- International broadcasting
International broadcasting is
broadcastingthat is deliberately aimed at a foreign, rather than a domestic, audience. It usually is broadcast by means of longwave, mediumwave, or shortwaveradio, but in recent years has also used direct satellitebroadcasting and the Internetas means of reaching audiences.
Although radio and television programs do travel outside national borders, in many cases reception by foreigners is accidental. However, for purposes of
propaganda, transmitting religious beliefs, keeping in touch with colonies or expatriates, education, improving trade, increasing national prestige, or promoting tourism and goodwill, broadcasting services have operated external services since the 1920s.
Reasons for international broadcasting
Broadcasters in one country have several reasons to reach out to an audience in other countries. The examples given below are not meant to be exhaustive, but are illustrative.
One clear reason is for ideological, or
propagandareasons. Many government-owned stations portray their nation in a positive, non-threatening way. This could be to encourage business investment and/or tourism to the nation. Another reason is to combat a negative image produced by other nations or internal dissidents, or insurgents. Radio RSA, the broadcasting arm of the apartheid South African government, is an example of this. A third reason is to promote the ideology of the broadcaster. For example, a program on Radio Moscow from the 1960s to the 1980s was "What is Communism?"
Other reasons include broadcasting news which might be censored, or at least of little interest, in a nation. The
BBC World Serviceand the Voice of Americahave emphasized news broadcasts. In addition to these services, during the Soviet domination of Eastern Europe, Radio Free Europeserved as a surrogate domestic service for nations "behind the Iron Curtain."
In the case of emergencies, a nation may broadcast special programs overseas to inform listeners what is occurring. During Iraqi missile strikes on Israel during the 1991 Gulf War,
Kol Israelrelayed its domestic service on its shortwave service.
Besides ideological reasons, many stations are run by religious broadcasters and are used to provide religious education, religious music, or worship service programs. For example,
Vatican Radio, established in 1927, broadcasts such programs. Another station, such as HCJB International or Trans World Radiowill carry brokered programming from evangelists. In the case of the Broadcasting Service of the Kingdom of Saudi Arabia, both governmental and religious programming is provided.
Stations also broadcast to international audiences for cultural reasons. Often a station has an official mandate to keep expatriates in touch with the home country. Many broadcasters often relay their national domestic service on shortwave for that reason. Other reasons include teaching a foreign language, such as
Radio Exterior de España's Spanish class, "Un idioma sin fronteras", or the Voice of America's broadcasts in Special English. In the case of major broadcasters such as the BBC World Serviceor Radio Australia, there is also an educational outreach.
History of international broadcasting
International broadcasting, in a limited extent, began during
World War I, when Central Powers and Allied stations broadcast press communiqués using Morse code. For example, the station in Nauen, Germanybecame a fully commercial telegraph station in 1911, with a 260 m high antenna and a spark-gap transmitter running 100 kW of power. During World War I, with the severing of Germany's undersea cables, Nauen was the sole means of long-distance communication of Germany. The US Navy Radio Service radio station in New Brunswick, Canada, transmitted the Fourteen Points by wireless to Nauen in 1917. [Wood 2000: 56] . In turn, Nauen station broadcast the news of the abdication of Kaiser Wilhelm IIon November 10, 1918. [U.S. Government Printing Office. "International Law Documents: Neutrality, Conduct and Conclusion of Hostilities". 1919, p. 55]
Following experiments in the shortwave frequencies in 1925 from Eindhoven, in the Netherlands, radio station PCJ began broadcasting to the Indonesia on March 11, 1927. ["History of Radio Netherlands". http://www.bureauafrique.nl/autresdepartements/africa/Radionetherlandsturns60/aboutrnw_history]
BBCfollowed this with the BBC Empire Serviceon December 19, 1932, with transmissions aimed towards Australia and New Zealand. [BBC World Service. "World Service timeline". http://www.bbc.co.uk/worldservice/history/timeline.shtml]
Other notable early international broadcasters included Vatican Radio (
February 12, 1931), Radio Moscow, the official service of the Soviet Unionwhich began broadcasting on long-wave in 1923 (this has since been renamed the Voice of Russia, following the collapse of the Soviet Union).
Clarence W. Jones started transmitting on Christmas Day, 1931 from Missionary Radio Station
HCJBin Quito, Ecuador.
