Article: 99937 of rec.radio.amateur.boatanchors From: dplatt@radagast.org (Dave Platt) Subject: Edmund Laport "Radio Antenna Engineering" now in paperback edition Date: Tue, 20 Sep 2005 06:22:39 -0000 Message-ID: <11ivalf2vitoob2@corp.supernews.com> Back in May, I announced the availability of an electronic (PDF) edition of Edmund Laport's 1952 text "Radio Antenna Engineering", which I'd created by scanning a copy of the book after I confirmed that the original copyright had expired. The reaction to this has been quite satisfying - it's been downloaded over 200 times via my BitTorrent server, and at least as much more from one or another HTTP server. A few weeks ago, I received an excellent suggestion from Ed KI4AGL. He proposed that I upload the PDF to LuLu.com, a "publish and print on demand" company, so that people who wanted a hardcopy of this book could purchase one conveniently. I hadn't heard of LuLu, so I checked them out, and was impressed by what I saw. It turned out to be quite easy to set up an account, upload a slightly-tweaked version of the book's PDF, create a cover for it, and make it available to purchasers. Ed ordered one, and wrote me yesterday to say that it has arrived and that it looks good - the text and pictures all came out clearly. LuLu describes their product as being "bookstore-quality paperbacks" and from Ed's report it sounds like that's a fair description. As published through LuLu, "Radio Antenna Engineering" is a 6-by-9- inch softcover, printed on 60-pound paper stock, with a glued-edge "perfect binding". It's what's usually called a "trade paperback" edition, the same size as the original hardcover edition, and has all of the text and drawings and photographs. The large foldout map of the continental United States, with diagrams of the coverage patterns of certain MF broadcast stations, has been reduced down to fit on a single 6-by-9 page. The price for the book is set by LuLu - they charge by the page and add a flat fee for the binding. I published it using LuLu's "no royalty, no commission" service, which they've set up specifically to encourage people to keep obscure material in print. Postage is additional, depending on how you choose to have it shipped. With basic (media-mail) postal delivery in the U.S., the book comes to a bit less than $20. You can order it from: http://www.lulu.com/content/159004 I've added this information and link to my page at http://snulbug.mtview.ca.us/books/RadioAntennaEngineering/ on which you can find the BitTorrent download files, and links to an HTTP server which has the PDFs available. -- Dave Platt AE6EO Hosting the Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads!

But, with the oscillator fundamental at 7,825 kHz, the receiver will = receive both 14,000 kHz and, even better, 9,475 kHz, unless the RF stage = provides a sufficient block for the latter frequency. =20 Unfortunately, in Europe we have terrific BC signals in the 9.5-MHz = range, that pass through the receiver RF stage tuned coils, = independently of the frequency they are tuned at. Problem is that their = ultimate rejection is too low, and peaking the preselector does not help = at all. 73 Tony, I0JX Article: 99955 of rec.radio.amateur.boatanchors From: "Charlie Hugg" Subject: FS NIB Matched Pair of 8122 Tubes Message-ID: Date: Wed, 21 Sep 2005 16:30:38 -0500 I have for sale a set of New, Matched 8122 Tubes in original boxes and packing.

Yes, I'm being a bit flippant but hear me out. One of the concepts of an auction is to toss a piece out there as a means of unloading it and let the market decide what its worth...or at least facilitate them to get into a bidding war if there is more than one interested party. A 'retail' price tag on a rig that a reputable radio guy is unable to repair is a death blow to a sale. I don't think your $99 expectation for a hosed up SX-122 is an unreasonable goal. But that sounds more like an ending price than a starting price. Me? If I wanted to sell it and clear space in the shack I'd list it with a frank opinion that its screwed up beyond hopeful, simple repairs for 0.01 and let the market do its work. From my experience that works better than "I want $100 for a radio that I deem as unrepairable". Its a selling psychology thing, ya know...not a personal affront. -Bill Article: 99960 of rec.radio.amateur.boatanchors Date: Wed, 21 Sep 2005 22:47:02 -0400 From: Bill Subject: Re: Little chief capacitors References: <1127354331.883983.12500@g44g2000cwa.googlegroups.com> Message-ID: yzordderrex@verizon.net wrote: > I have a Hallicrafters SX110 on the operating table behind me.

