA TT3 talks about "adequate shielding" for the 803 and suggests
an external shield that "should be designed to enclose the base end of the
tube and extend up to a position 1/4" above the circular shield disc located
at the bottom of the plate".  Of course, shielding is not quite as important
with swamped grid or gg.

Ed:

Thanks for the reply. I will take the case off and see if I can see a 
difference in the tube.

I don't do anything to get it to work again...it just does. I did neglect 
to say that once the scope fails to show output, it may continue to do so 
for several times at variable intervals when I turn it off and back on. 
Doesn't seem to be any pattern or combination to get it to work again. It 
just decides to. It might come on the next time I turn it on in a few 
seconds, or it might not come on for several times I try and turn it on for 
the next day, then it comes up like there was nothing wrong. Then its 
pretty consistent when it works.

Any test procedures or diagnostics on how I tell if the scope tube is 
getting proper power and signal? I have an oscilloscope and multimeter, so 
I can check each connection if I know what to look for.

Matt, KB8WFH



What I'd suggest....

When it's working, look at the CRT with everything in a dark room.  You
should see the filament.

Then, when it's not, do the same thing.  Since you have seen what it
looks like when it's working, you can see any difference when it's not.

How do you get it to work again?

Ed

Even if I leave it on for well over an hour, it never comes on. It only 
comes back on if I turn it off at some point and sometime turn it back on. 
Tapping the tube makes no difference. I have even opened it up and tried 
CAREFULLY  rotating and push/pulling the tube slightly to see if it makes 
any difference. It doesn't.

For example, I tried turning it on this morning and it worked perfectly. 
When it works, it never fails while it is on. However, this afternoon 
around 5:30, I tried it again, and nothing. I tried turning it off/on 
tapping/jiggling the tube and nothing. I opened it up to measure the 
voltage coming into the filament and when I turned it on, it still didn't 
work. I turned it off and back on, and suddenly, its back working. Hmm.

Yes, I have a schematic, thanks.

I have tested the filament connections and it registers 6.64 volts (ac) if 
the scope tube puts out a signal or not. I don't see any specs in my 
schematic indicating what it should be, although that sounds about right. I 
really don't see any signs what so ever of failed solders to the socket, 
but I will double-check.

I have to take the metal shield off the tube to see if if it lights up or 
not. Does that sleeve really need to be there for proper operation?

Thanks.

The tube filament clearly glows when it works and if the filament voltage

Hi Matt,


I have one which exhibits the same problem.  I traced it to the CRT
socket.  Removing and reconnecting the socket fixed it for a while,
but it has recently started up again showing the same symptom.  I
believe that the filament voltage to the CRT is being interrupted by
environmentally induced corrosion on the socket contacts along with 30
years of temperature cycles and resulting degradation of the
"spring" in the formed socket contacts. Next available time, I
intend to take the bull by the horns and remove the socket again, clean
the socket contacts (and the CRT pins) with Deoxit, and squeeze the
socket contacts a little with the needle nose pliers before reconnection
to the tube.  H opefully this will improve the connection and
correct the problem for another 30 (40?...) years......

You can also do as I did with my 4-1625's linear (grid driven). Use a
toroidal autotransformer to step up 50 ohms to 200 or whatever you want.
load the output with a noniductive resistor as mentioned above.

interesting, can slip in any tube in the hole, 805, 803, any 10 volt
tube, i have a 6AX4 low voltage (70v) bias supply to drive the grids into
cutoff

Some stuff on the 803:

- About 1971, there was an article in QST under the title "The Junker 
Amplifier" or some such. Classic W1ICP stuff. Basic GG amp using your choice of three 
tubes: 813, pair 811As, and the 803. TV transformer/voltage doubler supply.  
Good reading for ideas. 

The full-ratings limit for the 803 is only 20 Mc., and McCoy reported that 
efficiency and output were down on 15 and 10 with the 803. So if you want 15 and 
10, other tubes might be a better choice, but for 160/80/40/20 it's a rugged 
bottle. Looking at the data sheets, I wonder if the 813 wasn't a direct 
descendant of the 803.

 There was a 2 x 803 GG amp described in several editions of the "Radio Handbook" (west coast hb). As I recall, no grid bias was required.

