PRC-68 is a "Squad Radio", a small hand held unit for very local communications. The collection shows all American Squad radios from their beginning (1941) to 1986.
A replacement for PRC-6 was needed. Most of the experimental radios were either too heavy, lacked performance or were too expensive.
The last attempt of the Army were two separate radios:
Two-channel transmitter AN/PRT-4 and one-channel receiver AN/PRR-9.
In the mean time, the Marine Corps no longer wanted to wait for response of the Army to have a joint development of a multi- channel transceiver. They combined PRR-9 and PRT-4 in a single case and called it
In the same time frame the Marine Corps started the development of a totally new type of Squad Radio. The development lasted from 1964 to 1976.
In the competition for the PRC-68, prototypes were supplied from Magnavox/Ft. Wayne (now Raytheon) and from Motorola. Magnavox won.

Then RT-1113/PRC-68 was built by Magnavox / Indiana.
