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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SCR-68
The SCR-68 ( SCR was a military term meaning Set, Complete, Radio) was a military radiotelephone used by the US Army Signal Corps as an aircraft radio in the waning months of World War I.Stoller, H. M Engineering Dept, Western Electric Company, Inc. “Development of Airplane Radiotelepone Set.” The Electric Journal May, 1919. 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. Capabilities The SCR-68 had a few distinct characteristics that separated the SCR-68 from other types of radio. The SCR-68 operated at 750 kHz (400 meter wavelength), using a long wire antenna reeled out behind the aircraft. It could receive and transmit messages over a maximum range of ei ...

Radio Tractor
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.

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Motor Company
The White Motor Company was an American automobile, truck, bus and agricultural tractor manufacturer from 1900 until 1980. The company also produced bicycles, roller skates, automatic lathes, and sewing machines. Before World War II, the company was based in Cleveland, Ohio. White Diesel Engine Division in Springfield, Ohio, manufactured diesel engine generators, which powered U.S. military equipment and infrastructure, namely Army Nike and Air Force Bomarc launch complexes, and other guided missile installations and proving grounds, sections of SAGE and DEW Line stations, radars, Combat Direction Centers and other ground facilities of the U.S. aerospace defense ring, such as the Texas Towers. During the Vietnam Era, the company retained its position within the Top 100 Defense Contractors list (it ranked 87th in the Fiscal Year 1965, 77th in 1967, 73rd in 1968, 89th in 1969).

Signal Corps SCR-54A Crystal Radio
In signal processing, a signal is a function that conveys information about a phenomenon. Any quantity that can vary over space or time can be used as a signal to share messages between observers. The '' IEEE Transactions on Signal Processing'' includes audio, video, speech, image, sonar, and radar as examples of signal. A signal may also be defined as observable change in a quantity over space or time (a time series), even if it does not carry information. In nature, signals can be actions done by an organism to alert other organisms, ranging from the release of plant chemicals to warn nearby plants of a predator, to sounds or motions made by animals to alert other animals of food. Signaling occurs in all organisms even at cellular levels, with cell signaling. Signaling theory, in evolutionary biology, proposes that a substantial driver for evolution is the ability of animals to communicate with each other by developing ways of signaling. In human engineering, signa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SCR-54
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. History French radio equipment was more advanced than that of the U. S. Army when the United States entered World War I. The U. S. Army therefore adopted French sets early on, and developed improved sets of their own, some based on French design. Several of the French A-1 artillery receiving set were sent to the American radio laboratory in the summer of 1917 and copied with minor modifications. It was first released as the AR-4 in limited numbers for field tests, supervised by Captain Edwin Armstrong. Several changes were made based on his suggestions. The receiver was redesigned and reissued as the SCR-54 (Set, Complete, Radio). Since there was high demand, several companies produced these sets or components, including DeForest Radio Telephone and Telegraph, Liberty Electric, Wireless Specialty Apparatus, Marconi, and General Radi ...

Crystal Radio
A crystal radio receiver, also called a crystal set, is a simple radio receiver, popular in the early days of radio. It uses only the power of the received radio signal to produce sound, needing no external power. It is named for its most important component, a crystal detector, originally made from a piece of crystalline mineral such as galena. This component is now called a diode. Crystal radios are the simplest type of radio receiver and can be made with a few inexpensive parts, such as a wire for an antenna, a coil of wire, a capacitor, a crystal detector, and earphones (because a crystal set has insufficient power for a loudspeaker). However they are passive receivers, while other radios use an amplifier powered by current from a battery or wall outlet to make the radio signal louder. Thus, crystal sets produce rather weak sound and must be listened to with sensitive earphones, and can receive stations only within a limited range of the transmitter. The rectifying prop ...
