The following documents are lists of parts and pieces of equipment apparently intended for Unimog radio box usage. This list was found in the radio box owned by Bob Ragain. (Regretably, only the list was left in the box.) These first 7 pages are from the listing for GRC-7 equipment.
An excellent source of pictures for GRC-7 and other radio equipment is at:
This list has English subtitles of the US/NATO designation for the equipment. GRC-7 equipment is comprised of a series of transceivers and receivers, power supplies, and amplifiers for use in the VHF band (30 to 300 MHz). The frequency range of the GRC-7 is about 25 MHz to 70 MHz and was intended for line of sight, channelized, communications. Several individual transceivers and receivers each cover part of this frequency range.
