Abstract
A method and system for scanning channels in a network for incoming audio transmissions. A device enters an intelligent scanning mode, which initiates an automatic scanning of predefined channels for incoming audio transmissions. Upon detection, the device tunes to the channel of the incoming audio transmission while continually searching channels of a higher priority for incoming audio transmissions of a higher priority. A device enters a single channel mode to send an outgoing transmission, which automatically reverts the device to the channel of the last incoming audio transmission.
