Egypt has long been the cultural and informational centre of the Middle East and North Africa, and Cairo is the region's largest publishing and broadcasting centre.
In the Seychelles, local and international telecommunications lines are operated by Cable & Wireless. In 1997 there were around 11,000 telephone lines and in excess of 20,000 telephones, meaning that over half of the population have a home telephone. Digital microwave systems were introduced to the Seychelles in 1992 and Cable & Wireless offers other services from its Seychelles radio coast station. Direct international calls are available to over 100 countries worldwide.
Shortwave radio is radio transmission using shortwave radio frequencies. There is no official definition of the band, but the range always includes all of the high frequency band (HF), and generally extends from 30–3 MHz ; above the medium frequency band (MF), to the end of the HF band.
BBC Radio 4 is a radio station owned and operated by the British Broadcasting Corporation (BBC) that broadcasts a wide variety of spoken-word programmes including news, drama, comedy, science and history. It replaced the BBC Home Service in 1967. The station controller is Gwyneth Williams, and the station is part of BBC Radio and the BBC Radio department. The station is broadcast from the BBC's headquarters at Broadcasting House, London. On 21 January 2019 Williams announced she was quitting the role. There are no details of when or who will be her replacement.
Medium wave (MW) is the part of the medium frequency (MF) radio band used mainly for AM radio broadcasting. For Europe the MW band ranges from 526.5 kHz to 1606.5 kHz, using channels spaced every 9 kHz, and in North America an extended MW broadcast band ranges from 525 kHz to 1705 kHz, using 10 kHz spaced channels. The term is a historic one, dating from the early 20th century, when the radio spectrum was divided on the basis of the wavelength of the waves into long wave (LW), medium wave, and short wave (SW) radio bands.
Radio broadcasting is transmission by radio waves intended to reach a wide audience. Stations can be linked in radio networks to broadcast a common radio format, either in broadcast syndication or simulcast or both. The signal types can be either analog audio or digital audio.
High frequency (HF) is the ITU designation for the range of radio frequency electromagnetic waves between 3 to 30 megahertz (MHz). It is also known as the decameter band or decameter wave as its wavelengths range from one to ten decameters. Frequencies immediately below HF are denoted medium frequency (MF), while the next band of higher frequencies is known as the very high frequency (VHF) band. The HF band is a major part of the shortwave band of frequencies, so communication at these frequencies is often called shortwave radio. Because radio waves in this band can be reflected back to Earth by the ionosphere layer in the atmosphere – a method known as "skip" or "skywave" propagation – these frequencies are suitable for long-distance communication across intercontinental distances and for mountainous terrains which prevent line-of-sight communications. The band is used by international shortwave broadcasting stations (2.31–25.82 MHz), aviation communication, government time stations, weather stations, amateur radio and citizens band services, among other uses.
BBC Radio 5 Live is the BBC's national radio service that broadcasts mainly news, sport, discussion, interviews and phone-ins. It is the principal radio station covering sport in the United Kingdom, broadcasting virtually all major sports events staged in the UK or involving British competitors.
In radio communication, skywave or skip refers to the propagation of radio waves reflected or refracted back toward Earth from the ionosphere, an electrically charged layer of the upper atmosphere. Since it is not limited by the curvature of the Earth, skywave propagation can be used to communicate beyond the horizon, at intercontinental distances. It is mostly used in the shortwave frequency bands.
Sveriges Radio AB is Sweden's national publicly funded radio broadcaster. Sveriges Radio is a public limited company, owned by an independent foundation, previously funded through a licensing fee, the level of which is decided by the Swedish Riksdag. As of January 1 2019, the funds stem from standard taxation. No advertising is permitted. Its legal status could be described as that of a quasi-autonomous non-governmental organization.
96.4 The Wave is a British Independent Local Radio station that serves the Swansea Bay area of West Wales. The station is owned by Bauer Radio and mainly broadcasts chart and contemporary music, alongside news and local information, for an audience of under 40s.
Polskie Radio Spółka Akcyjna is Poland's state-owned national public-service radio broadcasting organization.
WXB 102 is a former Metro Manila FM radio station and current Internet radio station that plays new wave, punk rock, synthpop, electronic music, dance-punk, post-punk, classic alternative rock and more from the UK, US, Philippines and the rest of the world, which was available through Live365, Hayag.com and Ustream.tv, and now via Mixlr.
WLHH is a classic hits radio station licensed to Ridgeland, South Carolina, with studios in Hilton Head and transmitter located between Ridgeland and Beaufort.
The mass media in Ethiopia consist of radio, television and the Internet, which remain under the control of the Ethiopian government, as well as private newspapers and magazines. Ten radio broadcast stations, eight AM and two shortwave, are licensed to operate in Ethiopia. The major radio broadcasting stations include Raido Ethiopia, Radio Fana a private station, Radio Voice of One Free Ethiopia, and the Voice of the Revolution of Tigray. The only terrestrial (broadcast) television networks are government owned and include Ethiopian Television and other regional stations. In keeping with government policy, radio broadcasts occur in a variety of languages including Amharic, Afaan Oromo, Tigrigna, and more. There are also many video sharing websites which are a popular way of getting information as well as entertainment in Ethiopia.
KXRX is the call sign of the radio station 97 Rock based in Pasco, Washington. The frequency is 97.1 MHz, and it is a Townsquare Media radio station. The call letters are based on the former KXRX/Seattle—a major rock radio station active in Seattle from 1987-1994 on 96.5 FM and now known as The X KXRX, an internet only active rock station.
NPO Radio 5 is a Dutch public-service network radio station operated by NPO. Its main format is classic hits from the 1950s and beyond, with a much stronger emphasis from the 1960s to 1980s. Very rarely, songs from the late-1940s may air at times. The service targets 55 year olds and older, in contrast to that of Radio 2 (35-55) and FunX (15-35).
The following outline is provided as an overview of and topical guide to radio:
Radio is the technology of signaling or communicating using radio waves. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by a radio receiver connected to another antenna. Radio is very widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking and satellite communication among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal in the transmitter. In radar, used to locate and track objects like aircraft, ships, spacecraft and missiles, a beam of radio waves emitted by a radar transmitter reflects off the target object, and the reflected waves reveal the object's location. In radio navigation systems such as GPS and VOR, a mobile receiver receives radio signals from navigational radio beacons whose position is known, and by precisely measuring the arrival time of the radio waves the receiver can calculate its position on Earth. In wireless remote control devices like drones, garage door openers, and keyless entry systems, radio signals transmitted from a controller device control the actions of a remote device.
