To prevent noise interference during signal losses due to fading, carriet resupplies oscillator, and amplifier replaces lost carrier, within 0.1 millisec. Q1 and Q2 are switched from cutoff when carrier is needed. Resistor RF in series with crystal lowers its Q to insure rapid starting. -Microwave Relay Designing with Traveling-Wave Tubes, Electronics, 35:3, p 40-43.
