Signal Corps Radio
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." Nomenclature The term SCR was part of a nomenclature system developed for the U.S. Signal Corps, used at least as far back as World War I. Three-letter designators beginning with "SC" were used to denote complete systems, while one and two-letter designators (such as "BC", for basic component, "FT" for mounting, etc.) were used for components. Only a few system designators were used: :::SCM Set, Complete, Meteorological :::SCR Set, Complete, Radio :::SCS Set, Complete, System SCR radio sets The U.S. Signal Corps used the term "sets" to denote specific groupings of individual components such as transmitters, receivers, power supplies, handsets, cases, and antennas. SCR radio sets ranged from the relatively small SCR-536 "handie ta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SCR-105
The Stellarator of Costa Rica 1 (or SCR-1) is a small modular stellarator for the magnetic confinement of plasma located at Cartago, Costa Rica. It is developed by the plasmaTEC group of the Plasma Laboratory for Fusion Energy and Applications at Costa Rica Institute of Technology.

SCR-50
The Radio tractor was a mobile Signal Corps Radio used by the U.S. Army for ground communications before and during World War I. Prior to World War I, trucks were referred to as "tractors", and there were also telegraph tractors, and telephone tractors. Use Very little information exists for these trucks, as most of the components were built before standardization. They first made their debut on the Mexican border in a radio intercept role, and later during World War I, some sets may have been reconfigured for RDF and other uses. Components * SCR-50, 2 kilowatt spark transmitter, crystal or vacuum tube detector receiver, 0.15-0.50 Megahertz Variants At least 3 variants are known: * Radio Tractor No. 1 * Radio Tractor No. 2 (Four Wheel Drive)(Jeffery Quad), Unknown radio set * Radio Tractor No. 3 (White Motor Company), SCR-50 radio set The No.3 truck was also accompanied by a tender "Maintenance truck No. 5" later renumbered as K-5.

SCR-694
The SCR-694 was a portable two way radio set used by the U.S. military during World War II. History The SCR-694 replaced the SCR-284 and was later replaced by the AN/GRC-9. Designed to provide communication between moving or stationary vehicles or as a portable field radio set, the SCR-694 was originally intended for use by mountain troops and airborne forces but soon became the Army-wide standard at battalion level. The SCR-694 saw use all over the army in many different theaters; notable instances include at regimental division headquarters during the Normandy invasion and the Cabanatuan prison raid as well as by scouts and reconnaissance units in the Pacific War. Specifications The SCR-694 "Radio set, Portable/Vehicular" consisted of the BC-1306 vacuum tube transmitter/receiver capable of AM and CW mode operation between 3.800 and 6.500 MHz. *Weight — 19.5 pounds. *Range — up to 15 miles on AM voice. Up to 30 miles reported on Morse code between moving ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SCR-300
The SCR-300 was a portable radio transceiver used by US Signal Corps in World War II. This backpack-mounted unit was the first radio to be nicknamed a "walkie talkie". History In 1940, Motorola (then the Galvin Manufacturing Company) received a contract from the War Department to develop a portable, battery powered voice radio receiver/transmitter for field use by infantry units. The project engineering team consisted of Daniel E. Noble, who conceived of the design using frequency modulation, Henryk Magnuski who was the principal RF engineer, Marion Bond, Lloyd Morris, and Bill Vogel. The SCR-300 operated in the 40.0 to 48.0 MHz frequency range, and was channelized. Along with other mobile FM tank and artillery radios such as the SCR-508 (20.0 to 27.9 MHz) and the SCR-608 (27.0 to 38.9 MHz), the SCR-300 marked the beginning of the transition of combat-net radio from low-HF AM/CW to low-VHF FM.

SCR-284
The SCR-284 was a World War II era combination transmitter and receiver used in vehicles or fixed ground stations. History The Crosley Corporation of Cincinnati, Ohio manufactured the Signal Corps Radio set SCR-284 that consisted of the BC-654 and associated support equipment. The SCR-284 was introduced in Africa during Operation Torch and was the first radio set used for communications from the beach to the U.S. Fleet to coordinate naval gunfire and beach radio networks.The American GI in Europe in World War II: The March to D-Day'. Stackpole Books; 22 September 2009. . p. 51–. The set was used by Merrill's Marauders while operating in the China-Burma-India Theater and missions behind Japanese lines in Burma to communicate with air transport and other military aircraft, although some radiomen complained that it was "very inefficient" compared to other radio sets and "very hard to generate power".Gavin Mortimer.
