Note
The Harris C-11329 (officially designated as the C-11329/URC) is a remote control unit designed to operate military high-frequency (HF) radio systems, most notably the Harris RT-1446 (RF-350).
Manufactured by Harris Corporation (now L3Harris), this unit serves as the command center for the RT-1446/URC receiver-transmitter, allowing operators to control the radio from a distance.
These units saw heavy deployment throughout the late 1980s and 1990s by the U.S. military (including the Air Force and Navy) for secure, long-haul high-frequency communications.
Here is a breakdown of what it does and how it fits into the system:
– Remote Operation: It allows personnel to operate the heavy-duty transceivers and linear amplifiers (often pushing 500 to 1,000 watts) from a safe or more convenient location up to hundreds of feet away. It interfaces via RS-232C, RS-422, or conventional two- and four-wire telephone lines.
– Full Control: The front panel keypad and LCD replicate the controls of the transceiver itself. Operators can punch in frequencies (ranging from 1.6 to 30 MHz in 10 Hz steps), select pre-programmed channels, and adjust audio/RF gain and squelch levels.
– Mode Selection: It supports the selection of various emission modes, including upper/lower SSB, compatible AM, AFSK, and CW.
– Diagnostics: It can initiate the system's Built-In Test (BIT) to automatically isolate faults and troubleshoot the radio equipment remotely.
