The RF-350K Transceiver is an all solid state, synthesized, single sideband (SSB) transceiver. Operating in the high frequency (HF) band (1.6 to 30 MHz), the Transceiver is tunable in 10Hz steps. The RF-350K Transceiver is an assembly consisting of one RF-350K Transceiver connected to one RF-366 Power Supply. Power for the RF-350Transceiver can be from 115/230 Vac or 12/28 Vdc sources.

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.

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.
