Abstract
There is disclosed a scanning radio receiver for use on the frequencies assigned to the Public Safety Radio Services in which frequency modulation is used and which also will receive the aircraft band from 118 to 136 MHz in which amplitude modulation is used. The receiver tuning is varied in response to the operation of a microprocessor controller which provides a control signal indicative of the form of modulation included on signals at the frequency to which the receiver is tuned at any instant. The receiver also includes a search capability and is responsive to user actuated keyboard controls for searching only those frequencies designated for use by a particular service.
