Whitehawk Hill Transmitting Station
The Whitehawk Hill transmitting station (also known as the Whitehawk transmitting station) is a broadcasting and telecommunications facility located at Whitehawk, an eastern suburb of Brighton in the English city of Brighton and Hove. It is the city's main transmission facility for television and radio signals. It broadcasts digital television, FM and DAB radio to the coastal city of Brighton and Hove and to surrounding areas along the Sussex coast. It stopped broadcasting analogue television when the digital switchover occurred locally in March 2012. Services broadcast include BBC One ( South East), BBC Two, ITV ( Meridian), Channel 4, BBC national radio stations, BBC Sussex and Heart Sussex. History A radar station was opened on the high ground of Whitehawk Hill, to the east of central Brighton, during World War II. Meanwhile, television broadcasts first reached the town in 1953 when a relay transmitter was erected on Truleigh Hill, several miles to the west on the South ...

BBC South East
BBC South East is the BBC English region serving Kent, East Sussex, most parts of West Sussex and southern parts of Surrey. The BBC region was created in September 2001 by the joining of the Heathfield transmitter (formerly part of the BBC South region) with the Bluebell Hill and Dover transmitters (from the then BBC London and South East region) to form a new regional TV service. Unlike ITV Meridian (East), it does not serve southern Essex (received from a Bluebell Hill overlap), this area being part of the BBC London region instead. Services Television BBC South East's television output consists of the flagship regional news service ''South East Today'' and its main programme is broadcast weeknights at 6:30 pm, with short bulletins throughout the day and during the weekend. A half-hour opt-out during ''Sunday Politics'' is produced by an independent production company. In 2020, ''South East Today'' joined forces with '' BBC London News'' during the COVID-19 Pandemic to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whitehawk Hill
Whitehawk Hill is a Local Nature Reserve in Brighton, East Sussex. It is owned and managed by Brighton and Hove City Council. At the top of the hill is Whitehawk Camp, a Neolithic causewayed enclosure which is a Scheduled Monument. This is species-rich chalk grassland which has views over Brighton and the sea, together with the Isle of Wight on clear days. There are colonies of chalkhill blue The chalkhill blue (''Lysandra coridon'') is a butterfly in the family Lycaenidae. It is a small butterfly that can be found throughout the Palearctic realm, where it occurs primarily in grasslands rich in chalk. Males have a pale blue colour, wh ... butterflies.

Ovingdean
Ovingdean is a small, formerly agricultural, village in the east of Brighton and Hove, East Sussex, England. Overview It was absorbed into the administrative borough of Brighton, East Sussex, England in 1928, and now forms part of the city of Brighton and Hove. It has expanded through the growth of residential streets on its eastern and southern sides, and now has a population of about 1,200. Some of the current housing replaces earlier shacks of the type once found in neighbouring Woodingdean and Peacehaven, built after the First World War. It almost abuts Rottingdean to the south-east and Woodingdean to the north-east, but still has open downland on its other sides, on which may be found a golf course and Brighton racecourse as well as some residual farmland. The name, which is Old English for 'the valley of people associated with a man called Ōfa', shows that the village has existed since Anglo-Saxon times. Little seems to have disturbed its peace since. It is sometimes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patcham
Patcham () is an area of the city of Brighton & Hove, about north of the city centre. It is bounded by the A27 (Brighton bypass) to the north, Hollingbury to the east and southeast, Withdean to the south and the Brighton Main Line to the west. The A23 passes through the area. History Patcham was originally a separate village that developed around the partly 12th- and 13th-century All Saints' Church. The parish of Patcham extended to and encompassed large parts of what are now adjacent suburbs, such as Withdean, Westdene, Hollingbury and Tongdean. It extended eastwards into modern-day Moulsecoomb, westwards beyond Dyke Road into Hove, and northwards across the sparsely-populated South Downs towards the parishes of Pyecombe and Ditchling. The centre of the original village, based around the church (on Church Hill) and the Old London Road – now bypassed by the modern A23 – is a conservation area, and several buildings are listed. Modern Patcham Sir Herbert Carden, a promi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wrotham Transmitting Station
Wrotham ( ) is a village on the Pilgrims' Way in Kent, England, at the foot of the North Downs. It is north of Borough Green and approximately east of Sevenoaks. It is between the M20 and M26 motorways. History The name first occurs as ''Uurotaham'' in the year 788, meaning 'homestead of a man called Wrōta'. The offshoot village on Wrotham Heath at the heart of the heath of the same name, once an area of wholly common land, is to the south-east. Wrotham shows extensive signs of occupation by the Romans and it is posited that the Wrotham Pinot, a disease-resistant variety of the Pinot noir grape found in Wrotham churchyard, is descended from vines brought by the Romans. The church of St George is Early English and later; nearby is the site of a palace of the Archbishop of Canterbury, maintained until the time of Archbishop Simon Islip (c. 1350). Wrotham Hill to the north was a main measuring point for the 18th-century trigonometric survey linking the Greenwich R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stereophonic Sound
Stereophonic sound, or more commonly stereo, is a method of sound reproduction that recreates a multi-directional, 3-dimensional audible perspective. This is usually achieved by using two independent audio channels through a configuration of two loudspeakers (or stereo headphones) in such a way as to create the impression of sound heard from various directions, as in natural hearing. Because the multi-dimensional perspective is the crucial aspect, the term ''stereophonic'' also applies to systems with more than two channels or speakers such as quadraphonic and surround sound. Binaural sound systems are also ''stereophonic''. Stereo sound has been in common use since the 1970s in entertainment media such as broadcast radio, recorded music, television, video cameras, cinema, computer audio, and internet. Etymology The word ''stereophonic'' derives from the Greek (''stereós'', "firm, solid") + (''phōnḗ'', "sound, tone, voice") and it was coined in 1927 by Wester ...

