Carrier Current
Carrier current transmission, originally called wired wireless, employs guided low-power Radio frequency, radio-frequency signals, which are transmitted along electrical conductors. The transmissions are picked up by receivers that are either connected to the conductors, or a short distance from them. Carrier current transmission is used to send audio and telemetry to selected locations, and also for low-power broadcasting that covers a small geographical area, such as a college campus. The most common form of carrier current uses longwave or medium wave Amplitude modulation, AM radio signals that are sent through existing electrical wiring, although other conductors can be used, such as telephone lines. Technology Carrier current generally uses low-power transmissions. In cases where the signals are being carried over electrical wires, special preparations must be made for distant transmissions, as the signals cannot pass through standard utility transformers. Signals can bridge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Freeform (radio Format)
Free-form, or free-form radio, is a radio station programming format in which the disc jockey is given wide or total control over what music to play, regardless of music genre or commercial interests. Freeform radio stands in contrast to most commercial radio stations, in which DJs have little or no influence over programming structure or playlists. In the United States, freeform DJs are still bound by Federal Communications Commission regulations. History in the United States Many shows claim to be the first free-form radio program, but the earliest on record is "Nightsounds" on KPFA-FM in Berkeley, California, D.J.'d by John Leonard. Probably the best-remembered in the Midwest is Beaker Street, which ran for almost 10 years on KAAY "The Mighty 1090" in Little Rock, Arkansas, beginning in 1966, making it also probably the best-known such show on an AM station; its signal reached from Canada to Mexico and Cuba, blanketing the Midwest and Midsouth of the U.S. WFMU is curren ...

Radio Stations Established In 1958
Radio is the technology of communicating using radio waves. Radio waves are electromagnetic waves of frequency between 3 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves. They can be received by other antennas connected to a radio receiver; this is the fundamental principle of radio communication. In addition to communication, radio is used for 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 (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like air ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soca Music
Soca music, or the "soul of calypso", is a genre of music that originated in Trinidad and Tobago in the 1970s. It is considered an offshoot of Calypso music, calypso, with influences from Afro–Trinidadians and Tobagonians, Afro-Trinidadian and Indo–Trinidadians and Tobagonians, Indo-Trinidadian rhythms. It was created by Ras Shorty I (or Lord Shorty) in an effort to revive traditional calypso, the popularity of which had been declining amongst younger generations in Trinidad due to the rise in popularity of reggae from Jamaica and Soul music, soul and funk from the United States. From the 1980s onward, soca has developed into a range of new styles. Etymology "Soca" is a Blend word, portmanteau of the words "soul" and "calypso". The genre was defined by Lord Shorty as the "Soul of Calypso." The word was originally spelled s-o-k-a-h by Lord Shorty. In a 1979 interview with ''Carnival Magazine,'' Lord Shorty stated that he "came up with the name soca. I invented soca. And I ...

Caribbean Music
Caribbean music genres are very diverse. They are each synthesis of African, European, Asian and Indigenous influences, largely created by descendants of African enslaved people (see Afro-Caribbean music), along with contributions from other communities (such as Indo-Caribbean music). Some of the styles to gain wide popularity outside the Caribbean include, bachata, merengue, palo, mambo, baithak gana, bouyon, cadence-lypso, calypso, soca, chutney, chutney-soca, compas, dancehall, jing ping, parang, pichakaree, punta, ragga, reggae, dembow, reggaeton, salsa, and zouk. Caribbean music is also related to Central American and South American music. The history of Caribbean music originates from the history of the Caribbean itself. That history is one of the native land invaded by outsiders; violence, slavery, and even genocide factor in. Following Christopher Columbus' landing in 1492, Spain laid claim to the entire Caribbean. This claim was met with dissatis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reggae
Reggae () is a music genre that originated in Jamaica during the late 1960s. The term also denotes the modern popular music of Jamaica and its Jamaican diaspora, diaspora. A 1968 single by Toots and the Maytals, "Do the Reggay", was the first popular song to use the word ''reggae'', effectively naming the genre and introducing it to a global audience. Reggae is rooted in traditional Jamaican Kumina, Pukkumina, Revival Zion, Nyabinghi, and burru drumming. Jamaican reggae music evolved out of the earlier genres mento, ska and rocksteady. Reggae usually relates news, social gossip, and political commentary. It is recognizable from the counterpoint between the bass and drum downbeat and the offbeat rhythm section. The immediate origins of reggae were in ska and rocksteady; from the latter, reggae took over the use of the bass as a percussion instrument. Stylistically, reggae incorporates some of the musical elements of rhythm and blues, jazz, mento (a celebratory, rural folk form ...

College Radio
Campus radio (also known as college radio, university radio or student radio) is a type of radio station that is run by the students of a college, university or other educational institution. Programming may be exclusively created or produced by students, or may include program contributions from the local community in which the radio station is based. Sometimes campus radio stations are operated for the purpose of training professional radio personnel, sometimes with the aim of broadcasting educational programming, while other radio stations exist to provide alternative to commercial broadcasting or government broadcasters. Campus radio stations are generally licensed and regulated by national governments, and have very different characteristics from one country to the next. One commonality between many radio stations regardless of their physical location is a willingness—or, in some countries, even a licensing requirement—to broadcast musical selections that are not categ ...

Transmitter
In electronics and telecommunications, a radio transmitter or just transmitter (often abbreviated as XMTR or TX in technical documents) is an electronic device which produces radio waves with an antenna (radio), antenna with the purpose of signal transmission to a radio receiver. The transmitter itself generates a radio frequency alternating current, which is applied to the Antenna (radio), antenna. When excited by this alternating current, the antenna Electromagnetic radiation, radiates radio waves. Transmitters are necessary component parts of all electronic devices that communicate by radio communication, radio, such as radio broadcasting, radio (audio) and television broadcasting stations, cell phones, walkie-talkies, Wireless LAN, wireless computer networks, Bluetooth enabled devices, garage door openers, two-way radios in aircraft, ships, spacecraft, radar sets and navigational beacons. The term ''transmitter'' is usually limited to equipment that generates radio waves fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
