ABSTRACT:
There is disclosed a processor controlled scanning radio receiver which employs a microprocessor controller to operate in various modes. One mode of operation is a search/recall mode wherein frequencies located during an automatic search operation are stored in a recirculating storage device for later user recall. The recirculating storage device is also employed to store frequencies or "birdies" to be locked out during a search operation. The channels to be scanned are stored in an electrically alterable read only memory in which the channels are arranged in five banks having ten channels per bank. A keyboard is included via which a user may select or deselect any one or more banks for the scanning operation.
