ABSTRACT:
A frequency control circuit for a single sideband receiver is disclosed wherein the local oscillator is swept at a first rate to enable the acquisition of a transmitted signal. When the signal is acquired, the local oscillator is swept at a second rate in an indicated direction in order to center the signal. Upon centering, the local oscillator is maintained at a frequency which centers the signal in response to the activation of a squelch detector.