Shortwave broadcasting from
Nauento the USA, Central and South America, and the Far East began in 1926. A second station, Zeesen, was added later. [Wood 2000: 49] In January 1932, the German Reichpost assumed control of the Nauen station and added to its shortwave and longwave capacity. [Wood 2000:57]
Broadcasting in South Asia was launched in 1925 in
Ceylon- Radio Ceylon, now the Sri Lanka Broadcasting Corporationis the oldest in the region.
Shortwave programming was a low priority in the
Weimar Republic. Once Adolf Hitlerassumed power in 1933, shortwave, under the " Rundfunk Ausland" (Foreign Radio Section), was regarded as a vital element of Nazi propaganda. German shortwave hours were increased from two hours a day to 18 per day, and eventually twelve languages were broadcast on a 24-hour basis, including English. A 100 kilowatttransmitter and antenna complex was built at Zeesen, near Berlin. Specialty target programming to the United States began in 1933, to South Africa, South America, and East Asia in 1934, and South Asia and Central America in 1938.
In the 1930s, international broadcasting was a key means of promoting
Nazi Germanyforeign policy. German propagandawas organized under Joseph Goebbels, and played a key role in the German occupation of Austria and the Munich Crisis of 1938.
Mediumwave transmitters on the periphery of the Third Reich provided specialty programs to listeners in neighboring countries. Nevertheless, the Germans always had a problem staffing their foreign services with announcers who were both technically competent and loyal to Nazi ideas. [Shirer, William. "Berlin Diary"]
In 1936, the
International Radio Unionrecognized Vatican Radio as a "special case" and authorized its broadcasting without any geographical limits. On December 25, 1937, a Telefunken 25-kW transmitter and two directional antennas were added. Vatican Radio broadcast over 10 frequencies. [Levillain 2002: 1600] .
Spanish Civil War, the Nationalist forces received a powerful Telefunken transmitter as a gift of Nazi Germany to aid their propaganda efforts, and until 1943 Radio Nacional de Españacollaborated with the Axis powers to retransmit in Spanish news from the official radio stations of Germany and Italy.
World War II
During the Second World War, Russian, German, British, and Italian international broadcasting services expanded. In 1942, the United States initiated its international broadcasting service, the
Voice of America. In the Pacific theater, General Douglas MacArthurused shortwave radio to keep in touch with the citizens of the Japanese-occupied Philippine Islands.
Several announcers who became well-known in their countries included
British Union of Fascistsmember William Joyce, who was one of the two "Lord Haw-Haw"s; Frenchmen Paul Ferdonnetand Andre Olbrecht, called "the traitors of [Radio] Stuttgart"; and Americans Frederick William Kaltenbach, "Lord Hee-Haw", and Mildred Gillars, one of the two announcers called "Axis Sally". Listeners to German programs often tuned in for curiosity's sake--at one time, German radio had half a million listeners in the U.S.--but most of them soon lost interest. Japan had "Tokyo Rose," who broadcast Japanese propaganda in English, along with American music to help insure listeners.
For details of German propaganda themes, see
World War II, Vatican Radio's news broadcasts were banned in Germany. During the war, the radio service operated in four languages. [Levillain 2002: 1600] .
The British launched
Radio SEACfrom Colombo, Ceylon(Sri Lanka) during World War II. The station broadcast radio programs to the allied armed forces across the region from their headquarters in Ceylon.
Following the war and German partition, each Germany developed its own international broadcasting station:
Deutsche Welle, using studios in Cologne, West Germany, and Radio Berlin International(RBI) in East Germany. RBI's broadcasts ceased shortly before the reunification of Germany on October 3, 1990, and Deutsche Welle took over its transmitters and frequencies.
The Cold War Era (1945-1991): modern practices, modern technology
The Cold War led to increased international broadcasting, as Communist and non-Communist states attempted to influence each other's domestic population. Some of the most prominent Western broadcasters were the Voice of America, the
BBC World Service, and the (covertly) CIA-backed Radio Free Europe/ Radio Liberty. The Soviet Union's most prominent service was Radio Moscow(now the Voice of Russia) and China used Radio Peking(then Radio Beijing, now China Radio International). In addition to the U.S.-Soviet cold war, the Chinese-Russian border dispute led to an increase of the numbers of transmitters aimed at the two nations, and the development of new techniques such as playing tapes backwards for reel-to-reel recorders.
