There are various versions of this receiver, produced by different manufacturers. There are considerable differences between models, including major valve variations and differences in IF frequency. External connections and controls are identical.
The BC-1206A was manufactured by Detrola and used a 6K7 RF, 6SA7 Osc/Mix, 6SK7 IF, 6SQ7 Det/Audio and 28D7 Output. The IF frequency is 142.5 Kc
The radio is very small, with the front panel being 4" square and the radio being 6 5/8" deep. The set mounted directly on the instrument panel in the cockpit of the plane.
The receiver was designed to operate entirely off the 28v aircraft battery supply - hence both LT and HT is 28 vdc.
The set is designed for a very short antenna, with provision being made for high (4000 ohm) or low (300 ohm) impedance headphones. Input sensitivity is 5 micro-volts, with power output of 300 milli-watts.
Overall current drain at 24vdc is quoted at 0.75 A.
