ABSTRACT:
Eliminating self quieting in a receiver by operating the crystal oscillator in a parallel mode of operation until a harmonic falls within the passband of the receiver and then switching the oscillator to a series mode of operation, which is separated sufficiently from the parallel mode of operation so that no harmonics fall within the passband.
