NHRC-6 Bridging Repeater Controller

The NHRC-6 is an advanced, low cost bridging repeater controller. It has a highly integrated design, using state-of-the-art components, which results in a powerful controller with a low parts count. This increases reliability and lowers cost.

This controller can be used to control two duplex repeaters, a duplex repeater with a link radio, or to build a bi-directional cross band repeater with simplex radios.

The NHRC-6 has two radio ports. Each radio port supports a receiver and a transmitter. Each receiver is individually configurable. Receiver configuration includes such parameters as receiver enable (on/off), access mode (CAS, CAS and CTCSS, CAS or CTCSS, and DTMF,) timeout timer enable, and DTMF muting. Each receiver can specify which transmitter(s) will be used to repeat the receiver's audio.

Each transmitter is also individually configurable. Transmitter controls include transmitter enable (on/off), hang time enable, courtesy tone enable, ID enable and selection of one of two CW ID messages.

The architecture of the NHRC-6 allows the controller to be used in a variety of different applications. These applications include simultaneous control of two repeaters, each with it's own ID message, control of a repeater with a link radio, including linking modes compatible with IRLP and full-duplex link environments, as well as the controller forming a "bridge" in conjunction with two simplex radios, allowing simple and reliable linking of completely separate radio systems.