West Germany resumed regular shortwave broadcasts using Deutsche Welle on May 3, 1953. Its Julich transmitter site began operation in 1956, with eleven 100-kW Telefunken transmitters. The Wectachtal site was authorized in 1962 and began with four 500-kW transmitters. By 1989, there were 15 transmitters, four of which relayed the Voice of America. [Wood 2000: 51] . Meanwhile in East Germany, the Nauen site began transmitting Radio DDR, later Radio Berlin International, on October 15, 1959. [Wood 2000: 58]
In addition to the superpower states, international broadcast services grew in Europe and the Middle East. Under the presidency of Gamal Nasser, Egyptian transmitters covered the Arab world; Israel's service,
Kol Yisrael, served both to present the Israeli point of view to the world and to serve the Jewish diaspora, particularly behind the " Iron Curtain".
Radio RSA, as part of the South African Broadcasting Corporation, was established in 1966 to promote the image of South Africa internationally and reduce criticism of apartheid. [Horwitz 2001: 287] . It continued in 1992, when the post-apartheid government renamed it
Ironically, the isolationist
Albaniaunder Enver Hoxha, virtually a hermit kingdom, became one of the most prolific international broadcasters during the latter decades of the Cold War, with Radio Tiranaone of the top five broadcasters in terms of hours of programming produced (Although Radio Tirana's programming was almost universally regarded as insufferably dull).
Post Cold War to today
At the end of the Cold War, many international broadcasters cut back on hours and foreign languages broadcast, or reemphasized other language services. For example, in 1984, Radio Canada International broadcast in English, French, German, Spanish, Czech/Slovak, Hungarian, Polish, Russian, and Ukrainian. In 2005, Canada broadcast in English, Chinese, Arabic, Russian, and Spanish There is a trend towards more TV (e.g. BBC World, NHK World, CCTV-9), and news websites. Some services, such as Swiss Radio International, left shortwave altogether and exist in Internet form. In addition, new standards, such as
Digital Radio Mondiale, are being introduced, as well as sending programs over the Web to be played back later, as " podcasts."
Daily developments are followed in Radio Netherlands' Media Network
Means to reach an audience
Because of this many broadcasters are discovering they can reach a wider audience through other methods (particularly the internet and satellite television) and are cutting back on (or even entirely dropping) shortwave.
An international broadcaster has several options for reaching a foreign audience:
* If the foreign audience is near the broadcaster, high-power longwave and mediumwave stations can provide reliable coverage.
* If the foreign audience is more than 1,000 kilometers away from the broadcaster, shortwave radio is reliable, but subject to interruption by adverse solar/geomagnetic conditions.
* An international broadcaster may use a local mediumwave or FM radio or television relay station in the target country or countries.
* An international broadcaster may use a local shortwave broadcaster as a relay station.
* Neighboring states, such as
Israeland Jordan, may broadcast television programs to each other's viewing public.
An international broadcaster such as the BBC, Radio France International or Germany's Deutsche Welle, may use all the above methods. Several international broadcasters, such as
Swiss Radio International, have abandoned shortwave broadcasting altogether, relying on Internet transmissions only. Others, such as the BBC World Service, have abandoned shortwave transmissions to North America, relying on local relays, the Internet, and satellite transmissions
Mediumwave and longwave broadcasts
Most radio receivers in the world receive the
mediumwaveband (530 kHz to 1710 kHz), which at night is capable of reliable reception from 150 to 2,500 km distance from a transmitter. Mediumwave is used heavily the world over for international broadcasting on a formal and informal basis.
In addition, many receivers used in Europe and Russia can receive the
longwavebroadcast band (150 to 280 kHz), which provides reliable long-distance communications over continental distances.
Yet other receivers are capable of receiving
shortwavetransmissions (2,000 to 30,000 kHz or 2 to 30 MHz). Depending on time of day, season of year, solar weather and Earth's geomagnetic field, a signal might reach around the world.
In previous decades shortwave (and sometimes high-powered mediumwave) transmission was regarded as the main (and often the "only") way in which broadcasters could reach an international audience. In recent years the proliferation of technologies such as satellite broadcasting, the Internet, and rebroadcasts of programming on AM and FM within target nations has meant that this is no longer necessarily the case.
Transmitter output power has increased since 1920. Higher transmitter powers do guarantee better reception in the target area. Higher transmitter power in most cases counteracts the lesser effects of jamming.
* 1950s : 100 kW
* 1960s : 200 kW, early 1960s (2 x 100 kW 'twinned')
* 1970s : 300 kW, but many 250 kW transmitters sold
* 1980s : 500 kW sometimes transmitters were "doubled up" to produce 1000 Kw output
* 1980s-Present: 600 kW single, 1200 kW from twinned transmitters.
