A Precision-Tuned Receiver Employing Solid-State Tuning Elements

The capability of rapid frequency selection coupled with crystal controlled tuning accuracy are the salient features of this solid-state receiver. The heart of the system is a discrete local oscillator. It consists of an electronically tuned oscillator which is phase-locked to a selected harmonic of a master crystal. Since there are no mechanical adjustments necessary, the receiver can be built in a small, light-weight package.
