Shortwave radio is radio transmission using radio frequencies in the shortwave bands (SW). There is no official definition of the band range, but it always includes all of the high frequency band (HF), which extends from 3 to 30 MHz ; above the medium frequency band (MF), to the bottom of the VHF band.
International broadcasting consists of radio and television transmissions that purposefully cross international boundaries, often with then intent of allowing expatriates to remain in touch with their countries of origin as well as educate, inform, and influence residents of foreign countries. Content can range from overt propaganda and counterpropaganda to cultural content to news reports that reflect the point of view and concerns of the originating country or that seek to provide alternative information to that otherwise available as well as promote tourism and trade. In the first half of the twentieth century, international broadcasting was used by colonial empires as a means of connecting colonies with the metropole. When operated by governments or entities close to a government, international broadcasting can be a form of soft power. Less frequently, international broadcasting has been undertaken for commercial purposes by private broadcasters.
In radio, longwave, long wave or long-wave, and commonly abbreviated LW, refers to parts of the radio spectrum with wavelengths longer than what was originally called the medium-wave broadcasting band. The term is historic, dating from the early 20th century, when the radio spectrum was considered to consist of longwave (LW), medium-wave (MW), and short-wave (SW) radio bands. Most modern radio systems and devices use wavelengths which would then have been considered 'ultra-short'.
BPM is the call sign of the official short-wave time signal service of the People's Republic of China, operated by the Chinese Academy of Sciences, broadcasting from CAS's National Time Service Center in Pucheng County, Shaanxi at 34°56′55.96″N109°32′34.93″E, roughly 70 km northeast of Lintong, along with NTSC's long-wave time signal BPL on 100 kHz.
Deutsche Welle, commonly shortened to DW, is a German public, state-owned international broadcaster funded by the German federal tax budget. The service is available in 32 languages. DW's satellite television service consists of channels in German, English, Spanish, Hindi, Persian, and Arabic. The work of DW is regulated by the Deutsche Welle Act, stating that content is intended to be independent of government influence. DW is a member of the European Broadcasting Union (EBU).
Radio Canada International (RCI) is the international broadcasting service of the Canadian Broadcasting Corporation (CBC). Prior to 1970, RCI was known as the CBC International Service. The broadcasting service was also previously referred to as the Voice of Canada, broadcasting on shortwave from powerful transmitters in Sackville, New Brunswick. "In its heyday", said Radio World magazine, "Radio Canada International was one of the world's most listened-to international shortwave broadcasters". However, as the result of an 80 percent budget cut, shortwave services were terminated in June 2012, and RCI became accessible exclusively via the Internet. It also reduced its services to five languages and ended production of its own news service.
Shortwave listening, or SWLing, is the hobby of listening to shortwave radio broadcasts located on frequencies between 1700 kHz and 30 MHz (30 000 kHz). Listeners range from casual users seeking international news and entertainment programming, to hobbyists immersed in the technical aspects of long-distance radio reception and sending and collecting official confirmations that document their reception of remote broadcasts (DXing). In some developing countries, shortwave listening enables remote communities to obtain regional programming traditionally provided by local medium wave AM broadcasters. In 2002, the number of households that were capable of shortwave listening was estimated to be in the hundreds of millions.
The Skelton Transmitting Station is a radio transmitter site at grid reference NY433376 near Skelton, Cumbria, England, about 5 miles (8 km) north-west of Penrith, run by Babcock International and owned by the Ministry of Defence. Since the Belmont Mast in Lincolnshire was shortened in 2010, the mast at Skelton has been the tallest structure in the United Kingdom.
Vatican Radio is the official broadcasting service of Vatican City.
Shortwave broadcasting in the United States allows private ownership of commercial and non-commercial shortwave stations that are not relays of existing AM/MW or FM radio stations, as are common in Africa, Europe, Asia, Oceania except Australia and Latin America. In addition to private broadcasters, the United States also has government broadcasters and relay stations for international public broadcasters. Most privately owned shortwave stations have been religious broadcasters, either wholly owned and programmed by Roman Catholic and evangelical Protestant charities or offering brokered programming consisting primarily of religious broadcasters. To better reach other continents of the world, several stations are located in far-flung US territories. Shortwave stations in the US are not permitted to operate exclusively for a domestic audience; they are subject to antenna and power requirements to reach an international audience.
The World Radio TV Handbook, also known as WRTH, is a comprehensive directory of global broadcasting. It contains most radio stations with FM or AM transmitters as well as TV stations, published yearly. The focus is on frequencies, television channels and effective transmitter powers. The listings of international broadcasting and shortwave radio contain schedules. For major broadcasters, addresses, telephone numbers and e-mail are given.
Shortwave bands are frequency allocations for use within the shortwave radio spectrum. Radio waves in these frequency ranges can be used for very long distance (transcontinental) communication because they can reflect off layers of charged particles in the ionosphere and return to Earth beyond the horizon, a mechanism called skywave or “skip” propagation. They are allocated by the ITU for radio services such as maritime communications, international shortwave broadcasting and worldwide amateur radio. The bands are conventionally named by their wavelength in metres, for example the ‘20 meter band’. Radio propagation and possible communication distances vary depending on the time of day, the season and the level of solar activity.
HCJB, "The Voice of the Andes", was the first radio station with daily programming in Ecuador and the first Christian missionary radio station in the world. The station was founded in 1931 by Clarence W. Jones, Reuben Larson, and D. Stuart Clark. HCJB now focuses on Ecuador with unified programming on FM at 89.3 MHz in Pichincha, at 92.5 MHz in Manabí, at 96.1 MHz in Tungurahua and Cotopaxi, at 98.3 MHz in Esmeraldas and with separate programming on AM at 690 kHz. Broadcasts in Spanish and indigenous languages on 6.05 MHz (1 kW), continue on an intermittent basis with a new solid state transmitter which in 2017 replaced an older (5 kW) transmitter. These broadcasts were not listed on the HCJB English website as of February 2016.
Radio Romania International is a Romanian radio station owned by the Romanian public radio broadcaster Societatea Română de Radiodifuziune that broadcasts abroad. It was created in 1927 and was known as Radio Bucharest before 1989.
The British DX Club is an association of radio hobbyists and enthusiasts, based in the United Kingdom. It caters for DXers and others with an interest in listening to the short wave, medium wave (AM), long wave and FM radio bands, and studying current and historical topics relating to radio broadcasting.
Curtain arrays are a class of large multielement directional radio transmitting wire antennas, used in the short-wave radio bands. They constitute a type of reflective array antenna, consisting of multiple wire dipole antennas, suspended in a vertical plane, often positioned in front of a "curtain" reflector made of a flat vertical screen of many long parallel wires. These are suspended by support wires strung between pairs of tall steel towers, reaching heights of up to 90 m high. Primarily employed for long-distance skywave transmission, they emit a beam of radio waves at a shallow angle into the sky just above the horizon, which is then reflected by the ionosphere back to Earth beyond the horizon. Curtain arrays are extensively used by international short-wave radio stations for broadcasting to large areas at transcontinental distances.
The radio programming in Guyana caters to a diverse ethnic demographic.
