Unwanted sideband down approximatly 40 db. Carrier suppression approximately 50 db. Receiver selectivity also determined by crystal filter. Transmits automatically on receiving frequency. Mechanical, electrical, and thermal stability exeptionally high.
Oscillators are voltage regulated and temperature compensated.
Audio response essentially flat from 300 to 3000 cycles on both receive and transmit. Homebrew, Heathkit, or Collins power supplies can be used with some modifications. When transmitting, audio from a high impedance microphone is amplified in the two triode sections of V11, a 12AU7. Modulation and carrier suppression are taken care of in the 7360 balanced modulator, V9. This gives a rated carrier suppression of about 50db.
