Aug 14, 2019 · RT-671; two man, pack-portable HF USB/CW transceiver. Collins designed and built for use by Special Forces. Ops 2-12mc on any one of 10,000 synthesized frequencies spaced every 1kc. RF output power is 100 watts (high) or 20 watts (low).

Jan 17, 2011 · It seems that the PRC-47 was primarily used by the US Marine Corps in Vietnam but there are many references to its use by the USAF and US Army as well. They were also used by the Navy during Market Time coastal patrol operations as a base operations radio supporting Swift boat comms.

The RT-671/PRC-47 is a two-man team pack transceiver for CW or SSB voice communication in the 2.0-11.999 me frequency range. It features simplified digital tuning in 10,000 channel increments with the operating frequency indicated directly on an illuminated dial.

Oct 11, 2000 · The PRC-47 is an Vietnam ear H.F. radio designed to be carried by two soldiers. One carries the radio and the other carries the battery.

It is a versatile and reliable radio that is particularly weather resistant unlike the FRC-93 (Collins KWM-2) that also saw widespread use in fixed installations. The Australian Army also used the PRC-47 in Vietnam. The transmitter has a PA driver tube and the PA output tube.

The PRC-47 as we all know, is a fine radio. I'll begin with the little bit of historical information I now. As early as 1960 the PRC-47 was in existence, & as far as I know there was never a government contract with Collins to developed the radio.

Any receiver-transmitter unit that is suspected of containing hydrogen fumes should be vented by removing Cover, Panel CW-647/PRC-47 and then removing the receiver-transmitter chassis from its case. Before stowing or shipping a radio set, the used batteries should be exchanged for unused batteries.

The AN/PRC-47 transceiver was developed by Collins in the mid-sixties and was mainly used by Special Forces, for example in the Vietnam War. The transceiver can be operated with 110 V (400 Hz, corresponding to the common aircraft on-board voltage in the sixties) or with 24 DC.

Converter-Blower CV -2455/PRC-47 (figure 1-1, referred to as the CV -2455), provides a single channel, half-duplex teletypewriter communication using the single-sideband circuit of Radio Receiver-Transmitter RT-671/PRC-47 (referred to as the RT-671). The CV -2455 is designed for use with the RT-671 only.

Sep 14, 2009 · The PRC-47 is a Vietnam War era SSB transceiver designed to operate from 2.000 to 11.999 MHz in 1 KHz steps. It is USB only, but can also operate CW or FSK, and it's designed to be powered by either a DC supply (from 24 to 28 VDC) or a 115 VAC, 400 Hz supply.
