Repeater Controllers

Our controllers range from the NHRC-2.1 partial kit, an inexpensive repeater controller with real stored speech, to our top-of-the-line NHRC-10 Advanced Repeater Controller. We currently are selling ten different repeater controller products, as well as three repeater accessory products.

Repeater Controllers for GE MASTR II & Custom MVP

We make versions of some of our popular repeater controllers for the GE MASTR II and Custom MVP. The NHRC-3/M2+ and NHRC-4/M2 fit in MASTR II mobiles and stations, and the NHRC-4/MVP is installs inside the Custom MVP. We also make the NHRC-VSQ,a internal plug-in volume and squelch control for the GE MASTR II, and the NHRC-M2/SC MASTR II station interface card.

Repeater Accessories

We manufacture a variety of repeater accessories, including the NHRC-DAD Digital Audio Delay and the NHRC-Squelch, a microprocessor controlled squelch that fights signal fade.

DTMF Remote Control

We also make the NHRC-Remote+, an Intelligent DTMF Remote Control for up to 8 loads, which can provide command confirmation and other feedback.

Partial Kits

We provide several products as partial kits, for experimenters and hobbiests. Our partial kit products include the printed circuit board, difficult-to-obtain components, and complete assembly guides. The NHRC-2.1 is available as a partial kit.

Our Philosophy about Firmware and Software

You won't be seeing lots of firmware updates for our products. Our products are functionally complete and fully tested at the time of shipment. We are not in the Windows software business, either. For our products that can be programmed from a Windows PC, the Windows software is included in the purchase price, and free for our customer and prospective customers to download from our web site. We are a controller company, not a software house.

We have over 2,500 satisfied customers, and there are thousands of repeaters worldwide operating with NHRC products.
