  • Patent number: 5887265
    Abstract: A radio (1) for radio communication supportable with repeaters. The radio (1) has a transceiver (2) for receiving information on either a repeater channel or a talkaround channel. A monitor (3) is coupled to the transceiver (2) to provide output signals indicative of channel strengths of the two channels. The output signals are compared by a controller (4) to provide a selected channel from the two channels. Information is then received by radio (1) on the selected channel. When receiving the information, the controller (4) periodically controls the transceiver (2) to receive on an unselected channel of the two channels. The monitor (3) then provides a new output signal corresponding to the unselected channel for the controller (4) to re-compare and re-select the selected channel.
