  • Patent number: 4270213
    Abstract: A channel selector system in a radio for sequentially selecting one of a plurality of channels and rapidly scanning through any restricted channels such that the restricted channels are not displayed and appear to be skipped. The radio includes a frequency synthesizer for generating a predetermined frequency associated with each selected channel and the channel selector system has a signal generator which causes the frequency synthesizer to sequentially either step or scan through the channels including some channels which may be restricted. The generator provides an output coded signal to indicate selection of a restricted channel which is decoded by decoding circuitry. A scan timer is responsive to the decoded signal to cause the signal generator to rapidly scan through restricted channels. A latching circuit latches a signal generator input during rapid scanning through restricted channels until the system advances to the next unrestricted channel. Related methods are disclosed.