I have an original SX-101A manual, which I presume should be the same as = the BAMA copy. Could you please tell me at which page you read that? In = my manual I was unable to find any mention of the oscillator frequency. I am pretty sure of the oscillator frequencies, as I measured them both = with a frequency meter and with an oscilloscope (the oscillator waveform = period on 20 meters is somewhat longer than on 40 meters, no question = about that). And the strong 9.5 MHz phantoms frequencies are exactly = what they should be with an halved oscillator frequency. On the other hand my receiver was owned by a person who never put his = hands in it, but even hypothesizing that someone did something in it, = what could he have done to make the oscillator frequency exactly half of = what one would expect to be, and on 10, 15 and 20 meters only? Halving = the oscillator frequency would cause the dial scale to be no longer = correct; matching is instead fairly good (with normal tolerances for a = receiver of that kind). 73 Tony I0JX / K0JX Article: 99965 of rec.radio.amateur.boatanchors From: "Antonio Vernucci" References: <1126565895.687794.194290@f14g2000cwb.googlegroups.com> <43321356.6020503@adelphia.net> Subject: Re: Advice on SX-101A Message-ID: Date: Thu, 22 Sep 2005 22:58:53 GMT Roger, I carefully re-checked the manual and I found the text you mentioned. It literally reads: "The 1st conversion oscillator operates at a = frequency higher than the incoming signal by an amount equal to the = first intermediate frequency of 1650 kc/s" That sentence clearly states that the beat frequency is higher than that = of the incoming RF signal but, in my opinion, it does not absolutely = also imply that the beat frequency corresponds to the fundamental = oscillator frequency. In other words, it is true that the beat frequency is always higher than = the incoming RF signal, but the beat frequency could be obtained by = taking the second harmonic of the oscillator frequency. And the sentence = would still be meaningful. I am taking that interpretation as I am 101% sure that, on 10, 15 and 20 = meters, the beat frequency is twice the fundamental oscillator = frequency. 73 Tony, I0JX=20 Article: 99966 of rec.radio.amateur.boatanchors From: Bob Miller Subject: Re: need QST archives from beginning to transistors era Message-ID: References: <1126855093.569254.226690@g43g2000cwa.googlegroups.com> Date: Fri, 23 Sep 2005 00:00:42 GMT On Thu, 22 Sep 2005 11:56:07 -0400, Bill wrote: >Bob Miller wrote: > >> go to http://www.arrl.org/ >> >> and enter the search term >> >> regenerative receiver >> >> there are 164 articles, most of which you can look at, whether you're >> an arrl member or not >> >> bob >> k5qwg >> >> >> > >Theres only two or three articles available that actually are about >regenerative receivers. > >-Bill I counted 5 or 6 how to build articles at the ARRL site. Or, go to Google and enter "How to build a regenerative receiver" and there are many more articles. In addition, my 1958 ARRL Handbook also has an article on a one-tube regenerative receiver. I imagine you can find that in any of the older handbooks that are on Ebay for a couple of dollars.

In summary, what I am trying to say for the sake of justifying what I = measure here is that the sentence "the oscillator frequency is always = higher than the signal frequency" should have been more precisely = written "the frequency used to convert the incoming RF signal to IF is = always higher than that of the RF signal". In this way the sentence = would become compatible with using the second harmonic of the oscillator = for converting the RF signal (on 20 meters the measured fundamental = oscillator frequency is lower than the RF signal, but its second = harmonic is anyway higher). Anyway, I agree with you that using the second harmonic of the = oscillator is rather odd, but it is a fact that, in addition to the = frequency meter and the oscilloscope measurement results, the phantom = carriers coming from the 9.5 MHz band are exactly where they should be = if the second oscillator harmonic is used. It looks like a kind of a mistery. I hope that an SX101A owner will take = care to measure the oscillator frequency at his first convenient = occasion. 73 Tony, I0JX the SX-101A, the frequency that converts the RF signal into the IF = signal is always higher than the RF signal. This is absoultely true, on = the other hand the receiver dial shows the same sense on all bands (if, = on a certain band, the frequency that converts the RF signal into the IF = signal would be lower than the RF signal, then the relevant dial would = go in the opposite direction).

Perhaps the stability of 30 MHz = oscillator is, in practice, more than twice worse than that of a 15 MHz = oscillator, so they preferred to work at lower frequency and take the = second harmonic.
