ABSTRACT:
An RF communications system assures selection of the optimum frequency for establishing a communications path between two stations by employing scanning transceivers which may be operated on a plurality of channels having programmed frequencies wherein the programmed frequencies in one transceiver may be automatically changed from another transceiver after establishing a communications path over one of the channels and, when calling another transceiver, the calling transceiver automatically reverts to the same channel last used for communications contact with the called transceiver.
