TUNWALL TRC-1 SINGLE SWITCH CONTROLLER, FOR 2 TRANSMITTERS, ONE ANTENNA AND A DUMMY LOAD. FOR FM, NON-DIRECTIONAL AM OR TV INSTALLATIONS
The pre-programmed PLC (programmable logic controller) in the TRC-1 provides control and logic for the coaxial switch and transmitters. The coaxial switch plugs into a 9-pin AMP connector on the controller, and transmitter and remote control connections are made to barrier strip terminals.
The TRC-1 has automatic plate on for transmitter 2 when auto transfer is enabled. This is enough automatic control for many stations. For additional plate control, see the TRC-1P. The TRC-1 is compatible with all standard coaxial switches, and can also be used with RF contactors for non-directional AM stations.
