Ault Public Emergency Radio Tower
The Public Emergency Radio of the United States was a communications system planned during the cold war era in the 1970s, to be activated in anticipation of a nuclear attack. The radio system was designed to broadcast on 167, 179 and 191 kHz in the long wave radio band. The distribution stations would be activated by two "control stations" at 61.15 kHz, in Ault, Colorado and Cambridge, Kansas. The system was not implemented.

Cold War
The Cold War is a term commonly used to refer to a period of Geopolitics, geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc. The term ''Cold war (term), cold war'' is used because there was no large-scale fighting directly between the two superpowers, but they each supported major regional conflicts known as proxy wars. The conflict was based around the ideological and geopolitical struggle for global influence by these two superpowers, following their temporary Allies of World War II, alliance and victory against Nazi Germany and Empire of Japan, Imperial Japan in 1945. Aside from the Nuclear arms race, nuclear arsenal development and conventional military deployment, the struggle for dominance was expressed via indirect means such as psychological warfare, propaganda campaigns, Cold War espionage, espionage, far-reaching Economic sanctions, embargoes, rivalry at sports events, and technolog ...

Long Wave
In radio, longwave, long wave or long-wave, and commonly abbreviated LW, refers to parts of the radio spectrum with wavelengths longer than what was originally called the medium-wave broadcasting band. The term is historic, dating from the early 20th century, when the radio spectrum was considered to consist of longwave (LW), medium-wave (MW), and short-wave (SW) radio bands. Most modern radio systems and devices use wavelengths which would then have been considered 'ultra-short'. In contemporary usage, the term ''longwave'' is not defined precisely, and its intended meaning varies. It may be used for radio wavelengths longer than 1,000 m i.e. frequencies up to 300 kilohertz (kHz), including the International Telecommunication Union's (ITU's) low frequency (LF, 30–300 kHz) and very low frequency (VLF, 3–30 kHz) bands. Sometimes the upper limit is taken to be higher than 300 kHz, but not above the start of the medium wave broadcast band at 520& ...

Radio Band
The radio spectrum is the part of the electromagnetic spectrum with frequencies from 0 Hz to 3,000 GHz (3 THz). Electromagnetic waves in this frequency range, called radio waves, are widely used in modern technology, particularly in telecommunication. To prevent interference between different users, the generation and transmission of radio waves is strictly regulated by national laws, coordinated by an international body, the International Telecommunication Union (ITU). Different parts of the radio spectrum are allocated by the ITU for different radio transmission technologies and applications; some 40 radiocommunication services are defined in the ITU's Radio Regulations (RR). In some cases, parts of the radio spectrum are sold or licensed to operators of private radio transmission services (for example, cellular telephone operators or broadcast television stations). Ranges of allocated frequencies are often referred to by their provisioned use (for example, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ault, Colorado
Ault is a statutory town located in Weld County, Colorado, United States. The town population was 1,887 at the 2020 United States Census, a +24.23% increase since the 2010 United States Census. Ault is a part of the Greeley, CO Metropolitan Statistical Area and the Front Range Urban Corridor. History First called High Land, the town's name was changed to Burgdorff Siding, sometimes called Bergdorf Switch (after a railroad worker, who was deceased in an accident), before it acquired its current name in 1897. The town was named after Alexander Ault, a Fort Collins, Colorado resident and owner of a flour mill. Mr. Ault had helped to avert financial disaster to the agricultural base by purchasing the entire grain harvest during a year of severe economic hardship. The town was incorporated in 1904. Much of the residential area of the town, as well as surrounding farmland, is on land given by the United States government to the Union Pacific Railroad, to be sold to finance railr ...

Cambridge, Kansas
Cambridge is a city in Cowley County, Kansas, United States. As of the 2020 census, the population of the city was 92. History Like many communities in Kansas, Cambridge owes its existence to a railroad. When the Kansas City, Lawrence & Southern Railroad was built a mile south of Lazette, a new site was organized by Benjamin H. Clover and plotted on May 3, 1880 and it was named Cambridge after Cambridge University, in England. The first post office in Cambridge was established on January 30, 1880. On December 15, 1880 the Atchison Topeka & Santa Fe Railway acquired nearly all the stock of the Kansas City, Lawrence & Southern Railroad and operated the railroad awhile as the Southern Kansas Railroad. Cambridge was a station and shipping point on the Atchison, Topeka and Santa Fe Railway. Cambridge Public Emergency Radio Tower is one of two former emergency transmission facilities built during the Cold War. Geography Cambridge is located at (37.317323, -96.667085). Acco ...

