ABSTRACT:
A rapid channel skip system for radio receiver having a single channel skipping switch to inhibit the radio receiver from receiving any of selected channels of a plurality of channels of predetermined frequencies while scanning repetitively those channel selected to be received. A clock oscillator having a scan frequency controls the scanning time of channels to be received and a skip oscillator having a skip frequency oscillates for one cycle to skip over a channel. The channel skipping switch is utilized to skip, inhibit, bypass, look around, etc., any channel of a plurality of channels a listener does not wish to receive when the rapid channel skip system connected between the squelch control and the oscillator of the radio receiver has stopped on a channel while scanning in the scan mode or has been stepped to a particular channel by the channel stepping switch in the manual mode by actuating the switch. If the channel skipping switch is actuated a second time when utilizing resettable memory elements on an inhibited channel in the manual mode, the channel is enabled. The channel stepping switch is not usable in the scanning mode. A received channel may be skipped in the scanning mode on the next scanning cycle by actuating the channel skipping switch while that channel is receiving a signal. In the manual mode of operation, each channel is skipped by actuating the channel skipping switch setting a memory for each channel to be skipped. When going from the manual mode to scan mode, the memory having been set determines those channels to be received and those channels to be skipped. A reset switch resets all channel memories which are set or inhibited.
