The Australian Broadcasting Corporation (ABC) is the national broadcaster of Australia. It is principally funded by direct grants from the Australian Government and is administered by a government-appointed board. The ABC is a publicly-owned body that is politically independent and fully accountable, with its charter enshrined in legislation, the Australian Broadcasting Corporation Act 1983. ABC Commercial, a profit-making division of the corporation, also helps to generate funding for content provision.
Triple J is a government-funded, national Australian radio station that began broadcasting in 1975 as a division of the Australian Broadcasting Corporation (ABC). It aims to appeal to young listeners of alternative music, and plays more Australian content than commercial networks.
Very high frequency (VHF) is the ITU designation for the range of radio frequency electromagnetic waves from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter. Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high frequency (UHF).
Effective radiated power (ERP), synonymous with equivalent radiated power, is an IEEE standardized definition of directional radio frequency (RF) power, such as that emitted by a radio transmitter. It is the total power in watts that would have to be radiated by a half-wave dipole antenna to give the same radiation intensity as the actual source antenna at a distant receiver located in the direction of the antenna's strongest beam. ERP measures the combination of the power emitted by the transmitter and the ability of the antenna to direct that power in a given direction. It is equal to the input power to the antenna multiplied by the gain of the antenna. It is used in electronics and telecommunications, particularly in broadcasting to quantify the apparent power of a broadcasting station experienced by listeners in its reception area.
It is generally recognized that the first radio transmission was made from a temporary station set up by Guglielmo Marconi in 1895 on the Isle of Wight. This followed on from pioneering work in the field by a number of people including Alessandro Volta, André-Marie Ampère, Georg Ohm and James Clerk Maxwell.
AM stereo is a term given to a series of mutually incompatible techniques for radio broadcasting stereo audio in the AM band in a manner that is compatible with standard AM receivers. There are two main classes of systems: independent sideband (ISB) systems, promoted principally by American broadcast engineer Leonard R. Kahn; and quadrature amplitude modulation (QAM) multiplexing systems.
3RRR is an Australian community radio station, based in Melbourne.
Nine Radio is an Australian media company, owned by parent company Nine Entertainment Co. and headquartered in North Sydney, New South Wales. The company operates radio stations nationally in the capital cities of Sydney, Melbourne, Brisbane and Perth, as well as regional Queensland.
A ground station, Earth station, or Earth terminal is a terrestrial radio station designed for extraplanetary telecommunication with spacecraft, or reception of radio waves from astronomical radio sources. Ground stations may be located either on the surface of the Earth, or in its atmosphere. Earth stations communicate with spacecraft by transmitting and receiving radio waves in the super high frequency (SHF) or extremely high frequency (EHF) bands. When a ground station successfully transmits radio waves to a spacecraft, it establishes a telecommunications link. A principal telecommunications device of the ground station is the parabolic antenna.
A Maritime Mobile Service Identity (MMSI) is effectively a maritime object's international maritime telephone number, a temporarily assigned UID, issued by that object's current flag state.
FM broadcasting is a method of radio broadcasting that uses frequency modulation (FM) of the radio broadcast carrier wave. Invented in 1933 by American engineer Edwin Armstrong, wide-band FM is used worldwide to transmit high-fidelity sound over broadcast radio. FM broadcasting offers higher fidelity—more accurate reproduction of the original program sound—than other broadcasting techniques, such as AM broadcasting. It is also less susceptible to common forms of interference, having less static and popping sounds than are often heard on AM. Therefore, FM is used for most broadcasts of music and general audio. FM radio stations use the very high frequency range of radio frequencies.
Radio enjoys a huge following in the United Kingdom. There are around 600 licensed radio stations in the country. For a more comprehensive list see List of radio stations in the United Kingdom.
ABC Classic, formerly ABC-FM, and then ABC Classic FM, is an Australian classical music radio station available in Australia and internationally. Its website features classical music news, features and listening guides. It is operated by the Australian Broadcasting Corporation (ABC).
An amateur radio station is a radio station designed to provide radiocommunications in the amateur radio service for an amateur radio operator. Radio amateurs build and operate several types of amateur radio stations, including fixed ground stations, mobile stations, space stations, and temporary field stations. A slang term often used for an amateur station's location is the shack, named after the small enclosures added to the upperworks of naval ships to hold early radio equipment and batteries.
The Three Angels Broadcasting Network, or 3ABN, is a Christian media television and radio network which broadcasts Seventh-day Adventist religious, music and health-oriented programming, based in West Frankfort, Illinois, United States. Although it is not formally tied to any particular church or denomination, much of its programming focuses on Seventh-day Adventist theology and Adventist doctrine.
The Goulburn Valley's 95.3 Triple M is a commercial radio station broadcasting from Shepparton, Victoria, Australia. It is currently owned by Southern Cross Austereo & broadcasts an Adult Contemporary (AC) format. It features both locally produced content & nationally syndicated content. A repeater is located at Mansfield (91.3FM). It was previously known as '3SR FM' until it was rebranded as Triple M in December 2016, alongside many other Southern Cross Austereo stations. It is a part of the Triple M network.
The Kent Music Report was a weekly record chart of Australian music singles and albums which was compiled by music historian David Kent from May 1974 through to January 1999. The chart was re-branded the Australian Music Report (AMR) in July 1987. From June 1988, the Australian Recording Industry Association, which had been using the top 50 portion of the report under licence since mid-1983, chose to produce their own listing as the ARIA Charts.
Adult contemporary music (AC) is a form of radio-played popular music, ranging from 1960s vocal and 1970s soft rock music to predominantly ballad-heavy music of the 1980s to the present day, with varying degrees of easy listening, pop, soul, R&B, quiet storm and rock influence. Adult contemporary is generally a continuation of the easy listening and soft rock style that became popular in the 1960s and 1970s with some adjustments that reflect the evolution of pop/rock music.
RSN Racing & Sport is an Australian radio station in Australia. Owned and operated by thoroughbred, harness and greyhound racing bodies of Victoria, it broadcasts a sports radio format to Melbourne, and to much of Victoria through various repeater stations. First broadcast as 3UZ on 8 March 1925, it was in 1986 sold to the state's racing bodies. Today, the majority of the station's programming is dedicated to coverage of thoroughbred, harness and greyhound racing.
