The transmitter was based on the Tuna Tin Xmtr that appeared in QST many years ago as a CW rig. I added the modulator to make it a phone rig.. It has a 6AH6 crystal oscilator that feeds a 5763 in the final. The modulator is a 12AX7 that drives a 6AQ5. I didn't have a modulation transformer so I used two output transformers back-to-back that worked out well. It is basically designed for 75 mtrs, but I can double in the final and work 40 mtrs, which I have done successfully.
I have been pleased with the way it works, and the reports. I have fed the 811A amplifier, and it drives it very well.
