Abstract
A reception sensitivity control system in a sweeping receiver in which a frequency dividing ratio of a phase lock loop is instantly changed from one end of the band to the other. The number of receivable stations is counted in the period of time required for the phase lock loop to adjust. If the number of stations is less than a preset minimum, the input sensitivity is increased. Thereafter, the channels are selected.
