SCR-299

The SCR-299 was a U.S. Signal Corps mobile military communications unit used during World War II.

The SCR-299 "mobile communications unit" was developed to provide long-range communications during World War II. The US Military sought improvements of range, flexibility and durability over its existing SCR-197 and SCR-597 transmitters. In 1942, Hallicrafters Standard HT-4 was selected as the SCR-299's transmitter, known subsequently by its military designation as the BC-610. The SCR-299 was first used on November 8, 1942 during Operation TORCH involving companies of the 829th Signal Service Battalion establishing a radio net that could exchange messages between beach-landed forces and bases in Gibraltar. Despite initial problems unloading the sets from convoy ships, the SCR-299s served until the installation of permanent Army Command and Administrative Network stations. According to US Army military historians, "General Dwight Eisenhower credited the SCR-299 in his successful reorganization of the American forces and final defeat of the Nazis at Kasserine Pass."

The range of the SCR-299 exceeded original specifications, sometime establishing contact over 2,300 miles (3,700 km).

The SCR-299 provided reliable communications with England during the North African campaign, and in Normandy on D-Day, served as a connection between two airborne divisions with Britain. The SCR-299 was also used in the invasion of Sicily and the Allied invasion of Italy.
