The AN/PRC-127 (or RT-1594) was used in the
military for non-tactical use, such as Military Police
and special events. Made by Bendix King, this
radio was originally made for commercial use.
However it's broad FM range has made it usable
for Military, Civil Air Patrol, Ham Radio Operators,
Marine Band, and Business Band operators.
Frequency Range: 136MHz -- 160MHz (FM)
Standard Sub-Audio Tone Support
Power Out: 3 Watts
Receiver Sensitivity: .25uV

The PRC-127 provides for operator selection of up to 14 independent preset channels in the 136 to 160MHz band. A
microprocessor and a nonvolatile programmable memory are used to provide the independent preset channels
capability. The radio set is also equipped with CODE GUARD circuitry that one radio or a group of radios to be
selectively called within a system. CODE GUARD is a feature used in commercial versions of the radio set. The CODE
GUARD function is present in the R/T produced for the Army.

When the radio set is turned on the unit is in the receive mode. Radio frequency (RF) signals entering the antenna are
converted from RF to an Intermediate Frequency (IF) amplified and demodulated to Audio Frequency (AF). The AF
output is filtered and amplifies and routed to either the internal or external speaker/microphone.
The radio set is placed in the transmit mode when the push-to-talk control on the R/T is pressed. The internal or
external speaker/microphone is used to apply a voice signal to the transmitter. The AF signal is amplified and used to
frequency modulate an RF signal. The modulated RF signal is then further amplified to provide an RF output (signal 2
watts nominal) to the antenna for radiation.
The transmitter is equipped with a timeout timer to limit the duration of calls and to guard against locking in the transmit
mode and tying up the radio net. Them timeout timer inhibits the transmitter after the selected time has elapsed.
Timeout time is selected (0 to 225 seconds) using the keyboard. Setting the timeout time to 0 second disables the timer
fo that the user may talk as long as he wishes.
The 10Vdc (9.6v) is provided by the battery pack.
