ABSTRACT:
A receiver is disclosed for signal-seeking operation on a plurality of channels. The receiver uses power cycling of the RF amplifier stage, mixers, local oscillators and intermediate frequency amplifiers which is in synchrony with the electronic stepping switch used to sequence among the channels. The power which is cycled to these portions of the receiver passes in series through light emitting diode channel indicators.
