Our Repeater Controllers

We believe that our repeater controllers have the best price/performance ratio in the industry. Besides good value, there are several good technical reasons to choose NHRC:

  • Electrically quiet design
    Our controllers feature a "bus-less" design. This dramatically reduces EMI and the consequent interference problems and noise that can come with conventional microprocessor-based controllers.
  • True Speech
    Speech synthesizers sound so eighties. Many of our repeater controllers offer true speech that sounds much more natural and intelligible than old-fashioned speech synthesizers.
  • Status Display LEDs
    All of our controllers, except the NHRC-2, have status display LEDs that make controller installation and setup a snap.

This is our very smallest controller. It can be used as a conventional repeater controller, an IDer, or a beacon controller. It measures 2" X 1 1/4", allowing it to be installed almost anywhere with mounting tape.

After 15 years, we could no longer get the parts for the NHRC-2 any more. We sold thousands of NHRC-2s, so it was a tough thing for us to try to top it. We think we did with the NHRC-2.1: it's the NHRC-2 with twice the voice storage, plus a real CTCSS input and fan control output. The NHRC-2.1 continues the tradition of the NHRC-2, an inexpensive repeater controller with 4 stored voice messages. Available as a partial kit or assembled and tested.

We've continued to enhance one of our most popular repeater controllers, making it even more powerful and easier to use. The NHRC-3.1 has 8 real speech messages you record, diagnostic status LEDs, a CTCSS input, multi-tone courtesy tones, a fan control output, two digital outputs, two courtesy tone select inputs, NHRC's unique audio test feature, simpler, more user-friendly DTMF programming, and free Windows-based programming software.
The NHRC-3.1 can control a full-duplex, simplex, or link repeater.

Our inexpensive linking repeater controller, as seen in the September 1998 issue of 73 Amateur Radio Today. Available as both a partial kit and assembled and tested.

A linking repeater controller with real stored speech, digital I/O, an auxiliary audio input, etc. A highly integrated design, with state-of-the-art components, results in a powerful, reliable, but still affordable, repeater controller.

The NHRC-7 is a true dual-port bridging repeater controller. It can be used for two duplex repeaters, a duplex repeater with a link radio, or to build a bi-directional cross band repeater with simplex radios. This allows a variety of unique applications, including inter-system radio bridges. Each port can have it's own ID message, or no ID at all, making the NHRC-6 ideal for interoperating with IRLP systems. The NHRC-7 includes a dedicated control receiver port, digital inputs and outputs, and flexible CTCSS encoder control.
