ABSTRACT:
An audio squelch control for transceiver stations in which all transceivers are initially in a Call mode with the squelch control turned on. While in the Call mode, the squelch control is turned off, enabling the speaker, by receiving the station's coded address, plus a flag bit that is set, from a transmitting station. In addition to having the squelch circuit turned off, the receiving station is changed from the Call mode to an Auto mode. When in the Auto mode, the squelch control is turned off by receiving the station's coded address with the flag bit turned off. The squelch control of a station in one mode does not respond to a station in the opposite mode even if it receives its own coded address.
