Sideband Engineers Model 34 SSB Transceiver
80/40/20/15 Mtrs, 12VDC/110 AC, SSB Transciever Transistor & Tube Radio
WB6FZH- Yes, even though there are some transistors and diodes in this radio, it is a true classic. It utilized state-of-the-art technology for it's time, and sported a 2.1 kc Collins Mechanical Filter used both in the detection and generation of the SSB signal.
This unit is shown with the SBE "Codapter" and an after-market PTT microphone(LO-Z). The Codapter, generated a close to sine-wave audio tone that was introduced into the microphone jack, generating an aparently legal type of "CW". Very few adapters were sold, or have survived. The SBE 34 also had a 100 kc crystal calibrator and VOX unit sold as accessories.
