AN/URC-119

Overview

The RT-1446/URC is a microprocessor-controlled transceiver, conservatively rated at 100 watts PEP and Average output power. The solid-state power amplifier assures continuous full-output power during keydown operation. All operating and metering functions of the transceiver are fully remote controllable over two or four wire phone lines. Additionally, the built-in phone patch and internally mounted AFK option provide communication flexibility. The unit is compatible with standard DD encryption devices, including ANDVT. The exceptionally rugged design and construction of this system guarantee continuous high performance and reliability under demanding field conditions. Automatic diagnostic BITE provides board level fault isolation for the entire system. The AN/URC-119(V) Radio Set is tuned by simply selecting a frequency (or preset channel) and keying. All other functions, including linear power amplifier and antenna tuning, are performed automatically.

NOTE

The RF-350 is rated for continuous duty at 1OOW PEP. the RF-366, "key-down" transmit time should be limited When using an RF-350 in the CW or AFSK mode without to less than 20 minutes, followed by an equal receive period, to prevent automatic reduction of output power RF-350 with an attached RF-366 (as in an RF-350K) the in response to elevated temperature. When using an cooling fan provided in the RF-366 allows continuous CW or AFSK "Key-Down" Operation.
