The SCR-270 was one of the first operational early-warning radars. It was the U.S. Army's primary long-distance radar throughout World War II and was deployed around the world. It is also known as the Pearl Harbor Radar, since it was an SCR-270 set that detected the incoming raid about 45 minutes before the December 7, 1941, attack on Pearl Harbor commenced.
The United States Army Signal Corps (USASC) is a branch of the United States Army that creates and manages communications and information systems for the command and control of combined arms forces. It was established in 1860, the brainchild of Major Albert J. Myer, and had an important role in the American Civil War. Over its history, it had the initial responsibility for portfolios and new technologies that were eventually transferred to other U.S. government entities. Such responsibilities included military intelligence, weather forecasting, and aviation.
Camp Evans Historic District is an area of the Camp Evans Formerly Used Defense Site in Wall Township, New Jersey. The site of the military installation is noted for a 1914 transatlantic radio receiver and various World War II/Cold War laboratories of the United States Army. It was designated a National Historic Landmark District in 2012, in recognition of the site's long role in the development of modern civilian and military electronic communications.
The SCR-268 was the United States Army's first radar system. Introduced in 1940, it was developed to provide accurate aiming information for antiaircraft artillery and was also used for gun laying systems and directing searchlights against aircraft. The radar was widely utilized by both Army and Marine Corps air defense and early warning units during World War II. By the end of World War II the system was already considered out of date, having been replaced by the much smaller and more accurate SCR-584 microwave-based system.
The SCR-536 was a hand-held radio transceiver used by the US Army Signal Corps in World War II. It is popularly referred to as a walkie talkie, although it was originally designated a "handie talkie".
Signal Corps Radios were U.S. Army military communications components that comprised "sets". Under the Army Nomenclature System, the abbreviation SCR initially designated "Set, Complete Radio", but was later misinterpreted as "Signal Corps Radio."
The BC-610 was a radio transmitter based on the Hallicrafters HT-4 and was used by the U.S. Army Signal Corps during World War II.
The SCR-694 was a portable two way radio set used by the U.S. military during World War II.
The BC-342 was a World War II U.S. Army Signal Corps high frequency radio receiver. It was used primarily as part of field installations such as the SCR-188A, but could be used with mobile sets such as the 2 1/2 ton mounted SCR-399. First designed at Fort Monmouth, New Jersey by the U.S. Army Signal Corps, it was built by various manufacturers including RCA. Many of the later units that are encountered today were manufactured by the Farnsworth Television and Radio Corporation of Fort Wayne, Indiana. Variants include the low frequency coverage BC-344 receiver, and the battery or dynamotor powered BC-312 receiver.
The AN/MRN-1 was an instrument approach localizer used by the Army Air Force during and after World War II. It was standardized on 3 July 1942. It replaced the SCR-241, and was a component of SCS-51.
The AN/MRN-3 was a marker beacon set used by the Army Air Force during and after World War II, it was standardized 23 October 1943, and replaced SCR-241.
Signal Corps Laboratories (SCL) was formed on June 30, 1930, as part of the U.S. Army Signal Corps at Fort Monmouth, New Jersey. Through the years, the SCL had a number of changes in name, but remained the operation providing research and development services for the Signal Corps.
The SCR-68 was a military radiotelephone used by the US Army Signal Corps as an aircraft radio in the waning months of World War I. Due to its many problems, primarily its inability to communicate with other radios, like its ground component the SCR-67 or the larger truck mounted SCR-108, over large distances, the SCR-68 quickly became obsolete. Nonetheless, the SCR-68 was one of the first steps towards developing more effective messaging between pilots and commanders, even beyond military usage.
The SCR-108 Radio Truck was a Signal Corps Radio vehicle used by the United States Army during and after World War I for short range air-to-ground communications,
The SCR-189 was a mobile Signal Corps Radio tested by the United States Army before World War II. It was designed for armored forces, and mounted in the Six Ton Tank M1917. The original production run of these tanks included 50 "radio tanks" but the original radio components are unknown, so what or how many tanks were fitted with the SCR-189 also appears to be unknown.
The SCR-245 Radio was a mobile MF/HF Signal Corps Radio used by the U.S. Army before and during World War II, for short range ground communications, It was one of the first crystal controlled sets used by the Army.
The SCR-508 radio was a mobile Signal Corps Radio used by the U.S. Army during World War II, for short range ground communications. The SCR-508 series radio represented the Army's commitment to both FM and crystal tuning, and was used extensively by armor and mechanized units. The turret bustle of late series light and medium tanks was designed around this radio.
The SCR-193 was a series of Signal Corps Radio sets used by the U.S. armed forces in World War II.
The SCR-54 was a tunable, portable crystal radio receiver used by the U. S. Army during World War I for fire control in conjunction with airplanes.
