Abstract
A scanning radio receiver intended for use on the frequencies assigned to the Public Safety Radio Services and which is also operable for reception in the aircraft band from 118 MHz to 136 MHz. A ROM contains data establishing frequency limits and other information such that frequencies assigned to a number of service categories can be automatically searched in response to operation of service keys of a keyboard with the information storage requirements being minimized. For a service band having single frequencies or groups of frequencies which are not separated by fixed frequency increments, the data identifies the number of such frequencies or groups, the number of frequencies in each and a limit frequency of each. A processor outputs a frequency code to a frequency synthesizer while also processing input and stored data to develop the next code to be output.