Yep, you broke the code, Dave, that's how they all were made.  Burgess
Battery was here where I live, and they made millions of 'em.  They made
various standard sizes of Leclanche (zinc carbon) cells

http://www.geocities.com/bioelectrochemistry/leclanche.htm
http://rexlabs.dnsalias.net/chemproject/zinc-car.htm

and connected them in series to make the various B and combination A/B/C
batteries.  I don't know if they used solder or welding, or maybe both but
the tar is right.  I had the chance to tour the old factory once before it
was torn down and every surface was impregnated with carbon black.
Between that, the electrolyte, and the tar it was a nasty business.
Burgess failed to respond to the emerging alkaline cell and paid the
ultimate price.

Use some UF4007 diodes.  35 nSec recovery time.  1 KV PRV.  Cheap.  I'm

Subject: Re: GB> End of Daylight Saving

In Indiana only 6 counties go on daylight savings
time!  There are 3 at the northwestern end and three
at the southwestern end.  Those 6 counties are in the
Central time zone.  The rest of the state is on
Eastern time.

Thus, for 6 months the entire state is on the same
time and for 6 months those 6 counties are behind one
hour!

To make things even worse, in 1958 the State of
Indiana made the school districts that had less than a
certain number of students in the high school
consolidate with other districts until that minimum
was met.  Thus, many of the township schools that had
existed for decades had to consolidate with other
townships or else with the city schools nearby.

The state, in its infinite wisdom, chose to combine
the New Carlisle School District with the Rolling
Prairie School District.  Unfortunately, although
these two school districts were in different counties
(Rolling Prairie School District is in LaPorte County
and the New Carlisle School District is in St. Joseph
County) they are also located in different time zones!

The result is that when school starts in the late
summer everyone is on the same time.  Then, when
daylight savings time goes away, things like "school
starts at 7:30 Central and 8:30 Eastern, the dance
will begin at 6:30 Central and 7:30 Eastern", etc.,
becomes the norm.  Finally, when daylight savings time
comes back in the Spring, then things go back to the
same time!  It can get very confusing!

There are signs on the county roads at the county line
which not only say that you are entering the next
county, but also that the time zone changes!

As far as a gg amp goes, that's pretty much a true thing!

But the beauty of the L-net & swamped grid or autoxfmr & swamped grid with
the 803 is that you would have a fairly simple, but stable amplifier with
higher power gain than gg, but still without requiring neutralization.  The
805 or other triodes on the other hand, would still very likely require
neutralization in this type of circuit.

Shoot, 27C is just a cool, Spring day, in the Dallas,
Texas, area.  38C (just over 100F) is a warm day. 
Besides, as the Texas Aggies say when someone
complains about a hot day, "just wait until 1980"! 
That was the year of 100 days of 100F (at least at the
"old" weather station at Love Field) it did drop to 99
as a high at the "new" weather station at the DFW
Airport a couple of times!  The 100F days started on
June 1 and didn't end until September!

There were several days when the low temperature was
well over 100F!

Now, my middle daughter moved to Scottsdale, Arizona,
last year.  They have already had temperatures in
excess of 100F this month!

When I was in college at Georgia Tech in Atlanta, you
could always tell the students from Miami.  When the
temperature dropped below 70F they put on overcoats!

Then, again, I am a lot more comfortable in the Dallas
area when the temperature is over 100F than when I
lived in northwestern Indiana.  In the summer the
temperature often gets to 95F with at least 95%
humidity!  The same high humidity down around Houston.
 Now, that is "hot"!

Subject: GB> AA4/5, radio nutz, Hot Chassis Warning, monkey business

Is Monkey business conducted in Banannas?

Back when I was first exposed to 'real' computers at Ga Tech in 1971
we ran card decks through an old Cyber something or other (CDC?).
To account for machine time the computer center used these things
called 'banannas'. One could use up an entire quarters worth of banannas
with a small loop error. Slipping the procrastinator a 'bogus' card in
his 'borrowed' deck would qualify as monkey business, right?

Buddy Ed who is helping me with BAMA mirror and mailing list stuff wanted
a short wave radio to play with. Figured I'd start him on somethign basic
so fixed up a Hallicrafters S-120 today. He mentioned a 'line out' so I
suggested a coupling transformer from an old modem.

The headphone jack switches 8 Ohm speaker out to phones. Figured a plug
wired with 1W 8 Ohm resistor and the coupling transformer will do the
trick. Nothing else on the line so I don't have to worry about the 8 Ohm R
loading the line down. About 1/4W audo should give him is volt for line
out. Sound like a suitable ticket?

