That's not too far off. :) We're all somewhat mislead by the assumed complexity. After all that we've read and thought, it's not easy to accept on faith that reflowing doesn't have to require carefully controlled equipment and expensive stencils. For now, consider only that hand soldering is much more stressful to the parts than almost any other (mis)treatment. Uneven heating; uncertain temperature rise; solder bridging and subsequent rework and more heat stress; ... on and on. On that basis alone, stir-frying is already a huge improvement. At its best, it isn't very far from a more stringently controlled process. A few pictures of it working will help make the point. I had every intention at the onset of taking a few, and plotting temperatures taken with an IR thermometer. After doing the first board, though, the whole process seemed as obvious as noting that a rock will indeed drive nails. Or something like that. Bear with me. The temperature profile is likely the major concern in your mind. Here's an example of a profile: http://www.stencilsunlimited.com/solder_products.php. Click on the link for "SynTECH Technical Data Sheet". The profile is on page 2. (Incidentally, their prices are among the lowest I found for small quantities. Less than $25 for a 35g syringe shipped. I use their 63/37 paste.) There are two important control points: flux activation at 140^C, and reflow at 220^C. Flux activation is easily recognizable by the gray crud that forms on the paste. Reflow is also obvious from visual cues: the paste turns silvery and looks like molten solder. All that's needed now is to control the time. Medium flame on my kitchen range is just about right for my thick bottomed aluminum skillet. Flux activation "happens" in a little less than 2 minutes. Reflow starts about 2 minutes later. When the last bit of paste turns silvery, cover the skillet, count to ten slowly, and then turn off the flame. Let it cool undisturbed. The rest of it is putting on the paste and populating the board. You don't need a stencil to do that. Just draw a neat bead along the pads. The parts center themselves when it reflows. Compare that to the contortions of holding an SOT23 in place to solder by hand. There is a difference in how you plan your work. Since you can reflow only once without special pastes and finer control, everything has to go on in the 6 hours the paste remains workable. The NorCal 2030 probably shouldn't be your first project. Anyway, stir frying works well and easily with very few critical details. Try it on a scrap board first to "calibrate" the stove. Within reason, a little too hot is better than not hot enough, and a little too much paste is better than not enough.

There's just the slightest curve on the bottom of the skillet so it sits on its corners. I don't believe this is critical. Direct contact on the face will probably work just as well. Components on the top-side only. You'll need to use a different paste if you need to reflow top and bottom, and definitely need tighter control on the temperature for the second side. An uncontrolled skillet won't do for that. Use a tin/silver paste for the first side. Its higher reflow temperature will allow you to reflow tin/lead on the second side. You'll want to use stand-offs in a properly controlled oven for that. > What else didn't I ask? Hot air is an alternative. I use a Weller Portasol with hot air nozzle for small rework. I hear of others replacing the rubber bulb on a Radio Shack desoldering iron with an aquarium pump. It takes longer to build a board, but might suit the pace of a homebrewer better. > I've seen the web sites showing how to do toaster-oven reflow -- have you > tried that? I haven't tried using a toaster oven. The concepts remain the same, however. There might be a difference between heating with IR elements and heating the board more or less directly.

They have always worked well for me and generally you can tell by looking at a tint whether it is metallic or not. They "look metallic" with a silver tint. I've not seen any of the tan, green, or brown tints that were metallic. I ran a TM-D700 and a TM-V7A running 50 watts on 144 to these with no problems. They didn't seem to mind the higher SWR on 440 and did well there too.

Wow, memories again! :) Bought one for my daughter about 25 years ago. Though she's been grown and gone for a good while, it's still intact and sitting on the top shelf of her closet (her closet here). Just looked at it - it's a 150 in 1.

Figured out that if he wanted to know if it was raining, all he had to do was put it together, carry it outside, hold it up for a while, and bingo!

