Assemble Radio Set AN/PRC-119.
Situation: In a tactical environment, you are required to provide FM radio communications from
2d Plt, A Co, 54th In Bn, to the company command post. Due to the rugged terrain in the area where the
platoon will conduct its operations vehicular radios cannot be used. You will use Radio Set AN/PRC-
119 to provide the required single channel communications. All radio transmissions must be secure.
Let's begin our lesson by taking a look at the AN/PRC-119 components, controls and connectors.
Receiver/Transmitter RT-1439/VRC. The RT common to all SINCGARS configurations
used to send and receive messages and net operation information.
(1) Controls and connectors are limited to those on the RT in the manpack configuration.
(a) FUNCTION switch - FCTN - used to select the function you want the RT to perform.
o OFF - turns the RT power OFF but maintains memory. Used to shut down for short
periods of time when memory retention is desirable.
o TST - position causes the RT to perform self test of its circuitry.
o SQ ON/OFF - SQUELCH ON/OFF - ON eliminates unwanted noise in the handset
when there is no signal being received. OFF position allows receiver noise to be heard.
o RXMT - RETRANSMIT, used to relay signals when stations are to far apart or
terrain features prohibit direct communications.
o REM - REMOTE, used to allow for control of the RT from a remote location.
o LD - LOAD, used to enter fill data into the RT from a fill device.
