Sadly, most of those were hot chassis. However, a very interesting device is the microwave oven transformer. 110V in, 1KV out, varying from half a kilowatt to a kilowatt. The transformer core is split so you can easily take turns off to lower the secondary voltage, too. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis."

References: From: haynes@alumni.uark.edu (Jim Haynes) Message-ID: Date: Wed, 09 Nov 2005 03:13:52 GMT There was an article in Antique Radio Classified some years ago that made me aware of capacitors with tapered plates. You can look up that patent online www.uspto.gov, click on search under patents, click on patent number search, put in the number, and when it tells you click on images. You have to have a tiff viewer plugin in your web browser to read them. That particular patent seems to apply to a capacitor with flat plates, so perhaps there was a pending patent on the tapered plates. A variable capacitor with semicircular plates and the axis of rotation going through the middle and flat plates gives of course a linear relationship between capacitance and angular rotation. By altering the plate shape a bit and moving the axis of rotation off-center you can get a capacitor that tunes straight-line wavelength. Wavelength is proportional to the square root of capacitance. In the early days of radio wavelength was often specified instead of frequency. You can make a variable capacitor that is straight-line frequency, which rotation has to be proportional to the reciprocal of the square root of capacitance. With flat plates this requires a fairly radical plate shape, with the axis of rotation very far off center. As a result there has to be a lot of empty space for those long narrow plates to swing around. I'll post a picture of one of these to that binaries group. So a way to get around the odd plate shape and the space it occupies is to use plates of tapered thickness. It would be nice if you got straight-line something, but even if you don't you have something where the stations are more spread out than they are with straight line capacitance. I have an old TRF receiver of the vintage of multiple knobs and 01A tubes that uses capacitors like this. -- jhhaynes at earthlink dot net Article: 100551 of rec.radio.amateur.boatanchors From: "Steve NU0P" Subject: MARS Thunderbird Mobile Tansmitter Info Message-ID: Date: Wed, 09 Nov 2005 16:14:37 GMT I just acquired a Mars Thunderbird Mobile Tansmitter that uses a pari of 6AQ5 tubes and a 12AU7.

If the rig was simple enough, they might. And it was pretty normal for them to show snippets of the schematic, because there was something different about that bit of the circuit, and they wanted to talk about it. It's only in recent years that they dropped the any schematics >from the reviews. Given the description, I can't imagine the rig being particularly unusual. Look in old handbooks to find rigs with that tube arrangement, and you've got something close, which can be used to visualize the rig and use as a start for tracing the schematic or troubleshooting.

There is no manufacturer's name on it anywhere. And all the parts are from various well-known parts vendors (except no labels on the coils). There are several theories: Might be a home-built set - if so, it's incredibly well done, including an engraved front panel Might be built from a kit - but then you'd think the kit manufacturer would have put a name on it somewhere. Might be a factory-built set for some department-store chain that was to attach their own brand label, tho there is no evidence that one ever was attached. Might be a factory-built set and the maker is deliberately non-identified to avoid paying royalties on the Neutrodyne patents. Which could also apply to a kit. I read some early superhets were sold as kits to get around paying patent royalties. Someone suggested a fly-by-night manufacturer, who would come into a village with a wagon load of receivers, and secretly bring another wagon with a transmitter. The transmitter would assure they had a good signal while they were selling the receivers; and once they were all sold they could move on. However this receiver is certainly not shoddily constructed.

Wayne Hamfest Items Message-ID: Date: Sat, 12 Nov 2005 18:28:28 GMT Weather permitting I'll be going from Tulsa, OK to the Ft. Wayne Ind. hamfest on Nov. 18 & 19 as I've got to reduce my ham gear collection. I plan on bringing as many heavy items that I can get in the car because I don't want to eBay them as they're too much trouble to pack. I'll bring whatever I can that generates interest via this email. I'd like to rent a van but that's $150.00 more expense and I figure it'll cost me $500 to go! Most of the stuff has been in storage for about 10 years and most of it worked when put up. I haven't priced the stuff yet but I want to get as much as I can reasonably close to going market price, so I can get my expenses back. If I can't I'll bring it back and eBay the stuff. Here's what I have: Several Collins 75A-1, 75A-2, 75A-3 and 75A-4. A heavily moded 75A-4, A 30L-1, and 30S-1 but the 30S will take too much space. And a couple of R-390A and 651S-1 Drake L4B, L7, L75. Hammurlund HQ-170 I have 2, one has a clock, HQ-180 with clock Heathkit HL-2200, SB 220, SB-200, SS-9000 Hallicrafters SX-28, SX-62, HT-33B, R45/ARR-7 I have several 28s Gonset 3323 Swan linears Mark I, Mark II and 6B National NC-183D, NC-303, NC-400. Since I'm not getting a van I'll bring only 8 to 10 and try to maximze my cash. I plan to drive up in 2 days leaving Tulsa Nov. 17 and going via Springfield, MO, St. Louis, Indianapolis and Ft.

