Redruth Transmitting Station
There are three Redruth transmitting stations: Redruth (Four Lanes) A broadcasting and telecommunications facility in west Cornwall (, ). It includes a high guyed steel lattice mast with square cross section, which is surmounted by the television transmitting antennas, bringing the overall height of the structure to . It is owned and operated by Arqiva. It transmits DVB television, FM radio and DAB radio (and previously, UHF Analogue television signals). It is sometimes referred to as Four Lanes, because of the proximity of the mast to neighbouring village of the same name. The main mast is lit with four bright red aircraft warning lights, a statutory requirement of the Civil Aviation Authority. Redruth (Lanner) A broadcasting transmitter at Lanner Hill (, ). It transmits mediumwave radio signals. It was built in 1942 by German POWs. It is sometimes referred to as ''Redruth MF'', short for Redruth Medium Frequency (Medium Wave). It is owned and run by Arqiva. Redruth (Ca ... [...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.

Absolute Radio
Absolute Radio is a British National radio station owned and operated by Bauer as part of the Absolute Radio Network. It broadcasts nationally across the UK via Digital audio broadcasting and on 1215 kHz MW. History 1993–1997: Virgin Radio launch and early years The Broadcasting Act 1990 allowed for the launch of independent national radio (INR) stations in the United Kingdom. The Radio Authority was mandated to award three INR licences, one of which (INR1) had to be for a "non-pop" station (which was awarded to Classic FM), and one of which had to be for a predominantly speech-based service (this would be advertised later as INR3 and would be awarded to Talk Radio). The remaining licence was to be open to "all-comers". The licences were to be awarded to the highest cash bidder, providing that the applicant met criteria set down in the Broadcasting Act. The second national licence, INR2, would take over the 1197 kHz and 1215 kHz frequencies, which were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

BT Group
BT Group plc (trading as BT and formerly British Telecom) is a British multinational telecommunications holding company headquartered in London, England. It has operations in around 180 countries and is the largest provider of fixed-line, broadband and mobile services in the UK, and also provides subscription television and IT services. BT's origins date back to the founding in 1846 of the Electric Telegraph Company, the world's first public telegraph company, which developed a nationwide communications network. BT Group as it came to be started in 1912, when the General Post Office, a government department, took over the system of the National Telephone Company becoming the monopoly telecoms supplier in the United Kingdom. The Post Office Act of 1969 led to the GPO becoming a public corporation. The ''British Telecom'' brand was introduced in 1980, and became independent of the Post Office in 1981, officially trading under the name. British Telecommunications was privatised ...

Microwave
Microwave is a form of electromagnetic radiation with wavelengths ranging from about one meter to one millimeter corresponding to frequencies between 300 MHz and 300 GHz respectively. Different sources define different frequency ranges as microwaves; the above broad definition includes both UHF and EHF (millimeter wave) bands. A more common definition in radio-frequency engineering is the range between 1 and 100 GHz (wavelengths between 0.3 m and 3 mm). In all cases, microwaves include the entire SHF band (3 to 30 GHz, or 10 to 1 cm) at minimum. Frequencies in the microwave range are often referred to by their IEEE radar band designations: S, C, X, Ku, K, or Ka band, or by similar NATO or EU designations. The prefix ' in ''microwave'' is not meant to suggest a wavelength in the micrometer range. Rather, it indicates that microwaves are "small" (having shorter wavelengths), compared to the radio waves used prior to microwave te ...

Medium Wave
Medium wave (MW) is the part of the medium frequency (MF) radio band used mainly for AM radio broadcasting. The spectrum provides about 120 channels with more limited sound quality than FM stations on the FM broadcast band. During the daytime, reception is usually limited to more local stations, though this is dependent on the signal conditions and quality of radio receiver used. Improved signal propagation at night allows the reception of much longer distance signals (within a range of about 2,000 km or 1,200 miles). This can cause increased interference because on most channels multiple transmitters operate simultaneously worldwide. In addition, amplitude modulation (AM) is often more prone to interference by various electronic devices, especially power supplies and computers. Strong transmitters cover larger areas than on the FM broadcast band but require more energy and longer antennas. Digital modes are possible but have not reached momentum yet. MW was the main radio ban ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
POWs
A prisoner of war (POW) is a person who is held captive by a belligerent power during or immediately after an armed conflict. The earliest recorded usage of the phrase "prisoner of war" dates back to 1610. Belligerents hold prisoners of war in custody for a range of legitimate and illegitimate reasons, such as isolating them from the enemy combatants still in the field (releasing and repatriating them in an orderly manner after hostilities), demonstrating military victory, punishing them, prosecuting them for war crimes, exploiting them for their labour, recruiting or even conscripting them as their own combatants, collecting military and political intelligence from them, or indoctrinating them in new political or religious beliefs. Ancient times For most of human history, depending on the culture of the victors, enemy fighters on the losing side in a battle who had surrendered and been taken as prisoners of war could expect to be either slaughtered or enslaved.
