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.

Excellent Don. Do you have plenty of spare tubes? Old tubes must be hard to come by.

Thanks for the kind comments guys. 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.
