NHRC-3+ Repeater Controller
An Inexpensive Repeater Controller
with Real Stored Speech
The NHRC-3+ is a new, enhanced version of NHRC's popular NHRC-3 Repeater Controller. The NHRC-3+ offers many improvements over the NHRC-3, including simplified programming, a CTCSS input, multi-tone courtesy tones, a fan control output, four digital outputs and two courtesy tone select inputs.

The NHRC-3+ continues the tradition set by the NHRC-2 and NHRC-3. It has a tremendous amount of functionality packed in a design with a very low parts count, resulting in exceptional reliability at an affordable price.

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.
