Abstract
A circuit that determines which channels of a radio receiver are to be scanned and which channels are to be skipped is programmed or preset by a first switch which selectively energizes an automatic search circuit or a manual channel selector switch and a scan-skip switch. When the channel selector switch is energized, individual channels can be selected. As each channel is selected, a readout circuit provides an indication if the channel has been previously programmed to be scanned, but provides no indication if the channel has been previously programmed to be skipped. Also, each channel selected by the channel selector switch can be programmed for scanning or skipping by the scan-skip switch. The circuit permits a large number of channels to be programmed by only three switches, thus saving space which is limited in very small radio receivers.