Made him a copy of the manual and noted, "This radio can KILL you!".
Pointed out AC line to chassis connection on the schema.

The old S-120 had been languishing in the attic for years. It hummed a bit
so stuffed a couple of old PeeCee power supply caps and a NOS cathode
bypass cap on the 50C5, cleaned the bandswitch and tune/bandspread cap
wipers, and it works like a champ. Takes a good minute to come up though.
Total C is almost 1000 mfd. 500 mfd is on the output tube screen and has
to charge through a 1k resistor.

I wanted to look at curves for 50C5 to see how screen I affected plate I
and ran across a mess of interesting stuff. Read on and you'll be snarfing
up those 50 cent yard sale aa4/5 clock radios.

The first find was better than the 50C5 curves which weren't there. Talks
about subbing 12BA7 for 12BE6 for more sensitivity. What do you guys
think?

http://www.geocities.com/CapeCanaveral/9178/radios/12ba7.html#12ba7

Doesn't really fit the "optimum receiver" discussion we'd been onto for a
while, but I'm trying to get Ed more interested in radio while he's doing
the same for me with LInux. Figured the S-120 would be a good place for
him to start. Will scrounge him an isolation transformer if he decides to
mess with hotrodding it.

Here's another page on AA4/5 mods...
http://home.netcom.com/~wa2ise/radios/compaa3.html

And more by same guy with cool hack on transistor radio improvement using
old PeeCee parts!

http://home.netcom.com/~wa2ise/radios/AA5submini.html

And here is an interesting site. Look at the past magazine articles.
http://www.amfone.net/

One guy mentions
"My first real transmitter was a Knight kit broadcaster kit. This
transmitter had a 50C5 oscillator final and another 50C5 heising modulator
with a 12AX7 microphonium preamp." and then goes on to describe
improvements...This is in issue 109.

Finally found the 50C5 curves here :-)

DST is great. Wish we had it year round. I love to get up in the AM and

With DST, I can do this at a 'reasonable' hour. Without DST, I have to get

It's very inefficient :-)

I have not been following the thread...yet... But, as far as neutralization in 
transmitters is concerned, perhaps I can help. I am not sure you can find a 
really good discussion of this on the web. However, I have found that 
practically any issue of the RCA Transmitting Tube Manual, TT-3, or TT-4 
especially, has an excellent discussion of this, and also of parasitic 
oscillations and how to cure them. I bought my copies on eBay.

Basically, in as few words as possible, neutralization concerns "neutralizing" 
the plate-to-grid capacitance of an amplifier tube, which can cause unwanted 
oscillations to occur. 

This plate-to-grid capacitance is, of course, much greater in triodes, than in 
tetrodes or pentodes, but, nonetheless, must be taken into account in circuits 
which use "high-sensitivity" types i.e. 6146, and others like those.

There are several common methods for neutralizing a circuit, but not all are 
equally effective, some only being really effective at one frequency, not over 
a band, or several bands.

One common way to neutralize a single-tube triode amp is to use a balanced 
plate circuit such as you would use for a push-pull type of circuit, and 
connect the end of the plate coil which is NOT connected to the tube plate, 
through a small variable capacitor (whose maximum value should be slighty 
greater than the tube plate-to-grid capacitance) directly back to the grid, then 
adjusting it for minimum feed through of the driving signal with no plate 
voltage connected to the amp.

Since RF energy at the end of the plate coil which is not connected to the 
plate is exactly 180 degrees out of phase with the plate end, its energy can 
be used to cancel the in-phase energy coupled internally across the tube 
from the plate to the grid due to the plate-to-grid capacitance.

This is called "plate neutralization".  There are other methods.

I hope this helps.

Subject: RE: GB> Neutralization...

Excellent description from what I understand Ken.

One op explained the concept too was confused by how we could "neutralize
the grid-plate capacitance". We don't, of course. What we are doing is
providing an out-of-phase feedback path identical to the grid-plate
capacitance feedback path. The out-of-phase feedback path, when it is set
properly, ensures that no signal gets coupled from the plate back to the
grid. For every millivolt of signal that's coupled through the grid-plate
capacitance, an equal millivolt out of phase is coupled back through the
neutralizing circuit. So the net feedback stays zero and the tube doesn't
oscillate.

Hey, in late 1966 that old syntex machine in the
computer building (the one that you had to run your
cards before "they" would let you run your program on
the Burrough's B-5500) used to play 5200 pickup
several times a night with the punch cards.  That is
why everyone soon learned to make at least 10 sets of
cards for anything that they ran through.