Yes, maybe they can program something on a computer to do that - but they should try tackling the "component" level stuff. Actually learn what it takes to do all that. There are probably a host of reasons we could bring up as to "why" they don't - but it doesn't necessarily have to be that way. Even miniaturization goes so far...... if the demand for the larger parts such as we're used to working with would increase - maybe the action would pick back up. As to the kits and Radio Shack, I learned from their books. My father bought me like a 50 in 1 kit from Lafayette Radio - I think! Back then, Radio Shack hadn't gotten in our area yet. BUT then when they did, I bought every book they had. I've had technical training since then and went beyond that. I build items from junk parts just to have something to do when not repairing. It is a very enjoyable hobby. I went to a Hamfest this past summer and someone gave me a 150 in 1 kit with a book. I have other items here which have power strips and so on - but you have to supply the parts yourself. But still - makes for a lot of designing fun.

I was "trying" to give them the benefit of doubt. Chemistry sets - eh? Man, my bedroom was a mini lab. If I had now - what I had then - they'd arrest me on suspicion of a Meth Lab or something. Man, I had a telescope, microscope, geology set, chemistry set, jars of formaldehyde (sp?) with specimens in it, and so on. Not to mention the electronics crap I had a ton of. I barely had room for my clothes, bed and other eh - more important stuff. Ya know - looking back - I miss all that........ That was FUN...... Half the so called Chemistry sets and so on now - don't have half the goodies the sets did back then. These new sets are garbage compared to what we used to get. Same with the new project kits. JUNK....... Knowing what we had, maybe there is a reason these kids would be bored. Somewhere, I think I have a couple pictures of my Lab - er - I mean Bedroom.

(Mixer output is a SA602 and IF input is SA605). The mixer output is around 1500 Ohms and the IF input is around 4500 Ohms with 2.5pF capacitance parallel. The required source and termination for the filter is 800 Ohms par with 3pF. The insertion loss of the filter is 2dB max. Would the impedances be close enough to use resitive pad between mixer and filter (680R in series with 1k2) and a small cap to ground across the filter input. Then a 980R resistor to ground at filter output and no capacitance (use SA605 2.5pF and stray to make up the 3pF). This would give total loss around 4.7dB. Or would I be better to use say a tapped capacitor or L match from Mixer to filter with added C on filter input. Apparently the SA605 has a "swet spot" for noise at around 800R so maybe the Res to ground on the input would be ideal ??? Thanks for any help, I have not used crystal filters before and unsure of implications of the approach. Regards David Huisman Article: 96153 of rec.radio.amateur.homebrew From: "William E. Sabin" References: Subject: Re: Crystal Filter Matching Message-ID: Date: Sun, 15 Jan 2006 12:29:03 GMT Xtal filters are designed to operate correctly between specific values of generator and load resistances. Trying to "match" the input and output impedances almost always degrades the filter frequency response. Xtal filters are rather strange in that respect because of the complicated things that go on inside. Transforming the generator and load resistances to 800 ohms using L networks is an excellent idea. Add the 3 pF that the vendor suggests.

My hobby began in 1973 when I got a Thomas Salter Electrical Lab 4 for Christmas. I got one of these 150-in-1 IC experimenters kits for Christmas in 1974: http://www.transistor.org/collection/lafayette/lafayette4.html The UK version wasn't badged "Lafayette". Regrettably, I trashed it for the parts many years ago, although I still have the wooden case.

So you won't get anything like a DC step unless you are talking about very short durations. (Few msec or so.) Longer durations will have more and more noticeable tilt as the input coupling capacitors charge up. If you are only using this as an auditory stimulus click, say, for evoked potentials, it probaby won't make any difference because you couldn't really hear the DC anyway, just the transitions. But if you are trying to (say) drive a solenoid to whack a resonant structure, you will need some external interface. Tell us more about what you are trying to do.

