Daventry Transmitting Station
The Daventry transmitting station was a major broadcasting facility located on Borough Hill on the outskirts of Daventry, Northamptonshire. It operated from 1925 until 1992, carrying long-wave, medium-wave, and short-wave broadcasts at different times in its history. In its heyday the site had more than 40 masts and towers on an antenna field extending over hundreds of acres. Since 1992, only DAB services have been broadcast from the site using a single mast. All other antennas have been demolished. Long-wave transmitter During 1923, the British Broadcasting Company's chief engineer, Peter Eckersley, deduced that it would be possible to provide a broadcast service to most of the United Kingdom using a single high-power long-wave transmitter located in central England. A 50-acre site on Borough Hill was acquired by the BBC for this purpose. A T-aerial was suspended between two masts, each 500 ft high and spaced by 800 ft. The Daventry transmitter took over from Chelms ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

British Broadcasting Company
The British Broadcasting Company Ltd. (BBC) was a short-lived British commercial broadcasting company formed on 18 October 1922 by British and American electrical companies doing business in the United Kingdom. Licensed by the British General Post Office, their original office was located on the second floor of Magnet House, the GEC buildings in London and consisted of a room and a small antechamber. On 14 December 1922, John Reith was hired to become the Managing Director of the company at that address. The company later moved its offices to the premises of the Marconi Company. The BBC as a commercial broadcasting company did not sell air time but it did carry a number of sponsored programmes paid for by British newspapers. On 31 December 1926, the company was dissolved, and its assets were transferred to the non-commercial and crown-chartered British Broadcasting Corporation (BBC).

BBC National Programme
The BBC National Programme was a radio service which was on the air from 9 March 1930 â replacing the earlier BBC's experimental station 5XX â until 1 September 1939 when it was subsumed into the Home Service, two days before the outbreak of World War II. Both the National Programme and the Regional Programme provided a mixed mainstream radio service. Whilst the two services provided different programming, allowing listeners a choice they were not streamed to appeal to different audiences, rather they were intended to offer a choice of programming to a single audience. While using the same transmitters, the National Programme broadcast significantly more speech and classical music than its successor, the Light Programme. Similarly, the Regional Programme broadcast much more light and dance music than its successor, the Home Service.

Worcestershire
Worcestershire ( , ; written abbreviation: Worcs) is a county in the West Midlands of England. The area that is now Worcestershire was absorbed into the unified Kingdom of England in 927, at which time it was constituted as a county (see History of Worcestershire). Over the centuries the county borders have been modified, but it was not until 1844 that substantial changes were made. Worcestershire was abolished as part of local government reforms in 1974, with its northern area becoming part of the West Midlands and the rest part of the county of Hereford and Worcester. In 1998 the county of Hereford and Worcester was abolished and Worcestershire was reconstituted, again without the West Midlands area. Location The county borders Herefordshire to the west, Shropshire to the north-west, Staffordshire only just to the north, West Midlands to the north and north-east, Warwickshire to the east and Gloucestershire to the south. The western border with Herefordshire includes a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
T-aerial
A T-antenna, T-aerial, flat-top antenna, or (capacitively) top-loaded antenna is a monopole radio antenna with transverse capacitive loading wires attached to its top. T-antennas are typically used in the VLF, LF, MF, and shortwave bands, and are widely used as transmitting antennas for amateur radio stations, and long wave and medium wave AM broadcasting stations. They can also be used as receiving antennas for shortwave listening. The antenna consists of one or more horizontal wires suspended between two supporting radio masts or buildings and insulated from them at the ends. A vertical wire is connected to the center of the horizontal wires and hangs down close to the ground, connected to the transmitter or receiver. Combined, the two sections form a âTâ shape, hence the name. The transmitter power is applied, or the receiver is connected, between the bottom of the vertical wire and a ground connection. The T-antenna functions as a monopole antenna with capacitive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Digital Audio Broadcasting
Digital radio is the use of digital technology to transmit or receive across the radio spectrum. Digital transmission by radio waves includes digital broadcasting, and especially digital audio radio services. Types In digital broadcasting systems, the analog audio signal is digital audio, digitized, Audio compression (data), compressed using an audio coding format such as AAC+ (MDCT) or MPEG-1 Audio Layer II, MP2, and transmitted using a digital modulation scheme. The aim is to increase the number of radio programs in a given spectrum, to improve the audio quality, to eliminate fading problems in mobile environments, to allow additional datacasting services, and to decrease the transmission power or the number of transmitters required to cover a region. However, analog radio (AM and FM) is still more popular and listening to radio over IP (Internet Protocol) is growing in popularity. In 2012 four digital wireless radio systems are recognized by the International Telecommunicati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Borough Hill
Borough Hill is a hill to the east of the town of Daventry in the English county of Northamptonshire. It is over above sea level and dominates the surrounding area. History Borough Hill has a history of human habitation dating into prehistory. Remains have been found on the hill of two Bronze Age barrows, two Iron Age hillforts, one of which is the fourth largest found in Britain, and a later Roman villa and farming settlement. The hill is designated as a scheduled monument. In 1823, the historian and archaeologist George Baker undertook the first excavation of the site, he discovered the remains of the Roman villa. The site then underwent a full excavation in 1852 by local historian Beriah Botfield who recorded his findings. His notes, manuscripts and some of the antiquities found are now kept at the British Museum. In 1645, Borough Hill was used as a base by the Royalist army of King Charles I, in the week prior to the Battle of Naseby, in which the Royalists were def ...

Radio Masts And Towers
Radio masts and towers are typically tall structures designed to support 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. In the case of a mast radiator or radiating tower, the whole mast or tower is itself 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 mast is held up by stays or guys. Broadcast engineers in the UK use the same terminology. A mast is a ground-based or rooftop structure that supports antennas at a height where they can satisfactorily send or receive radio waves. Typical masts are of steel lattice or tubular steel construction. Masts themselves play no part in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shortwave Radio
Shortwave radio is radio transmission using shortwave (SW) radio frequencies. There is no official definition of the band, but the range always includes all of the high frequency band (HF), which extends from 3 to 30 MHz (100 to 10 metres); above the medium frequency band (MF), to the bottom of the VHF band. Radio waves in the shortwave band can be reflected or refracted from a layer of electrically charged atoms in the atmosphere called the ionosphere. Therefore, short waves directed at an angle into the sky can be reflected back to Earth at great distances, beyond the horizon. This is called skywave or "skip" propagation. Thus shortwave radio can be used for communication over very long distances, in contrast to radio waves of higher frequency, which travel in straight lines ( line-of-sight propagation) and are limited by the visual horizon, about 64 km (40 miles). Shortwave broadcasts of radio programs played an important role in the early days of radi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
