ABSTRACT:
A networked radio communication system for transmitting a radio signal between a source transceiver and a plurality of destination transceivers. The source transceiver first transmits an interrogate signal that includes a synchronize code and an address code that is indicative of a particular destination transceiver. If the particular destination transceiver receives the interrogate signal, an acknowledge signal that includes the address of the destination transceiver that is transmitting the acknowledge signal is transmitted back to the source transceiver. The source transceiver compares the address included in the interrogate signal with the address included in the received acknowledge signal and determines if a communications link is established. If a communication link is established, a feedback signal is provided to the operator of a source transceiver indicating that the source transceiver is in communication with the particular destination transceiver. The feedback signal preferably includes a sidetone signal which allows an operator of the source transceiver to monitor signals transmitted from the source transceiver to the plurality of destination transceivers.