I have no clue of the model number, but I think it had: one transistor, one diode, one variable coil (magnetic material on the end of a small threaded rod that went into the coil, you turn the end of the rod to 'tune' it - common then, I don't see them nowadays) several capacitors and resistors small crystal earphone I recall that it used small compression springs to accept the wires, and Fahnestock clips to connect to things off-board: earphone, antenna and ground. Or perhaps it used only springs, but Fahnestock clips were common connectors for these projects. There were two radio projects, one with the diode, and one with the transistor. The one with the transistor was of course much more sensitive and played louder through the earphone. I later recall having another brand, a 'more advanced' model on an actual printed circuit board (there were traces between each component's leads and the clips or springs on the board), perhaps it was a Knight-Kit. It had a relay, a silicon photocell, probably two transistors, and the usual passive components. > >Thanks > >TMT Article: 96165 of rec.radio.amateur.homebrew Subject: GOOGLE SECRETS ..earn easy money From: "J Dee" Date: Sun, 15 Jan 2006 13:51:29 -0600 Message-ID: <1137354689_4477@sp6iad.superfeed.net> I was browsing these newsgroups, just like you are now, and came across an article similar to this that said you could make thousands of CASH within weeks with only an initial investment of $6.00 plus stamps! So I thought, "Yeah, right, this must be a scam!" But like most of us I was curious and kept reading. It said that if you send $1.00 to each of the 6 names and addresses listed in the article, you could make thousands in a very short period of time. You then place your own name and address at the bottom of the list at #6, and post the article to at least 300 newsgroups. No catch, that was it. So I invested six $1.00 bills and six 32 cent postage stamps ... and boy am I glad I did!!! Within 7 days, I started getting CASH in the mail! I was shocked! I figured it would end soon and didn't give it another thought. But the CASH continued coming in. In my first week I made between $20 to $30. By the end of the second week I had a made a total of $1,000.00. In the third week I had over $10,000.00 and it was still growing. This is now my fourth week and I have made a total of just over $42,000 and it's still coming in ..... It's certainly worth $6.00 and 6 stamps !!! Also, make sure you print a copy of this article NOW, so you can get the information off of it as you need it. I promise you that if you follow the directions exactly, that you will start making more CASH than you thought possible by doing something so easy! Suggestion: Read this entire message carefully! (print it out or download it.) Follow the simple directions and watch the CASH come in! It's easy. It's legal. And, your investment is only $6.00 (Plus postage) IMPORTANT: This is not a rip-off; it is not indecent; it is not illegal; and it is virtually no risk - it really works!!!! If all of the following instructions are adhered to, you will receive extraordinary dividends. PLEASE NOTE: Please follow these directions EXACTLY, and $50,000 or more can be yours in 20 to 60 days. This program remains successful because of the honesty and integrity of the participants. Please continue its success by carefully adhering to the instructions. You will now become part of the Mail Order business. In this business your product is not solid and tangible, it's a service. You are in the business of developing Mailing Lists. Many large corporations are happy to pay big bucks for quality lists. However, the CASH made from the mailing lists is secondary to the income which is made from people like you and me asking to be included in that list. Here are the 4 easy steps to success: STEP 1: Get 6 separate pieces of paper and write the following on each piece of paper "PLEASE PUT ME ON YOUR MAILING LIST." Now get 6 US $1.00 bills and place ONE inside EACH of the 6 pieces of paper so the bill will not be seen through the envelope (to prevent thievery). Place one paper in each of the 6 envelopes and seal them. You should now have 6 sealed envelopes, each with a piece of paper stating the above phrase, your name and address, and a $1.00 bill. What you are doing is creating a service. THIS IS ABSOLUTELY LEGAL! You are requesting a legitimate service and you are paying for it! Mail the 6 envelopes to the following addresses: #1) Barry Hewison 1222 Louisa ST. Watertown WI 53098 #2) David Hall 19855 Deercreek DR. Zachary LA. 70791 #3) P Sewak 6 John Warren Avenue Glenwood NSW 2768 Australia #4) S James #34 - 7611 Moffatt Rd Richmond BC V6Y 1X9 Canada #5) J Johnson 201 Dames Road London E7 OEA England #6) S Wize 43A Portnall Road London W9 3BA United Kingdom STEP 2: Now take the #1 name off the list that you see above, move the other names up (6 becomes 5, 5 becomes 4, etc...) and add YOUR Name as number 6 on the list. STEP 3: Change anything you need to, but try to keep this article as close to original as possible. Now, post your amended article to at least 300 newsgroups. (I think there are close to 32,000 groups) All you need is 300, but remember, the more you post, the more CASH you make! Keep a copy of these steps for yourself and, whenever you need CASH, you can use it again, and again. PLEASE REMEMBER that this program remains successful because of the honesty and integrity of the participants and by their carefully adhering to the directions. Look at it this way. If you are a person of integrity, the program will continue and the CASH that so many others have received will come your way. NOTE: You may want to retain every name and address sent to you, either on a computer or hard copy and keep the notes people send you. This VERIFIES that you are truly providing a service. (Also, it might be a good idea to wrap the $1 bill in dark paper to reduce the risk of mail theft.) So, as each post is downloaded and the directions carefully followed, six members will be reimbursed for their participation as a List Developer with one dollar each. Your name will move up the list geometrically so that when your name reaches the #1 position you will be receiving thousands of CASH in CASH!!! What an opportunity for only $6.00 ($1.00 for each of