Radio broadcasting - Wikipedia. Long wave radio broadcasting station, Motala, Sweden. Radio broadcasting is a unidirectional wireless transmission over 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. Audio broadcasting also can be done via cable radio, local wire television networks, satellite radio, and internet radio via streaming media on the Internet.

The signal types can be either analog audio or digital audio. History. For audio broadcasts to be possible electronic detection and amplification devices had to be incorporated. The thermionic valve was invented in 1. English physicist John Ambrose Fleming. He developed a device he called an . The heated filament, or cathode, was capable of thermionic emission of electrons that would flow to the plate (or anode) when it was at a higher voltage.

Electrons, however, could not pass in the reverse direction because the plate was not heated and thus not capable of thermionic emission of electrons. Later known as the Fleming valve, it could be used as a rectifier of alternating current and as a radio wave detector. However, what was still required was an amplifier. The triode (mercury- vapor filled with a control grid) was patented on March 4, 1. Austrian Robert von Lieben. It wasn't put to practical use until 1. Charles Herrold started broadcasting in California in 1.
In 1. 91. 6, Frank Conrad, an electrical engineer employed at the Westinghouse Electric Corporation, began broadcasting from his Wilkinsburg, Pennsylvania garage with the call letters 8. XK. Later, the station was moved to the top of the Westinghouse factory building in East Pittsburgh, Pennsylvania.
Westinghouse relaunched the station as KDKA on November 2, 1. America. The first licensed broadcast in the United States came from KDKA itself: the results of the Harding/Cox Presidential Election.

She was the first artist of international renown to participate in direct radio broadcasts. The 2. MT station began to broadcast regular entertainment in 1. The BBC was amalgamated in 1. Royal Charter in 1. The station got its license on November 1.
The delay was due to the lack of official Argentine licensing procedures before that date. This station continued regular broadcasting of entertainment and cultural fare for several decades. Curry College in Milton, Massachusetts introduced one of the first broadcasting majors in 1. WLOE in Boston to have students broadcast programs. These include AM and FM stations. There are several subtypes, namely commercial broadcasting, non- commercial educational (NCE) public broadcasting and non- profit varieties as well as community radio, student- run campus radio stations and hospital radio stations can be found throughout the world.
Many stations broadcast on shortwave bands using AM technology that can be received over thousands of miles (especially at night). For example, the BBC, VOA, VOR, and Deutsche Welle have transmitted via shortwave to Africa and Asia. These broadcasts are very sensitive to atmospheric conditions and solar activity.
Nielsen Audio, formerly known as Arbitron, the United States- based company that reports on radio audiences, defines a . Shortwave is used largely for national broadcasters, international propaganda, or religious broadcasting organizations.
AM refers to amplitude modulation, a mode of broadcasting radio waves by varying the amplitude of the carrier signal in response to the amplitude of the signal to be transmitted. The medium- wave band is used worldwide for AM broadcasting. Europe also uses the long wave band. In response to the growing popularity of FM stereo radio stations in the late 1. North American stations began broadcasting in AM stereo, though this never gained popularity, and very few receivers were ever sold. One of the advantages of AM is that its signal can be detected (turned into sound) with simple equipment. If a signal is strong enough, not even a power source is needed; building an unpowered crystal radio receiver was a common childhood project in the early decades of AM broadcasting.
AM broadcasts occur on North American airwaves in the medium wave frequency range of 5. Hz (known as the . The band was expanded in the 1. Hz. Channels are spaced every 1.
Hz in the Americas, and generally every 9 k. Hz everywhere else. The signal is subject to interference from electrical storms (lightning) and other electromagnetic interference (EMI). AM transmissions cannot be ionospherically propagated during the day due to strong absorption in the D- layer of the ionosphere. In a crowded channel environment this means that the power of regional channels which share a frequency must be reduced at night or directionally beamed in order to avoid interference, which reduces the potential nighttime audience.
Some stations have frequencies unshared with other stations in North America; these are called clear- channel stations. Many of them can be heard across much of the country at night. During the night, absorption largely disappears and permits signals to travel to much more distant locations via ionospheric reflections. However, fading of the signal can be severe at night. AM radio transmitters can transmit audio frequencies up to 1.
Hz (now limited to 1. Hz in the US due to FCC rules designed to reduce interference), but most receivers are only capable of reproducing frequencies up to 5 k. Hz or less. At the time that AM broadcasting began in the 1. The fidelity of sound equipment subsequently improved considerably, but the receivers did not.
Reducing the bandwidth of the receivers reduces the cost of manufacturing and makes them less prone to interference. AM stations are never assigned adjacent channels in the same service area. This prevents the sideband power generated by two stations from interfering with each other. After several years, the tuner was discontinued. Bob Carver had left the company and the Carver Corporation later cut the number of models produced before discontinuing production completely. Russia, like the former Soviet Union, uses 6. MHz frequencies in addition to the world standard.
Japan uses the 7. MHz frequency band. Edwin Howard Armstrong invented FM radio to overcome the problem of radio- frequency interference (RFI), which plagued AM radio reception. At the same time, greater fidelity was made possible by spacing stations further apart in the radio frequency spectrum. Instead of 1. 0 k.
Hz apart, as on the AM band in the US, FM channels are 2. Hz (0. 2 MHz) apart. In other countries greater spacing is sometimes mandatory, such as in New Zealand, which uses 7. Hz spacing (previously 8. Hz). The improved fidelity made available was far in advance of the audio equipment of the 1.
FM. Bandwidth of 2. Hz is not needed to accommodate an audio signal . The 2. 00 k. Hz bandwidth allowed room for . The larger bandwidth allows for broadcasting a 1. Hz bandwidth audio signal plus a 3. Hz stereo . Additional unused capacity is used by some broadcasters to transmit utility functions such as background music for public areas, GPS auxiliary signals, or financial market data.
The AM radio problem of interference at night was addressed in a different way. At the time FM was set up, the available frequencies were far higher in the spectrum than those used for AM radio - by a factor of approximately 1.
Using these frequencies meant that even at far higher power, the range of a given FM signal was much shorter; thus its market was more local than for AM radio. The reception range at night is the same as in the daytime. All FM broadcast transmissions are line- of- sight, and ionospheric bounce is not viable.
The much larger bandwidths, compared to AM and SSB, are more susceptible to phase dispersion. Propagation speeds (celerities) are fastest in the ionosphere at the lowest sideband frequency. The celerity difference between the highest and lowest sidebands is quite apparent to the listener. Such distortion occurs up to frequencies of approximately 5. MHz. Higher frequencies do not reflect from the ionosphere, nor from storm clouds. Moon reflections have been used in some experiments, but require impractical power levels.
The original FM radio service in the U. S. It required purchase of a special receiver. The frequencies used, 4. MHz, were not those used today. The change to the current frequencies, 8.
MHz, began after the end of World War II, and was to some extent imposed by AM broadcasters as an attempt to cripple what was by now realized to be a potentially serious threat. FM radio on the new band had to begin from the ground floor.
As a commercial venture it remained a little- used audio enthusiasts' medium until the 1. The more prosperous AM stations, or their owners, acquired FM licenses and often broadcast the same programming on the FM station as on the AM station (. The FCC limited this practice in the 1. By the 1. 98. 0s, since almost all new radios included both AM and FM tuners, FM became the dominant medium, especially in cities. Because of its greater range, AM remained more common in rural environments. Pirate radio. It is most commonly used to describe illegal broadcasting for entertainment or political purposes. Sometimes it is used for illegal two- way radio operation.
Its history can be traced back to the unlicensed nature of the transmission, but historically there has been occasional use of sea vessels.
