The RTS RadioCom models BTR-300 and TR-300 are specifically designed to provide the user with a highly flexible wireless 2-way communication system with the capability to interface with a wired intercom system and other auxiliary audio. At the BTR-300 operator's command, the remote stations can communicate with each other, with a wired intercom system or with an auxiliary system. The BTR-300 base station, with its one (1) transmit and four (4) receive channels is designed to operate in full-duplex (simultaneous 2-way communications) with up to four (4) TR-300 beltpack transceivers. The system operates on selected frequencies within the 174-216MHz band. The BTR-300 system is fully compatible with a number of other wired intercom manufacturers. As many as four (4) TR-300 beltpack transceivers can operate in a full-duplex network with one (1) RTS RadioCom model BTR-300 base station.