You know what "52 pickup" is with a deck of playing
cards, don't you?  Well, the machine would throw about
5200 cards into the air every hour, or so, mixing your
punch cards with everyone else's!

Then, the people running the unit would sweep the
floor, insert some more punch cards, and start again!

Hi Bob,

	Cyber 7600, or perhaps, the 6600 ( we had S/N 6 and 43 ) ? 

	I coop-ed my way though college supporting some huge classified
simulation programs run on those at the Air Force Weapons Lab in

Error handling? Ha! Just a dump of the registers and pertinent

One of the "problems" that we had was to write a
payroll program for the B-5500 that took care of
things like ending the FICA deduction after it reached
$4800 (remember, this was in 1966 when there "was" an
end to Social Security deductions!) and we had to put
in 6 weeks of "payroll" data for 4 employees.  Of
course with only 6 weeks of data the program wouldn't
get up to the point at which the deduction stopped. 
However, the professor could look at the program and
tell if it would have worked.

Unfortunately, or maybe fortunately, one of the data
cards on my program got "stuck" in the reader and the
computer kept reading the data over and over and over.
 The result was instead of 6 weeks of data being
entered, the computer printed out over 150 sheets of
data before an operator "caught" the card problem and
ended the program.  However, the ending of the
deduction portion of the program did work!  of course
the "employee" worked for several thousand weeks from
the data that was entered!

Also, a card got mixed into my cards from someone
else's program (by one of the student assistants in
the computer center) and somehow all my data was
"printed out" to tape and the program itself as well
as to the "hard copy" printer.  As far as I know, no
one ever discovered just where in the tapes that the
information got to.  They just knew that it got there!

Good idea, I'm going to put a pack together.  If you know anyone who does
electronic maintenance for a hospital, become their friend.  Medical devices
like infusion pumps and telemetry systems use 12 volt gel cells and they are
periodically replaced.  A buddy of mine gets them and sell them at hamfests
for a couple of dollars and there's nothing wrong with them.  Size ia about
3" by 6" and about 1" thick so a 48 volt pack would be reasonably small.

You kids! 

My first computer was the Rice Machine, at Rice University, a copy 
of the Whirlwind, with improvements. It used Williams-tube storage:
a charge got painted on a piece of a CRT for a "1", no charge for a 
"0", and it was _s_l_o_w_. Then the IBM 1620 and IBM 7040 at Rice,
followed by the CDC 3200, CDC 3600, and CDC 3800 (S/N #1) in the Data
Reduction Complex at the Manned Spacecraft Centre outside Houston. 

THe CDC stuff ran the SCOPE operating system, and we wrote and ran 
programs in Fortran, Compass (assembler) and NELIAC (Naval Electronics
Labs International Algol Compiler). This was back before 1967: I 
worked the last Mercury mission, all the Gemini missions, and the fire
in the Apollo I spacecraft. 

Fortran is still in use, of course, but so is NELIAC. 

Glowbug content: One of our two CDC 3200s had a craphics display 
                 station with a CRT.

I don't see how a battery pack like this could support the filament drain, 
which had to be around 250 mA, for a whole year. B batts, yes, since the
drain was only a few mA.  The cost of B batteries, it has dawned on me, 
could be a major cost to oldtime radio users. For an extreme example, you
might buy a minimal 1 tube radio kit from a magazine in the 1930s, for 
maybe $3-5, but then you'd need a battery almost as expensive.

I have taken B batts apart also, but it seems to me that the older ones (and
maybe the really high voltage ones still ) were made in layers of stacked flat
cells, like in the little 9v radio batteries.

I work for a Telco and we still buy 45 volt batteries. These seem to be a 
special type as regards connector and industrial label. They are used in
a "burn set" which stacks them up to about 600 volt ( i have been
told; i don't use the thing). When a copper cable section develops a leakage
resistance this high voltage is applied to the end of the cable pair; the 
leakage resistance spot breaks down and develops a hard short; and this
is easier to exactly locate than the leakage itself. At least that's my under-
standing of how it works. This process isn't used very often so the turn-
over in batteries is very, very slow, but i have scrounged some discards,
and they work fine for the low requirements of small tube QRP receivers.

