Capital Radio (pirate)
{{no footnotes, date=April 2012 Capital Radio (not to be confused with Capital Radio, the later British radio station of the same name) was a pirate radio station which operated from international waters off the coast of the Netherlands in 1970. The station was set up by Canada, Canadian idealist Tim Thomason. In 1965 Thomason had established the International Broadcasting Society with the intention of bringing together professional broadcasting organisations from around the world. Eventually Thomason decided that the Society should have its own radio station which could be used to broadcast messages from the participating organisations. Thomason and his associates acquired a former Germany, German Coastal trading vessel, coaster and renamed it the ''MV King David'', because they saw the station as being a David to the major broadcasters' Goliath (Bible), Goliath. The ship was registered in Liechtenstein, becoming unofficially the only member of the tiny, doubly landlocked country' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Capital Radio
Capital London is a radio station owned and operated by the Global media company as part of its national Capital FM Network. As Capital Radio it was launched in the London area in 1973 as one of Britain's first two commercial radio stations. Its brief was to entertain, while its opposite number, London Broadcasting (LBC), was licensed to provide news and information. In search of a larger audience in 1974, Capital Radio rapidly moved from a general and entertainment station with drama, features, documentaries and light music to a more successful pop music-based format. In 1988 it became two stations: 95.8 Capital FM and Capital Gold. After some national expansion with the purchase of other radio stations the Capital Radio Group merged with GWR Group in 2005 to form GCap Media which in turn was taken over by Global Radio in 2008. In 2011 Capital was launched nationally, apart from the daily breakfast and weekday drivetime shows, becoming part of the Capital FM Network. In 2019 ...

Canal
Canals or artificial waterways are waterways or engineered channels built for drainage management (e.g. flood control and irrigation) or for conveyancing water transport vehicles (e.g. water taxi). They carry free, calm surface flow under atmospheric pressure, and can be thought of as artificial rivers. In most cases, a canal has a series of dams and locks that create reservoirs of low speed current flow. These reservoirs are referred to as ''slack water levels'', often just called ''levels''. A canal can be called a ''navigation canal'' when it parallels a natural river and shares part of the latter's discharges and drainage basin, and leverages its resources by building dams and locks to increase and lengthen its stretches of slack water levels while staying in its valley. A canal can cut across a drainage divide atop a ridge, generally requiring an external water source above the highest elevation. The best-known example of such a canal is the Panama Canal. Many ...

Surface Wave
In physics, a surface wave is a mechanical wave that propagates along the Interface (chemistry), interface between differing media. A common example is gravity waves along the surface of liquids, such as ocean waves. Gravity waves can also occur within liquids, at the interface between two fluids with different densities. Elastic surface waves can travel along the surface of solids, such as ''Rayleigh wave, Rayleigh'' or ''Love wave, Love'' waves. Electromagnetic waves can also propagate as "surface waves" in that they can be guided along with a refractive index gradient or along an interface between two media having different dielectric constants. In radio transmission (telecommunications), transmission, a ''ground wave'' is a guided wave that propagates close to the surface of the Earth. Mechanical waves In seismology, several types of surface waves are encountered. Surface waves, in this mechanical sense, are commonly known as either ''Love waves'' (L waves) or ''Rayleigh ...

Skywave
In radio communication, skywave or skip refers to the propagation of radio waves reflected or refracted back toward Earth from the ionosphere, an electrically charged layer of the upper atmosphere. Since it is not limited by the curvature of the Earth, skywave propagation can be used to communicate beyond the horizon, at intercontinental distances. It is mostly used in the shortwave frequency bands. As a result of skywave propagation, a signal from a distant AM broadcasting station, a shortwave station, or – during sporadic E propagation conditions (principally during the summer months in both hemispheres) a distant VHF FM or TV station – can sometimes be received as clearly as local stations. Most long-distance shortwave (high frequency) radio communication – between 3 and 30 MHz – is a result of skywave propagation. Since the early 1920s amateur radio operators (or "hams"), limited to lower transmitter power than broadcast stations, have ta ...

Antenna (radio)
In radio engineering, an antenna or aerial is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver. In transmission, a radio transmitter supplies an electric current to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic wave In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic (EM) field, which propagate through space and carry momentum and electromagnetic radiant energy. It includes radio waves, microwaves, infrared, (visib ...s (radio waves). In Receiver (radio), reception, an antenna intercepts some of the power of a radio wave in order to produce an electric current at its terminals, that is applied to a receiver to be Amplifier, amplified. Antennas are essential components of all radio equipment. An antenna is an array of conductor (material), conductors (Driven element, elements), elect ...

