Abstract
A radio communications system having an automatic tuning frequency scanning operation is provided with a circuit for automatically stopping the frequency scanning operation dependent upon the comparison between the group number information in an output signal from the receiver and a group number which is previously selected by an operator of the system. In order to stop the automatic scanning operation, a signal is produced for controlling the operation of a gate circuit along with a scan signal latch circuit in the frequency synthesizing portion of the system.
