AN~TRC-75

radio transceiver

components:
R-761/ARC-58 transceiver
T-730/TRC-75 linear power amplifier
C3141/TRC-75 control box
C-2848/TRC-75 antenna coupler control
CU-749/TRC-75 antenna coupler
AM-2360/TRC-75 microphone and audio aplifier
CV-786/TRC-75 RTTY modem
RF-111/TRC-75

All the above components are inclosed in the case CY 2600/TRC-75.
The power for the TRC-75 is from the inverter PP-2352/UR.
wich convert the vehicular 28 Vdc to a three phases 115 Vac 400Hz ,
one phase is filtered for use with the receiver R-761/ARC-58 and for the various servo amplifiers used in the apparatus.
