Radio Jamaica
Radio Jamaica, also known as RJR 94 FM, and formerly Real Jamaican Radio, is a broadcast company in Jamaica with headquarters in Kingston. History On 9 July 1950, a commercial license to operate as a subsidiary of the British Rediffusion Group was issued to the Radio Jamaica and Rediffusion Network. Initially only four medium-wave, signal transmission sites broadcast throughout the island. In 1951 wire radio service was established from a central broadcasting station. Transmissions were sent to rediffusion speaker boxes for which subscribers paid three-pence per day. To increase the listener base RJR distributed around 200 rediffusion speakers to police stations, retail stores and schools. In 1953, Jamaica became the first of the British colonies in the Caribbean to offer FM broadcasting when RJR began using the technology. By 1954, there were over 57,000 rediffusion boxes distributed throughout the country. In 1959 Jamaica Broadcasting Corporation was founded as a public bro ...

Jamaica
Jamaica (; ) is an island country situated in the Caribbean Sea. Spanning in area, it is the third-largest island of the Greater Antilles and the Caribbean (after Cuba and Hispaniola). Jamaica lies about south of Cuba, and west of Hispaniola (the island containing the countries of Haiti and the Dominican Republic); the British Overseas Territory of the Cayman Islands lies some to the north-west. Originally inhabited by the indigenous Taíno peoples, the island came under Spanish rule following the arrival of Christopher Columbus in 1494. Many of the indigenous people either were killed or died of diseases, after which the Spanish brought large numbers of African slaves to Jamaica as labourers. The island remained a possession of Spain until 1655, when England (later Great Britain) conquered it, renaming it ''Jamaica''. Under British colonial rule Jamaica became a leading sugar exporter, with a plantation economy dependent on the African slaves and later their des ...

Kingston, Jamaica
Kingston is the capital and largest city of Jamaica, located on the southeastern coast of the island. It faces a natural harbour protected by the Palisadoes, a long sand spit which connects the town of Port Royal and the Norman Manley International Airport to the rest of the island. In the Americas, Kingston is the largest predominantly English-speaking city in the Caribbean. The local government bodies of the parishes of Kingston and Saint Andrew were amalgamated by the Kingston and St. Andrew Corporation Act of 1923, to form the Kingston and St. Andrew Corporation (KSAC). Greater Kingston, or the "Corporate Area" refers to those areas under the KSAC; however, it does not solely refer to Kingston Parish, which only consists of the old downtown and Port Royal. Kingston Parish had a population of 89,057, and St. Andrew Parish had a population of 573,369 in 2011 Kingston is only bordered by Saint Andrew to the east, west and north.

FM Broadcasting
FM broadcasting is a method of radio broadcasting using frequency modulation (FM). Invented in 1933 by American engineer Edwin Armstrong, wide-band FM is used worldwide to provide high fidelity sound over broadcast radio. FM broadcasting is capable of higher fidelity—that is, more accurate reproduction of the original program sound—than other broadcasting technologies, such as AM broadcasting. It is also less susceptible to common forms of interference, reducing static and popping sounds often heard on AM. Therefore, FM is used for most broadcasts of music or general audio (in the audio spectrum). FM radio stations use the very high frequency range of radio frequencies. Broadcast bands Throughout the world, the FM broadcast band falls within the VHF part of the radio spectrum. Usually 87.5 to 108.0 MHz is used, or some portion thereof, with few exceptions: * In the former Soviet republics, and some former Eastern Bloc countries, the older 65.8–74 MHz band ...

Transistor
upright=1.4, gate (G), body (B), source (S) and drain (D) terminals. The gate is separated from the body by an insulating layer (pink). A transistor is a semiconductor device used to Electronic amplifier, amplify or electronic switch, switch electrical signals and electrical power, power. The transistor is one of the basic building blocks of modern electronics. It is composed of semiconductor material, usually with at least three terminals for connection to an electronic circuit. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Some transistors are packaged individually, but many more are found embedded in integrated circuits. Austro-Hungarian physicist Julius Edgar Lilienfeld proposed the concept of a field-effect transistor in 1926, but it was not possible to actually cons ...

Transmitter
In electronics and telecommunications, a radio transmitter or just transmitter is an electronic device which produces radio waves with an antenna. The transmitter itself generates a radio frequency alternating current, which is applied to the antenna. When excited by this alternating current, the antenna radiates radio waves. Transmitters are necessary component parts of all electronic devices that communicate by radio, such as radio and television broadcasting stations, cell phones, walkie-talkies, 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 for communication purposes; or radiolocation, such as radar and navigational transmitters. Generators of radio waves for heating or industrial purposes, such as microwave ovens or diathermy equipment, are not usually called transmitter ...
