SBE- 34 SSB TRANCEIVER

Sideband Engineers Model 34 SSB Transceiver

80/40/20/15 Mtrs, 12VDC/110 AC, SSB Transciever Transistor & Tube Radio

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.
. The SBE 34 also had a 100 kc crystal calibrator and VOX unit sold as accessories.