the first six people listed above) Send it now, add your own name to the list and you're in business! DIRECTIONS FOR HOW TO POST TO NEWSGROUPS Step 1) You do not need to re-type this entire letter to do your own posting. Simply put your cursor at the beginning of this letter and drag your cursor to the bottom of this letter, and select 'copy' from the edit menu. This will copy the entire letter into the computer's memory. Step 2) Open a blank 'notepad' file and place your cursor at the top of the blank page. From the 'edit' menu select 'paste'. This will paste a copy of the letter into notepad so that you can add your name to the list. Step 3) Save your new notepad file as a .txt file. If you want to do your postings in different settings, you'll always have this file to go back to. Step 4) Use Netscape or Internet explorer and try searching for various newsgroups (on-line forums, message boards, chat sites, discussions.) Step 5) Visit these message boards and post this article as a new message by highlighting the text of this letter and selecting paste >from the edit menu. Fill in the Subject, this will be the header that everyone sees as they scroll through the list of postings in a particular group, click the post message button. You're done with your first one! Congratulations...THAT'S IT! All you have to do is jump to different newsgroups and post away, after you get the hang of it, it will take about 30 seconds for each newsgroup! REMEMBER, THE MORE NEWSGROUPS YOU POST IN, THE MORE CASH YOU WILL MAKE!! BUT YOU HAVE TO POST A MINIMUM OF 300 That's it! You will begin receiving CASH from around the world within days! You may eventually want to rent a P.O.Box due to the large amount of mail you will receive. If you wish to stay anonymous, you can invent a name to use, as long as the postman will deliver it. JUST MAKE SURE ALL THE ADDRESSES ARE CORRECT Now the WHY part: Out of 300 postings, say I receive only 7 replies (a very low example). So then I made $7.00 with my name at #6 on the letter. Now, each of the 7 persons who just sent me $1.00 make the MINIMUM 300 postings, each with my name at #5 and only 7 persons respond to each of the 7 original 7, that is another $49.00 for me, now those 49 each make 300 MINIMUM posts with my name at #4 and only 7 replies each, I will bring in an additional $343.00! Now, those 343 persons turn around and post the MINIMUM 300 with my name at #3 and only receive 7 replies each, I will make an additional $2401.00! OK, now here is the fun part, each of those 2401 persons post a MINIMUM 300 letters with my name at #2 and they each only receive 7 replies, that just made me $16,807.00!!! Those 16807 persons will all deliver this message to 300 newsgroups with my name at #1 and if still 7 persons per 300 Newsgroups react I will receive $117,649.00! With an original investment of only $6.00! And some stamps. AMAZING! When your name is no longer on the list, you just take the latest posting in the newsgroups, and send out another $6.00 to names on the list, putting your name at number 6 again. And start posting again. The thing to remember is: do you realize that thousands of people all over the world are joining the internet and reading these articles everyday? JUST LIKE YOU are now!! So, can you afford $6.00 and see if it really works?? I think so... People have said, "what if the plan is played out and no one sends you the CASH? So what! What are the chances of that happening when there are tons of new honest users and new honest people who are joining the internet and newsgroups everyday and are willing to give it a try? Estimates are at 20,000 to 50,000 new users, every day, with thousands of those joining the actual internet. Remember, play FAIRLY and HONESTLY and this will really work. ** By the way, if you try to deceive people by posting the messages with your name in the list and not sending the CASH to the rest of the people already on the list, you will NOT get as much. This is the fairest and most honest way I have ever seen to share the wealth of the world without costing anything but our time!!! You also may want to buy mailing and e-mail lists for future CASH. Make sure you print this article out RIGHT NOW! Also, try to keep a list of everyone that sends you CASH and always keep an eye on the newsgroups to make sure everyone is playing fairly. Remember, HONESTY IS THE BEST POLICY. You don't need to cheat the basic idea to make the CASH!! GOOD LUCK to all and please play fairly and reap the huge rewards from this, which is tons of extra CASH. Please remember to declare your extra income. Thanks once again... "People have asked me if this is really legal. Well, it is! You are using the Internet to advertise your business. What is that business? You are creating a mailing list of people who are interested in home based computer and online business and methods of generating income at home. Remember, people send you a small fee to be added to your mailing list. It is legal. What will you do with your list of thousands of names? That's up to you." So, build your mailing list, keep good accounts, declare the income and pay your taxes. By doing this you prove your business intentions. Keep an eye on the newsgroups and when the cash has stopped coming (that means your name is no longer on the list), you just take the latest posting at the newsgroups, send another $6.00 to the names stated on the list, make your corrections (put your name at #6) and start posting again. NOTES: *1. In some countries, the export of the country's exchange is illegal. But you can get the license to do this from the post office, explaining the above statements (that you have an online business, etc. You may have to pay an extra tax, but that's OK, the amount of the incoming CASH is HUGE! And as I said, a few countries have that restriction. *2. You may want to buy mailing and e-mail lists for future CASH. (Or Database or Spreadsheet software.) *3. If you're really not sure or still think this can't be for real, please print a copy of this article and give it to someone who really needs the CASH, and see what happens. *4. You will start getting responses within 1-2 weeks, it depends. ***ALSO REMEMBER*** SEND YOUR $1 OUT TO EVERYONE ON THE LIST, EVEN IF THEY ARE NOT FROM THE U.S. WHAT ARE YOU WAITING FOR???