What it is with people who come here with an attitude, using a name that in effect sets the stage, "lazy senior", and seem not very good at asking questions, yet when they don't like the responses, they think the medium is at fault. YOu get interested in something, you read up on it. Then you ask the questions from the standpoint of having some sort of common basis with the people you are asking questions. A year before I was licensed, I had a basic idea of how oscilliscopes were used for modulation monitoring, and had an idea of what was commonly used. It was in the ARRL Handbook, and there was a time when virtually every ham would have had a copy, it being common ground. So then you would know the basics, and if you couldn't grasp some of what was said, then you could come here and say "I read up on oscilliscopes for modulation monitoring in the Handbook, but I still don't get why they connect directly to the deflection plates, rather than feeding it through the input on a commercial scope?". That question defines some of the issues, and ultimately it is a couple of hints to you, hinting that the answer was in at least the old Handbooks, hinting that the answer you seek. If you didn't have such contempt for the medium, this is the second time you've turned around after coming to us with your questions and said you don't like the medium, you might grasp that far more than a comment on your laziness, my bit about books was against the notion that the internet would be the final point of all information. It can be really useful for obscure bits of information that might not travel well because of limited appeal, but books and magazines with their more formal style are often the best place for learning. People who think they can have all the answers without going near books are fools. I would suggest there is something in the tone of your posts that causes the responses. But telling someone to read up on what you are interested in is not some "usenet" thing. Decades ago, people likely were directed to the Handbook for many an answer, because it had already been written. When I was a kid and newly licensed, the most important thing anyone told me was to keep reading all that I could get my hands on, and the most important thing was that they lent or gave me back issues of the ham magazines, and old books, so I could read and learn. Ask an interesting question, you are more likely to get a good response. Remember, people aren't paid to answer your questions here, so you have to give them reason to want to. Your "lazy senior" is a bad start, asking general questions that could best be answered by reading would be an issue too. And maybe, it's your attitude that you think you know the answer, but then want others to give you that same thought. When you asked about amplifiers, a little dip into the old books would tell you nobody used a linear in the days of AM. People told you that, people gave reasons why, but then you turned around and basically ignoring what was written, said "yeah, but what about linear amplifiers". In effect, what we took the time to write didn't matter to you, because you "knew" the answer was a linear amplifier. You can't learn anything if you don't listen to what people are saying. If you don't like my responses, you'd better be looking at yourself, because I've had access to the newsgroups since 1994, and it sure isn't so I can "ridicule" people. I'll go out of my way to write something if I feel the poster is worthy of the effort, but sometimes the truth is indeed that they should be reading books or even doing websearches.

It is fairly clean with some minor scratches under the meter. I fired it up and it put out around 100 watts so some new caps and maybe a set of finals would be in order. The wiring looks clean. The cabinet looks like a repaint but good. I am asking $425 which is what I paid for it including a copy of the manual. I did pick up a pair of 3B28's for it but never got that far. This guy is too big to ship but if you are seriously interested, I can bring it to the Ft. Wayne hamfest next weekend. Otherwise, within a reasonable drive of the Chicago NW suburbs. 73 Tony - W9JXN 847-428-4058 Pictures are available. Article: 100586 of rec.radio.amateur.boatanchors From: "M. J.

Black offered absolutely nothing to the thread except frustration. If you can't offer info then don't reply. If you want answers, you need to get on moderated forums. They are just as free as usenet. As a matter of fact, some ISP's don't offer very good usenet access so you have to pay extra to get a good usenet provider. I don't ever ask questions on usenet anymore.
