Overview

GRC-213-0.png
The AN/GRC-213 is an HF low-power transceiver designed for use on wheeled or tracked vehicles. It has the capability of tuning 280,000 different frequencies within the 2– to 29.9999–MHz range. An internal antenna tuner automatically tunes the radio to match any of the three supplied antennas within the operating frequency range. The AN/GRC-213 is made up of Radio Set AN/PRC-104(*), Amplifier-Power Supply AM-7152/GRC-213, interconnecting cables, and Speaker LS-454. The AN/PRC-104(*) can also be used separate from the vehicle as a man pack radio set if desired

Capabilities and Features

The AN/GRC-213 is an HF radio set that provides reliable long-range communication for wheeled or tracked military vehicles. The AN/GRC-213 incorporates the AN/PRC-104(*) man pack radio (less battery pack) with an amplifier–power supply and loudspeaker to produce a vehicular system. The AN/PRC-104(*) can also be used with a battery pack for man pack operation. For the detailed capabilities and features of the AN/PRC-104(*), refer to the equipment description paragraph in TM 11-5820-919-12. The amplifier–power supply conditions and filters the vehicular power source for the radio set, in addition to amplifying and squelching the audio output to drive the external loudspeaker. The AN/GRC-213 is easy to install and remove because of quick-release fasteners and connectors. The AN/GRC-213 controls are easy to operate even if the operator wears gloves. Blackout operation is possible because audible indicators are used rather than lighted meters or indicators. These audible indicators provide warning of low vehicular power, transmitter failure, or antenna tuning fault. The watertight AN/GRC-213 maintains frequency stability over the operational temperature range of -46° to +71°C. Pushbutton frequency selection provides 280,000 channels from 2 to 29.9999 MHz in 100-Hz increments with selectable voice/data/cw modes in both upper or lower sideband operation.

AM-7152/GRC-213 Amplifier Power Supply

The amplifier-power supply, together with interconnecting cables, provides interface and isolation between the AN/PRC-104(*), Speaker LS-454/U, and the Vehicle Inter-communication System AN/VIC-1(V). The amplifier–power supply receives input power from the vehicle power source through an electrical power cable assembly. The amplifier-power supply fully conditions and filters the power to protect the AN/PRC-104(*) from over voltage, noise spike transients, radio-frequency interference (RFI), and reverse polarity. The conditioned and filtered power is sent to the amplifier/coupler through another electrical power cable assembly. An audio amplifier with squelch circuitry is provided in the amplifier-power supply for driving an LS–454/U external loudspeaker with one watt of audio power. The amplifier-power supply can interface with the AN/VIC-1(V) to provide a remote handset operation capability. It can also interface with the AN/VIC-1(V) and a VHF FM radio set in the vehicle to provide retransmission capabilities.

PRC-104 Power Supply Cable

The Power cable that provides filtered power to the PRC-104 is often difficult to source. I already had an "Extension" cable that is used to separate the Battery from the radio, so i decided to cut that cable and use Anderson Power Poles to create a multiple use cable assembly. If required, i can take this cable off and use it in the extender again, or hook this connector to another convenient power source.

Special Note about Anderson Power Pole use in a 12 / 24 Volt Mixed environment
Anderson power poles are quite useful, however they can cause significant confusion and frustration when you are operating equipment in a mixed environment of 12 and 24 volts. Mixing the voltages can be disastrous to equipment, especially when accidentally putting 24 volts on a 12 volt radio. The normal side by side configuration of the 12 Volt connections is very standard, but there is no accepted universal method to handle 24 Volts. Some are trying a 90 degree rotation of one pole for 24 volt, but its far from universally accepted. At any rate I can always remove the pins from the connector and reinsert in whatever configuration i desire later without unsoldering..