Radio 270
Radio 270 was a pirate radio station serving Yorkshire and the North East of England from 1966 to 1967. It broadcast from a converted Dutch lugger called ''Oceaan 7'' positioned in international waters off Scarborough, North Yorkshire followed by a move to a more sheltered position off Bridlington. Origins In 1965 a group of Yorkshire businessmen formed a consortium to establish an offshore radio station to broadcast to the North East coast from a location off Scarborough. Don Robinson, aged 28, who was an entertainments promoter, began the venture with Bill Pashby (a fishing boat skipper), Roland Hill (a poultry farmer) and Leonard Dale (owner of the Dale Electrics business at Gristhorpe). These recruited Wilf Proudfoot, owner of a chain of supermarkets and a former Conservative MP. The venture was incorporated within a public company named Ellambar Investments Ltd. In late 1965, Proudfoot addressed a public meeting at a Scarborough hotel in which he invited the public to subs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transmitter
In electronics and telecommunications, a radio transmitter or just transmitter is an electronic device which produces radio waves with an antenna (radio), antenna. The transmitter itself generates a radio frequency alternating current, which is applied to the Antenna (radio), antenna. When excited by this alternating current, the antenna radiates radio waves. Transmitters are necessary component parts of all electronic devices that communicate by radio communication, radio, such as radio broadcasting, radio and television broadcasting stations, cell phones, walkie-talkies, Wireless LAN, wireless computer networks, Bluetooth enabled devices, garage door openers, two-way radios in aircraft, ships, spacecraft, radar sets and navigational beacons. The term ''transmitter'' is usually limited to equipment that generates radio waves for Communication engineering, communication purposes; or radiolocation, such as radar and navigational transmitters. Generators of radio waves for heatin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kilowatt
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). : ...

Latin America
Latin America or * french: Amérique Latine, link=no * ht, Amerik Latin, link=no * pt, América Latina, link=no, name=a, sometimes referred to as LatAm is a large cultural region in the Americas where Romance languages — languages derived from Latin — are predominantly spoken. The term was coined in the nineteenth century, to refer to regions in the Americas that were ruled by the Spanish, Portuguese and French empires. The term does not have a precise definition, but it is "commonly used to describe South America, Central America, Mexico, and the islands of the Caribbean." In a narrow sense, it refers to Spanish America plus Brazil (Portuguese America). The term "Latin America" is broader than categories such as ''Hispanic America'', which specifically refers to Spanish-speaking countries; and ''Ibero-America'', which specifically refers to both Spanish and Portuguese-speaking countries while leaving French and British excolonies aside. The term ''Latin America'' was f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Country And Western
A country is a distinct part of the world, such as a state, nation, or other political entity. It may be a sovereign state or make up one part of a larger state. For example, the country of Japan is an independent, sovereign state, while the country of Wales is a component of a multi-part sovereign state, the United Kingdom. A country may be a historically sovereign area (such as Korea), a currently sovereign territory with a unified government (such as Senegal), or a non-sovereign geographic region associated with certain distinct political, ethnic, or cultural characteristics (such as the Basque Country). The definition and usage of the word "country" is flexible and has changed over time. ''The Economist'' wrote in 2010 that "any attempt to find a clear definition of a country soon runs into a thicket of exceptions and anomalies." Most sovereign states, but not all countries, are members of the United Nations. The largest country by area is Russia, while the smallest is ...

Pop Music
Pop music is a genre of popular music that originated in its modern form during the mid-1950s in the United States and the United Kingdom. The terms ''popular music'' and ''pop music'' are often used interchangeably, although the former describes all music that is popular and includes many disparate styles. During the 1950s and 1960s, pop music encompassed rock and roll and the youth-oriented styles it influenced. ''Rock'' and ''pop'' music remained roughly synonymous until the late 1960s, after which ''pop'' became associated with music that was more commercial, ephemeral, and accessible. Although much of the music that appears on record charts is considered to be pop music, the genre is distinguished from chart music. Identifying factors usually include repeated choruses and hooks, short to medium-length songs written in a basic format (often the verse-chorus structure), and rhythms or tempos that can be easily danced to. Much pop music also borrows elements from other styles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
