This page contains links to scanned images of a 1967 installation manual which describes the “correct” way to install radio sets AN/VRC-46, AN/VRC-53, or AN/GRC-125 in the M37 truck. Each page was scanned at 150 DPI and saved as a GIF image. This is the complete manual; the original was unbound, and consisted of two double-sided sheets followed by five foldouts, 3-hole punched and stapled together without any cover.
The AN/VRC-46 radio set is a member of the AN/VRC-12 series. It consists of an RT-524 transceiver, MT-1029 mount, and antenna AT-912/VRC or AT-1729/VRC.
The AN/VRC-53 radio set is a vehicular installation of the AN/PRC-25 backpack radio set. It consists of transceiver RT-505/PRC-25, amplifier/power supply OA-3633, mount MT-1029, and antenna AT-912/VRC. Radio set AN/GRC-125 is the same as the AN/VRC-53 set, except that it also includes additional components that allow the user to remove the RT-505/PRC-25 and use it as a backpack radio.