I can't say 100%, but I've had good luck with the following techniques: 1. Use disks with a recording surface that looks yellow (aka "gold"). There are different dyes used and that seems to work the best. 2. Record at no faster than the read speed of the drive. 3. For some unexplained reason, the best luck I have had is with a DVD burner (I've done it with 3 different ones, LG, Toshiba and NEC) at single (CD 4x) speed. 4. Turn off any buffer overrun protection. It works by streching out the gap between sectors and the new gap may be too big for older drives. 5. Always make sure you finalize the disk, close the sessions, fixate (same thing different software). 6. A CD lens cleaning disk has saved many a drive for me. But I live in the desert. I've had great luck with TEAC blanks, they are marked 12x to 52x but they do work at lower speeds. Software issues: I often burn my CDs and DVD roms using a combination of UDF and ISO file systems. Older operating systems seem to have trouble with them, limit them to ISO file systems. If you really get stuck, try turning off rock-ridge and joliet extensions. Good luck, Geoff. -- Geoffrey S.

With the laws today - the parents would be arrested immediately - in most cases for Child Abuse - and questions asked later. The answer of trying to teach them electronics probably wouldn't be a good answer now days. Many of those who made and uphold the laws either didn't grow up like we did - or - lead a very sheltered life and took very few chances. It certainly wasn't my parents fault, I was a very inquisitive child. Hell, I stuck my fingers in empty light sockets and hit the switch and did many other stupd stunts - more than I can keep count of. But, I LEARNED. Back in those good ole days - Child Abuse may have been around, but parents weren't busted just for looking at their child - in a cross manner. THAT was living. Today - you have to watch anything and everything. I'm glad my kids are grown, now I don't have that worry.

Mention Foster-Seely to any of the other hams listening and they thought it was a mattress. One of them didn't know how to solder a resistor to a PC board ... afaik the others didn't even try.

Anyone have any experience with this? All operating systems do. There's not much to it. What you need is essentially a packet radio modem, and from there, TCP/IP over the air is not hard to do. You can't mix ham radio with the Internet because of the strict laws against commercial traffic on ham radio. But apart from that, it's a good thing, and very useful in emergencies. I don't do packet radio myself because it's too much like my day job, but it's certainly a popular part of ham radio.