I heard a story once from an outside technician who worked back East Coast
in some major urban area. They were checking out some phone wiring in
an apartment building, probably looking for pair assignments or following
up on some customer complaint, when they found that one neighbor had 
somehow tapped onto another apartment's line for free phone service. 
The techs isolated the tapper's line and connected the breakdown set to
it with 600 volt applied.  ( Not legal or safe, and the two would have been
canned if management found out.)  Anway they were around the building
for a good while still, woking, , when  some renter approached them in the halls, 
saying that his phone had had some really serious problem occur to it. They
declined to take any interest - not their department.

was room for something like 20 - 25 flashlight batteries, which were soldered
end to end with short wire jumpers. ( So i suppose you could call this
a portable. ) Also the joining jumpers went to a multiposition switch so
you could select the B+ voltage for best sensitivity of the gridleak

In Indiana only 6 counties go on daylight savings
time!  There are 3 at the northwestern end and three
at the southwestern end.  Those 6 counties are in the
Central time zone.  The rest of the state is on
Eastern time.

Thus, for 6 months the entire state is on the same
time and for 6 months those 6 counties are behind one
hour!

To make things even worse, in 1958 the State of
Indiana made the school districts that had less than a
certain number of students in the high school
consolidate with other districts until that minimum
was met.  Thus, many of the township schools that had
existed for decades had to consolidate with other
townships or else with the city schools nearby.

The state, in its infinite wisdom, chose to combine
the New Carlisle School District with the Rolling
Prairie School District.  Unfortunately, although
these two school districts were in different counties
(Rolling Prairie School District is in LaPorte County
and the New Carlisle School District is in St. Joseph
County) they are also located in different time zones!

The result is that when school starts in the late
summer everyone is on the same time.  Then, when
daylight savings time goes away, things like "school
starts at 7:30 Central and 8:30 Eastern, the dance
will begin at 6:30 Central and 7:30 Eastern", etc.,
becomes the norm.  Finally, when daylight savings time
comes back in the Spring, then things go back to the
same time!  It can get very confusing!

There are signs on the county roads at the county line
which not only say that you are entering the next
county, but also that the time zone changes!

The 1948 and 1949 ARRL Handbooks list battery data for some A and B 
batteries. There's one model spec'd to deliver 250 mA for 1200 hours if used 3-4 hours 
per day. Weighed something like 11 pounds! 

Some years back, NR5Q did an article in Electric Radio where he recalled the 
economics of "farm" radios and their batteries. IIRC, the batteries were not 
very expensive, nor were the sets. The batteries were specifically designed for 
a particular set's demand so that the A and B sections would wear out 
together. Of course when rural electrification came along, the battery sets were 
quickly replaced. 

In the 1930s, a special type of A battery called the "Air Cell" was 
developed. It developed a nominal 2 volts and had enormous capacity at low cost. It was 
shipped dry, and activated by removing a cover and pouring water into the 
cell. (It wasn't a dry battery, of course, and could be spilled). Special tubes 
whose filament characteristics matched the Air Cell were made.

 By the way, when I stated that the tubes were operated at "zero bias", I should have mentioned that were triode connected.

There's an interesting book entitled "Sleep Thieves" by Coren(?) which
describes an interesting correlation in traffic accidents with DST. Accident
rates spike the day after DST kicks in, and plunge on the day after it reverts
to EST. Apparently, the amount of sleep most people need is one hour more.

Well, actually the ancient Greeks *did* have an equivalent. It's not well 
known, but Alexander the Great,
besides being a military genius, was also an inventor. When he realized 
that complex maneuvers
depended on synchronism, Alexander experimented with a mixture solutions of 
chemicals that would
change color after a relatively precise interval. Strips of cloth dipped in 
the mixture and tied around
the wrist became known as "Alexander's Rag Time Band"....

Hi Dan,

The telephone industry has run on 48 volts for years.  Much of the 
telephone test equipment was also designed for 48 volts.  Take a look on 
the Internet for telco suppliers; I'll bet there are rechargeable 48 volt 
batteries and chargers to match them.  Also try the surplus industry.

Hi Dan,

The telephone industry has run on 48 volts for years.  Much of the 
telephone test equipment was also designed for 48 volts.  Take a look on 
the Internet for telco suppliers; I'll bet there are rechargeable 48 volt 
batteries and chargers to match them.  Also try the surplus industry.

I remember SCOPE. But, I'm not a computer guy. I couldn't deal with the
discipline :-)

Any of you guys know Dave Black? He runs a company called Cobol
Conversions and was with IBM back when the computers were hollowstate.
