Abstract
A scanning FM monitor receiver is disclosed which is of the superheterodyne type and is capable of scanning and receiving a plurality of channels on a plurality of bands. The receiver incorporates a phase-locked-loop frequency synthesizer which eliminates the need for crystals for every channel. The input data that the synthesizer requires to develop the individual preselected frequencies is provided by a random access memory that is programmed by the user for the frequencies desired. Indicator lamps on the receiver illuminate when a channel is being scanned and also provides a visual accuracy check when an operator programs the random access memory with the data codes for producing the various frequencies.
