Kirk O' Shotts Transmitter
The Kirk o' Shotts transmitting station is a broadcasting and telecommunications site at The Hirst which lies just outside the village of Salsburgh which is near the town of Shotts in North Lanarkshire central Scotland. (Kirk o' Shotts means 'Church of Shotts' and takes its name from nearby Kirk o' Shotts Parish Church and Kirk o' Shotts Primary School both located as you enter the nearby village of Salsburgh.) History Construction It was built by BICC. Transmission The BBC 405-line television service in Scotland started from Kirk o' Shotts on 14 March 1952 using low power reserve transmitters ( Marconi). Full service began on 17 August 1952 using the main high power transmitters (Vision EMI Type 5704, Sound STC Type CTS-12). The station provided a service to a potential 4.1 million viewers and operated on Channel 3 (Vision 56.75 MHz, Sound 53.25 MHz) and transmissions were vertically polarised. It subsequently became the main national FM transmitting station for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salsburgh
Salsburgh is a semi-rural former coal mining village in greenbelt farmland within the district of North Lanarkshire, Scotland. The closest major towns to the village are Shotts, southeast, and Airdrie northwest. Salsburgh is perhaps best known for the floodlit Kirk O' Shotts Church, which sits on a hillock and is fairly visible as visitors enter the village from the east on the B7066 Whitburn to Newhouse road. As well as the busy M8 Motorway which runs adjacent to the B7066 and gives the Church the affectionate title 'The M8 Church'. Founding There has been a community in the area for over 600 years, although the present village dates back to 1729. At that time only a row of four houses existed, named "Muirhall, Girdhimstrait, Merchanthall and Craighead". Craighead was home to a Mr. Young and his wife Sally, and when Young sold some of his land to construct more houses it was decided that it would be named "Sallysburgh". Through time the name was shortened to Salsburgh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FM Broadcasting
FM broadcasting is a method of radio broadcasting that uses frequency modulation (FM) of the radio broadcast carrier wave. Invented in 1933 by American engineer Edwin Armstrong, wide-band FM is used worldwide to transmit high fidelity, high-fidelity sound over broadcast radio. FM broadcasting offers higher fidelity—more accurate reproduction of the original program sound—than other broadcasting techniques, such as AM broadcasting. It is also less susceptible to Electromagnetic interference, common forms of interference, having less static and popping sounds than are often heard on AM. Therefore, FM is used for most broadcasts of music and general audio (in the audio spectrum). FM radio stations use the very high frequency range of radio frequency, radio frequencies. Broadcast bands Throughout the world, the FM broadcast band falls within the VHF part of the radio spectrum. Usually 87.5 to 108.0 MHz is used, or some portion of it, with few exceptions: * In the Commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

BBC One Scotland
BBC One Scotland is a Scottish free-to-air television channel owned and operated by BBC Scotland. It is the Scottish variation of the UK-wide BBC One network and is broadcast from Pacific Quay in Glasgow. History The BBC Television Service started broadcasts to Scotland on 14 March 1952 using the 405-line television system broadcast from the Kirk o'Shotts transmitter, four weeks after England saw television pictures from Scotland with the funeral of King George VI on 15 February. The first programme, ''Television Comes to Scotland'', was relayed on the English transmitters, featuring a dedicatory prayer, a vote of thanks from Lord Provost of Edinburgh and a ten-minute dancing segment. The inaugural speeches didn't go well in London, but the entertainment output over time received praise. The '' Television Newsreel'' that day was led by the launch of the service in Scotland. Expansion of the service was first planned in 1954 with the building of a transmitter in Inverness; acco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Radio Masts And Towers
Radio masts and towers are typically tall structures designed to support antenna (radio), antennas for telecommunications and broadcasting, including television. There are two main types: guyed and self-supporting structures. They are among the tallest human-made structures. Masts are often named after the broadcasting organizations that originally built them or currently use them. A mast radiator or radiating tower is one in which the metal mast or tower itself is energized and functions as the transmitting antenna. Terminology The terms "mast" and "tower" are often used interchangeably. However, in structural engineering terms, a tower is a self-supporting or cantilevered structure, while a Guyed mast, mast is held up by stays or guy-wires. ; A ''mast'': is a guyed mast, a thin structure without the shear strength to stand unsupported, that uses attached guy lines for stability. They may be mounted on the ground or on top of buildings. Typical ''masts'' are of steel latt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Hill Transmitting Station
The Black Hill transmitting station is a facility for FM and TV broadcasting at Black Hill (), on Duntilland Road, Salsburgh, North Lanarkshire, Scotland which is near the town of Airdrie. It has a guyed mast tall, bringing the antennas to a height of above sea level. This transmitter covers the whole of central Scotland including Edinburgh and Glasgow. History Construction It was built by BICC for the Independent Television Authority (ITA), in 1957 and is now owned and operated by Arqiva. The present mast is the second to have been built at the site. The first, built in 1957 brought the Independent Television service to Central Scotland and opened for service on 31 August 1957. However, complex anomalies in the behaviour of the antenna caused its performance to be less than predicted, and the decision was taken in 1959 to replace the mast with a higher structure and a more conventional aerial on the outside of the mast rather than inside as had been the case with the first ...

Polarization (waves)
, or , is a property of transverse waves which specifies the geometrical orientation of the oscillations. In a transverse wave, the direction of the oscillation is perpendicular to the direction of motion of the wave. One example of a polarized transverse wave is vibrations traveling along a taut string, for example, in a musical instrument like a guitar string. Depending on how the string is plucked, the vibrations can be in a vertical direction, horizontal direction, or at any angle perpendicular to the string. In contrast, in longitudinal waves, such as sound waves in a liquid or gas, the displacement of the particles in the oscillation is always in the direction of propagation, so these waves do not exhibit polarization. Transverse waves that exhibit polarization include electromagnetic waves such as light and radio waves, gravitational waves, and transverse sound waves ( shear waves) in solids. An electromagnetic wave such as light consists of a coupled oscillating el ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