Monaural
Monaural or monophonic sound reproduction (often shortened to mono) is sound intended to be heard as if it were emanating from one position. This contrasts with stereophonic sound or ''stereo'', which uses two separate audio channels to reproduce sound from two microphones on the right and left side, which is reproduced with two separate loudspeakers to give a sense of the direction of sound sources. In mono, only one loudspeaker is necessary, but, when played through multiple loudspeakers or headphones, identical signals are fed to each speaker, resulting in the perception of one-channel sound "imaging" in one sonic space between the speakers (provided that the speakers are set up in a proper symmetrical critical-listening placement). Monaural recordings, like stereo ones, typically use multiple microphones fed into multiple channels on a recording console, but each channel is " panned" to the center. In the final stage, the various center-panned signal paths are usually mixed d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ultra High Frequency
Ultra high frequency (UHF) is the ITU designation for radio frequencies in the range between 300 megahertz (MHz) and 3 gigahertz (GHz), also known as the decimetre band as the wavelengths range from one meter to one tenth of a meter (one decimeter). Radio waves with frequencies above the UHF band fall into the super-high frequency (SHF) or microwave frequency range. Lower frequency signals fall into the VHF (very high frequency) or lower bands. UHF radio waves propagate mainly by line of sight; they are blocked by hills and large buildings although the transmission through building walls is strong enough for indoor reception. They are used for television broadcasting, cell phones, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, walkie-talkies, cordless phones, satellite phones, and numerous other applications. The IEEE defines the UHF radar band as frequencies between 300 MHz and 1 GHz. Two other IEEE radar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Very High Frequency
Very high frequency (VHF) is the ITU designation for the range of radio frequency electromagnetic waves ( radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter. Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high frequency (UHF). VHF radio waves propagate mainly by line-of-sight, so they are blocked by hills and mountains, although due to refraction they can travel somewhat beyond the visual horizon out to about 160 km (100 miles). Common uses for radio waves in the VHF band are Digital Audio Broadcasting (DAB) and FM radio broadcasting, television broadcasting, two-way land mobile radio systems (emergency, business, private use and military), long range data communication up to several tens of kilometers with radio modems, amateur radio, and marine communications. Air traffic control communications and air navigation systems (e.g. VOR and ILS ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rowridge Transmitting Station
The Rowridge transmitting station is a facility for FM radio and television transmission at Rowridge on the Isle of Wight in southern England. It currently has a tall guyed mast, owned and operated by Arqiva (previously National Grid Wireless). There is a smaller tower on the site belonging to British Telecom. Prior to Digital Switchover (DSO) the station broadcast with a power of 250 kW ( ERP) for FM radio, 500 kW for analogue television, and 20 kW for digital television. In July 2007, Ofcom confirmed that Rowridge would remain an A Group transmitter at Digital switchover; the digital television transmission signal was then boosted to 200 kW. From March 2018 MUXES 7 & 8 moved out of the A group to channels 55 & 56 (segraph, though these are due to be turned off between 2020 and 2022. Rowridge is one of only two main transmitters (the other is the rather smaller transmitter of Rosneath in Scotland) to broadcast its output on both horizontal and vertica ...

Crystal Palace Transmitting Station
The Crystal Palace transmitting station, officially known as Arqiva Crystal Palace, is a broadcasting and telecommunications site in the Crystal Palace area of the London Borough of Bromley, England (). It is located on the site of the former television station and transmitter operated by John Logie Baird from 1933. The station is the eighth-tallest structure in London, and is best known as the main television transmitter for the London area. As such, it is the most important transmitter in the UK in terms of population covered. The transmitter is owned and operated by Arqiva. History and development The station was constructed in the mid-1950s among the ruins of the Crystal Palace. The Aquarium on whose site it stands was destroyed in 1941 during the demolition of the Palace's north water tower. (John Logie Baird's earlier transmitter and TV studios were a separate development at the other end of the Palace and perished with it in 1936.) Its new tower was the tallest struct ...

South Downs
The South Downs are a range of chalk hills that extends for about across the south-eastern coastal counties of England from the Itchen valley of Hampshire in the west to Beachy Head, in the Eastbourne Downland Estate, East Sussex, in the east. The Downs are bounded on the northern side by a steep escarpment, from whose crest there are extensive views northwards across the Weald. The South Downs National Park forms a much larger area than the chalk range of the South Downs and includes large parts of the Weald. The South Downs are characterised by rolling chalk downland with close-cropped turf and dry valleys, and are recognised as one of the most important chalk landscapes in England. The range is one of the four main areas of chalk downland in southern England. The South Downs are relatively less populated compared to South East England as a whole, although there has been large-scale urban encroachment onto the chalk downland by major seaside resorts, including most notabl ...