My guess is sound to [somthing] >ratio? Standing wave ratio. It is a measure of how well (in this case) the antenna system accepts the energy sent to it up the transmission line and radiates it, compared to reflecting it back to the source transmitter. The transmission line should be 50 ohm coax in your case. If the tranmission line/system has serious impedance variation or discontinuity, power is reflected back to the source rather than passing along the line. As the through-glass coupling system employs frequency-sensitive tuned circuit elements, a substantial change in frequency as you suggest will certainly create a serious impedance discontinuity. Overall transmission efficiency pooter<-> antenna would be very poor as a result. You may well find that a decent 2.4G antenna on the pooter inside the vehicle is more efficient.

Almost all ham gear these days runs on 12 volts DC, so anywhere you have a running car, you can power it. Much of it is low-power and will run for a very long time on a car battery.

You get to (legally!) transmit on the HF bands where just a handful of watts can carry a message around the planet... that's still pretty darned cool. It's also a lot easier to find a free chunk-o-spectrum with a ham license if you just want to build a few transmitters or receivers than trying to do something on the ISM bands... and you get to use a lot more power. The average ham today probably does have far less "electronics" knowledge than one 50 years ago, although one has to keep in mind that 50 years ago it was a lot easier to have a lot of "deep" knowledge in many fields than it is today. Building something like a modern cell phone requires so much knowledge that you can't really begrudge the guy who implemented, e.g., the Viterbi decoder in some digital logic in some corner of an ASIC the fact that he doesn't know how to solder.

Additionally the military had plenty of their own infrastructure, which included satellite links. For the average person, I think the best thing hams can do in disaster areas these days is to set up a bunch of PCs that ship out short e-mail messages over HF using Winlink or similiar. If the hams can manage to get a reasonably high speed link to a functional hilltop repeater or similar going, setting up a WiFi gateway would be the way to go. I have a lot of mixed feelings about hams and emergency communications these days. The kind of things that emergency operations personnel expect in the way of communications these days tend to require a fair amount of fancy equipment and a lot of training. Investing that sort of funding into a "volunteer" group is not something that tends to go over very well anymore, unless it's a group such as, e.g., a volunteer fire department where there are strict duties and responsibilities spelled out and not just some "ad hoc" gathering of a bunch of guys at a pizza parlor every month. ---Joel Article: 96226 of rec.radio.amateur.homebrew From: "Andreu" Subject: LF Dip Meter Message-ID: Date: Wed, 18 Jan 2006 09:29:25 GMT I have several small measuring instruments in my shack, but I have always been unable to find plans to build a DIP METER for use in LF Freqs.

Millen used to make a set of LF coils that plugged into one of their GDOs without any modifications to the unit. It seems then that you simply need to make an appropriate coil (old wave-wound IF transformer coils perhaps) and to draw a calibration graph for it. I was thinking of doing just that but on the other hand, should anyone have a set of LF coils for sale for the 90652 or any information on them, I would be most interested.

Actually, depending on where you are coming from and what you are doing, Windows can be your friend.

If you put the tip in a dish of soap solution, you can get bubbles full of stoichiometric oxyacetylene mix, which make a pretty good _BANG_ when you light them.

The operation of the hardware is restricted to those who hold an appropriate license. Who may or may not elect to share the usefulness of that equipment with whoever he chooses. To suggest otherwise would be akin to laying claim that only those holding drivers licenses could be passengers in a car. Or that only a properly licensed electrician could make use of or enjoy electrical equipment. In turn most likely meaning that you couldn't operate your shack being that you're most likely not a licensed electrician.

My favorite Christmas present this last year was a basic electronics kit like the old RS (or Heath) ones I had as a kid. It was presented to me by my nine year old daughter...in the hopes that I would build the projects with her, of course. We spent an hour putting the kit together, built the first project; and then I turned her loose...thinking she would build the next most complicated one, and work her way up. The next day when I came home, she presented me with a working example of the most complicated device in the project book. We had a ball subbing in different components, and then explaining to her why they made the circuit operate differently. jak > > The Radio Shack here in town has closed.