International stations generally use special directional antennas to aim the signal toward the intended audience and increase the effective power in that direction. Use of such antennas for international broadcasting began in the mid 1930s and became prominent by the 1950s. By using these antennas a station may achieve tens of millions of
Wattsof radio power today.
An international broadcaster may have the technical means of reaching a foreign audience, but unless the foreign audience has a reason to listen, the effectiveness of the broadcaster is in question.
One of the most common foreign audiences consists of expatriates, who cannot listen to radio or watch television programs from home. Another common audience is radio hobbyists, who attempt to listen as many countries as possible and obtain verification cards or letters ("QSLs"). A third audience consists of
journalists, governmentofficials, and key businesspersons, who exert a disproportionate influence on a state's foreign or economic policy.
A fourth, but less publicized audience, consists of intelligence officers and agents who monitor broadcasts for both
open-source intelligenceclues to the broadcasting state's policies and for hidden messages to foreign agents operating in the receiving country. The BBC started its monitoring service in Caversham, Reading in 1936 (now BBC Monitoring). In the United States, the DNI Open Source Center(formerly the Central Intelligence Agency's Foreign Broadcast Information Service) provides the same service. Copies of OSC/FBIS reports can be found in many U.S. libraries that serve as government depositories. In addition, a number of hobbyists listen and report "spook" transmissions.
Without these four audiences, international broadcasters face difficulty in getting funding. In 2001, for example, the BBC World Service stopped transmitting shortwave broadcasts to North America, and other international broadcasters, such as YLE Radio Finland, stopped certain foreign-language programs.
However, international broadcasting has been successful when a country does not provide programming wanted by a wide segment of the population. In the 1960s, when there was no BBC service playing rock and roll, Radio Television Luxembourg (RTL) broadcast rock and roll, including bands such as
the Beatles, into the United Kingdom. Similar programming came from an unlicensed, or "pirate" station, Radio Caroline, which broadcast from a ship in the international waters of the North Sea.
In many cases, governments do not want their citizens listening to international broadcasters. In Nazi Germany, a major propaganda campaign, backed by law and prison sentences, attempted to discourage Germans from listening to such stations. The practice was made illegal in 1939. [Hughes and Mann 2002: 93] In addition, the German government sold a cheap, 76-
Reichsmark"People's Receiver", as well as an even cheaper 35-Reichsmark receiver, [Hughes and Mann 2002: 93] that could not pick up distant signals well. [Graef 2005: 36] .
The idea was copied by Stalin's Soviet Union, which had a nearly identical copy manufactured in the Tesla factory in Czechoslovakia. [Graef 2005: 36] In North Korea, all receivers are sold with fixed frequencies, tuned to local stations.
The most common method of preventing reception is jamming, or broadcasting a signal on the same frequencies as the international broadcaster. Germany jammed the BBC European service during the Second World War. Russian and Eastern European jammers were aimed against
Radio Free Europe, other Western broadcasters, and against Chinese broadcasters during the nadir of Sino-Soviet relations. In 2002, the Cuban government jammed the Voice of America's Radio Martiprogram and the Chinese government jammed broadcasts made by adherents of Falun Gong.
North Korea restricts most people to a single fixed frequency mediumwave receiver; those who met political requirements and whose work absolutely required familiarity with events abroad were allowed shortwave receivers. [Martin 2006: 495] Another method of reaching people with government radio programming, but not foreign programming, is the use of radio broadcasting by direct broadcasting to loudspeakers. [Goetz, Philip W. "The New Encyclopedia Brittanica", 1991 edition, ISBN 085229400X, p 315] David Jackson, director of the Voice of America, noted "The North Korean government doesn't jam us, but they try to keep people from listening through intimidation or worse. But people figure out ways to listen despite the odds. They're very resourceful." [Jackson, David. "The Future of Radio II". World Radio TV Handbook, 2007 edition. 2007, Billboard Books. ISBN 0823059979. p 38.]
Yet another method of preventing reception involves moving a domestic station to the frequency used by the international broadcaster. During the Batista government of Cuba, and during the Castro years, Cuban medium-wave stations broadcast on the frequencies of popular South Florida stations. In October 2002, Iraq changed frequencies of two stations to block the Voice of America's
Jamming can be defeated by using very powerful transmitting antennas, carefully choosing the transmitted frequency, changing transmitted frequency often, using Single Sideband, and properly aiming the receiving antenna.
