6 Meter Converter from 1950s 1960s - Ham Radio Downconverter
1950-s1960 6 meter to 40 meter downconverter I believe from a December 1960 QST - A single oscillator at 43.000 MHz with the fundamental output fed into a mixer would take the 50 MHz signal down to 7 MHz.
- 43 MHz crystal (43.0000 MC)
- 12 AT7 Tube (Combined Oscillator/Mixer/Amp)
- 6AK5 Tube RF/IF Amplifier
- Includes power Supply Section
