This page shows the major components of many of the US military vehicular radio sets in use during the 1950's. Each link points to a picture which shows the major radio components, mounts, cables, antenna components, etc. that were used in the indicated radio set. These pictures were scanned from a large foldout in the back of TM 11-284: Radio Sets AN/GRC-3, -4, -5, -6, -7, and -8, dated May, 1953.
When these radios were introduced, different frequency bands were allocated for armored, artillery and infantry units. The bands overlapped each other by 900 kHz, allowing communications between different types of units.
