1929 transmitter build - Ve3ids Don - 2020-05-21 With the spare time at home, I have been playing on the bench. I built a '29 era transmitter from a 1934 QST. It uses a pair of #245 tubes in a push pull collpits design. It runs on 80 and 40 metres with a maximum of 3 watts output. The coils are wound from some heavy square copper wire that I think was for large transformer winding. Even the board is vintage, it was in the scrap heap in the old barn. It cleaned up in the planer. A very enjoyable project with lots of learning along the way. RE: 1929 transmitter build - Tom VA3TS - 2020-05-21 Great job !

RE: 1929 transmitter build - VA3KOT John - 2020-05-27 Excellent Don. Do you have plenty of spare tubes? Old tubes must be hard to come by.

I don't have a supply of old tubes but Dave ve3ebm has a reasonable collection and has been very generous in supplying tubes and vintage parts for the project. 73 Don ve3ids |
