In a recent electronics mag (I cant remember which) there was an article on how to build a TV transmitter. The author was selling the project in kit form for around 70-100 bucks. Each price reflecting the low, and high power kits respectively. The high power kit was 2 watts and was "to be used only by technician class" or some such disclaimer. My question is, does anyone know what the name of this magazine was and more importantly, can anyone attest as to the quality or functionality of this kit ? Or maybe even give some sources of kits that are known positively to work? It seems like this could be an interesting project to spend some time with. I'm not really concerned with any kits range as long as it can produce a clear, quality signal. Linear amplifiers are unbelievably simple to come by, in fact probably criminally easy to come by. :-) ------------------------------------------------------------------------ steelie@bucsf.bu.edu ------------------------------------------------------------------------

The magazine was Radio-Electronics and a Technician Class ham license is required. (You can get this license without having to learn Morse Code, thanks to a recent change in the rules; just memorize a few rules about frequency bands, and you probably already know enough theory.) All I remember about the transmitter was that I had the vague impression that it looked good. -- ------------------------------------------------------- Michael A.

I can't tell you about how good it is or things like that. Robert

I purchased the transmitter, and found the project to be very good. It took a while to get it tuned up right - the power output has to be just right to get high quality video. It is a 4" by 3" or so PCB, with parts for about $130. I hacked it into a 1" by 9" device so I could fit it onto a railroad car. Coupled with a Lionel Railscope (1" by 8" camera, in another car) the results are pretty good. There are only two problems. One, it draws two amps, and two, I can't fit the antenna into the railroad car because it interferes with the transmitter. Anyhow, it delivered what was promiced. (There is also a version for UHF channel 14 & 15, which is technically illegal if using the 2W version.) It is available from North Country Radio in upstate NY. Unfortunately I don't have the address here, you'll have to look it up in the magazine.

If you're talking about the PC-Electronics ATV transmitter, I can give you
a quick review. I like it. It works as expected, and has plenty of versa-
tility to meet most needs. The licensing requirements are indeed amateur
technician class or higher, since it uses (large) portions of the 70cm band
(440 MHz). They also have models that operate on 902-928 (along with all of
those cussed Part 15 transmitters) and 1240-1300 MHz.
