NHRC-4/MVP Repeater Controller
An Integrated Linking Repeater Controller
for General Electric Custom MVP Radios

The NHRC-4/MVP is a specialized version of our NHRC-4 linking repeater controller, designed for installation inside a General Electric Custom MVP transceiver. The controller installs in place of of the GE channel-guard board.

The controller has a "primary" and a "secondary" radio port. The primary port is used for the controlling repeater, and the secondary port can be used for a remote base, link radio, or "slaved" repeater. Unique courtesy tones provide feedback of the input source and link state.

The controller is programmable by sending DTMF sequences. The CW ID, hang time, ID timer, timeout timer and tail message counter can all be programmed by the user. All programming is password-protected, and is stored in non-volatile EEPROM memory.