WGU-20
WGU-20 was an emergency government civil defense preparedness radio station in Chase, Maryland USA, operated by the United States Defense Civil Preparedness Agency in the 1970s. Public emergency radio Operating 24 hours a day on a longwave frequency of 179 kHz from Chase, Maryland, WGU-20's programming consisted of pre-recorded announcements (including weather reports) and time checks. The transmitter was situated at 39°21'3.4"N 76°20'44.7"W and used as antenna a single-mast antenna with a height of 219.45 meters (720 ft), which was demolished in 2011. The broadcast had the mechanical sound of early speech synthesis systems but the message could be clearly understood, with time ticks in the background and a continuous announcement akin to the speaking clock: The recording was changed to "good morning" or "good afternoon" at the appropriate times of day.) Utilizing the world's first all-solid state, 50,000-watt, radio transmitter built by Westinghouse, the signal covered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HANDEL
George Frideric (or Frederick) Handel (; baptised , ; 23 February 1685 – 14 April 1759) was a German-British Baroque composer well known for his operas, oratorios, anthems, concerti grossi, and organ concertos. Handel received his training in Halle and worked as a composer in Hamburg and Italy before settling in London in 1712, where he spent the bulk of his career and became a naturalised British subject in 1727. He was strongly influenced both by the middle-German polyphonic choral tradition and by composers of the Italian Baroque. In turn, Handel's music forms one of the peaks of the "high baroque" style, bringing Italian opera to its highest development, creating the genres of English oratorio and organ concerto, and introducing a new style into English church music. He is consistently recognized as one of the greatest composers of his age. Handel started three commercial opera companies to supply the English nobility with Italian opera. In 1737, he had a physical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Four Minute Warning
The four-minute warning was a public alert system conceived by the British Government during the Cold War and operated between 1953 and 1992. The name derived from the approximate length of time from the point at which a Soviet nuclear missile attack against the United Kingdom could be confirmed and the impact of those missiles on their targets. The population was to be notified by means of air raid sirens, television and radio, and urged to seek cover immediately. In practice, the warning would have been more likely three minutes or less. The warning system Basic details The warning would be initiated by the detection of inbound missiles and aircraft targeted at the United Kingdom. Early in the Cold War, Jodrell Bank was used to detect and track incoming missiles, while continuing to be used for astronomical research. Throughout the Cold War, there was a conflict between the Royal Air Force and the Home Office about who was in charge of the warning system. This wa ...

Emergency Broadcast System
The Emergency Broadcast System (EBS), sometimes called the Emergency Broadcasting System or the Emergency Action Notification System (EANS), was an emergency warning system used in the United States. It replaced the previous CONELRAD system and was used from 1963 to 1997, at which point it was replaced by the Emergency Alert System. Purpose The system was established to provide the President of the United States with an expeditious method of communicating with the American public in the event of war, threat of war, or grave national crisis. The Emergency Broadcast System replaced CONELRAD on August 5, 1963. In later years, it was expanded for use during peacetime emergencies at the state and local levels. Although the system was never used for a national emergency, it was activated more than 20,000 times between 1976 and 1996 to broadcast civil emergency messages and warnings of severe weather hazards. National Level EBS An order to activate the EBS at the national level ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wartime Broadcasting Service
The Wartime Broadcasting Service is a service of the BBC that is intended to broadcast in the United Kingdom either after a nuclear attack or if conventional bombing destroyed regular BBC facilities in a conventional war. It is unclear if the Wartime Broadcasting Service is still operational as plans are kept mainly secretly with the BBC and government officials. According to an article by the BBC, recordings of a nuclear attack warning are still re-recorded and kept up to date periodically. Origins and history The origins of the service lie in pre-World War II plans to disperse BBC staff to facilities such as Wood Norton to guarantee due functioning of the corporation if cities such as London, Belfast, Cardiff, Glasgow and Edinburgh were attacked by the Luftwaffe. In the post-war era, plans were revised so that the Wartime Broadcasting Service would have coped with a nuclear strike by installing 54 low-powered transmitters and keeping (what remained of) the main transmitt ...

Cold War History Of The United States
Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjective perception. A lower bound to temperature is absolute zero, defined as 0.00K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to on the Celsius scale, on the Fahrenheit scale, and on the Rankine scale. Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in the classical sense. The object could be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absolute zero, because ...
