Receiver-transmitter, FM, 30-74.95MHz, 50 KHZ spacing, 920 channels. Manual tuning version of RT-246/VRC with built-in loud-speaker. The RT-524/VRC is the major part of AN/VRC-12 vehicle radio station typically used in M151 Truck, Utility ¼-Ton, 4x4 Mutt Jeeps series of vehicles as well as in older Humvee's and tanks.

Operates from 24 VDC vehicle battery or power supply. Transmitter output power 8W (low) and 35W (high).

Noise-operated squelch as well as an advanced tone-operated squelch (150 Hz) is provided. The tone squelch provides reliable retransmission when two receiver-transmitter are used as an automatic relay station.

The AN/VRC-12 is a combat-proven vehicular radio set that lends its self particularly well to applications of tactical deployment and specific operational missions because of their ability to be assembled into various configurations and of being installed on most types of military vehicles such as M-151 Mutt Jeeps, Humvees, heavy armour, etc.
