40 db below rated PEP output. Primary fusing in power supply. Image rejection greater than 100 db on 6 meters. Greater than 60 db on 2 meters. The associated h-f transmitter and receiver must cover the range of 14.0 to 14.2 mc.
Plate voltage is removed from the mixer and the first voltage amplifier while receiving.
Injection voltage for both the transmitter mixer and the receiver mixer is supplied by an oscillator-amplifier system, V6, V9, and V10. The crystal oscillator, V6, uses 23 crystals spaced 200 kc apart to provide a total range of 4.6 mc on either 6 or 2 meters. The net inductance of L1 in series with L2 is parallel tuned to the 6-meter band by the combination of C1, C2, and circuit capacitance. Tuning within the band is done by varying the inductance of L2 which consists of a circular ring with a rotating wiper arm. When operating on 2 meters, C2 is switched out of the circuit, L3 is switched in parallel with L1, and L4 is switched in parallel with L2.
