Llanidloes Transmitting Station
The Llanidloes transmitting station is a broadcasting and telecommunications facility consisting of a self-supporting 23 m lattice mast erected on land that is itself about 245 m above sea level about 1 km to the west of the town of Llanidloes in Powys, Wales. It was originally built by the BBC, entering service just before Christmas 1966 transmitting the now-defunct 405-line VHF television system. Transmissions of the original three FM radio services began in February 1967. Currently, the transmitter provides DVB-T digital television to the area, along with FM radio. With only 2 W ERP, the television broadcasts only cover the town of Llanidloes to the east, the radio broadcasts reach somewhat further east along the Severn valley towards Llandinam. Specifications and history As built, the 405-line television and VHF FM radio services came (indirectly) from Wenvoe near Cardiff, and this site was therefore classed as a relay of Wenvoe. UHF television was adde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Long Mountain Transmitting Station
The Long Mountain transmitting station is sited on a ridge about east of Welshpool in Powys, Mid Wales and has been broadcasting UHF terrestrial TV and VHF FM radio services since the late 1970s. The site has a self-supporting 170' (52 metre) high lattice steel mast and was fed with an SHF link from Blaenplwyf via Llangurig. Despite not taking its signal off-air, it was originally classed as a 625-line UHF TV relay of Blaenplwyf. The transmitter originally radiated 1 kW providing TV and radio to an area including Newtown and Oswestry. Being only from the England/Wales border, coverage extended to several towns in England – Shrewsbury included. Long Mountain became re-classed as main transmitter in its own right (albeit a very low power one) with the advent of digital terrestrial TV from the site on 4 November 2009. In addition to this, it currently transmits FM radio and a single multiplex of DAB Digital radio. Services available Analogue television 17 Septem ...

Super High Frequency
Super high frequency (SHF) is the ITU designation for radio frequencies (RF) in the range between 3 and 30 gigahertz (GHz). This band of frequencies is also known as the centimetre band or centimetre wave as the wavelengths range from one to ten centimetres. These frequencies fall within the microwave band, so radio waves with these frequencies are called microwaves. The small wavelength of microwaves allows them to be directed in narrow beams by aperture antennas such as parabolic dishes and horn antennas, so they are used for point-to-point communication and data links This article from the beginning of the microwave era predicted the future value of microwaves for point-to-point communication. and for radar. This frequency range is used for most radar transmitters, wireless LANs, satellite communication, microwave radio relay links, satellite phones (S band), and numerous short range terrestrial data links. They are also used for heating in industrial microwave h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Frequency Modulation
Frequency modulation (FM) is a signal modulation technique used in electronic communication, originally for transmitting messages with a radio wave. In frequency modulation a carrier wave is varied in its instantaneous frequency in proportion to a property, primarily the instantaneous amplitude, of a message signal, such as an audio signal. The technology is used in telecommunications, radio broadcasting, signal processing, and Run-length limited#FM: .280.2C1.29 RLL, computing. In Analog signal, analog frequency modulation, such as radio broadcasting of voice and music, the instantaneous frequency deviation, i.e. the difference between the frequency of the carrier and its center frequency, has a functional relation to the modulating signal amplitude. Digital data can be encoded and transmitted with a type of frequency modulation known as frequency-shift keying (FSK), in which the instantaneous frequency of the carrier is shifted among a set of frequencies. The frequencies m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
