Ten-Tec Universal BFO Kit

Got an old (or very new) AM only shortwave radio with no CW-SSB capability? If you want to enjoy casual CW-SSB reception, this varactor-tuned 455 kHz oscillator may be built into larger receivers or else mounted in its own case and placed near your portable SWL radio. The on board tuning control compensates for alignment variations from one receiver to another in addition to permitting fine-tuning of SSB/CW signals. Operates on 6 to 15 VDC. link
