- Notes
- Collins 75A-1 Amateur Band Communications Receiver: Double conversion, AM/CW, six amateur bands from 80 - 10 meters (3,2-4,2 / 6,8-7,8 / 14-15 / 20,8-21,8 / 26-28 and 28-30 MHz), five step crystal filter 0.2 to 4 kHz, optional mechanical IF filters.
Sometimes referred to as 75A:
Osterman states: "One view is that the 75A-1 was simply referred to as Collins 75A until the 75A-2 came out in 1950. Another theory suggests that a small run of < 200 75A's were made in 1946." Moore has in his remarks: "Early 75A" and shows an image without limiter switch, in the remarks of the 75A-1 he states "Differs from 75A in limiter switch on right side above function knob"
Further clarification about this matter is still needed.
