FM Broadcasting In Australia
FM broadcasting started in Australian capital cities in 1947 on an "experimental" basis, using a (monaural) ABC national network feed, consisting largely of classical music and Parliament, as a programme source. FM receivers were expensive and the audience consisted largely of hi-fi enthusiasts. The transmitters (operated by the PMG's Dept) were shut down in 1961, as much of the standard FM band (98–108 MHz) was reserved for TV channel 5 (102.25 video carrier). Early attempts at introduction In April 1948 the Labor government of Ben Chifley indicated that the introduction of FM broadcasts would occur on a nationalised basis with no commercial stations. After the passage of the Broadcasting Act which gave the Federal Government full control of FM in Australia, it was suggested in January 1949 that the Chifley government would "soft pedal" the development of FM radio. In their annual report released on 3 January 1956, the Australian Broadcasting Control Board proposed a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

3MBS
3MBS is an FM radio station in Victoria, Australia, and began transmitting to Melbourne and surrounding areas on 1 July 1975. Since then it has operated successfully as a non-profit community-based organisation broadcasting classical and jazz music. 3MBS also led the way for the introduction of community radio in Australia back in 1968. It is part of the national Australian Fine Music Network. History The increasing popularity of rock music through the late 1950s and 1960s led to a reduction in the amount of classical music played on the ABC and commercial radio stations in Australia. Up until the early 1950s most radio stations employed orchestras to play music which included classical music. By the 1960s, only the ABC supported its own orchestra. But even the ABC had dramatically reduced the amount of classical music on air. A music fan and radio engineer, Brian Cabena, was unhappy about being unable to listen to the music he liked on the radio - and he did something about ...

SBS Radio
SBS Radio is an Australian radio network owned by the Special Broadcasting Service directed towards newly arrived immigrants in Australia. It originally began as two stations based in Melbourne and Sydney, set up to provide pre-recorded information about the then-new Medicare (Australia), Medibank health care system in languages other than English. Nowadays, the network targets the estimated 4+ million Australians who speak a language other than English at home with programs in 68 languages.Our Story : SBS Corporate SBS Corporation Like SBS Television, SBS Radio supplements its government funding with paid-for information campaigns for government agencies and non-profit organisations as well as commercial advertising and sponsorship.

CAAMA
The Central Australian Aboriginal Media Association (CAAMA) is an organisation founded in 1980 to expose Aboriginal music and culture to the rest of Australia. It started with 8KIN-FM, the first Aboriginal radio station in the country. Based in Alice Springs, the organisation is particularly focused on the involvement of the local Indigenous community in its production. CAAMA is involved in radio, television and recorded music. History Origins and Imparja In 1980, CAAMA originally established itself as a public radio station by two Aboriginal people and one " whitefella": Freda Glynn, Phillip Batty, and John Macumba. 8KIN-FM was the first Aboriginal radio station. The success of the station quickly grew, leading its content to extend into music (country music and Aboriginal rock), call-ins, discussion, and news and current affairs. Broadcasts were made in six different languages, alongside English, and operated about fifteen hours every day. Later expansions saw the station m ...

Triple J
Triple J is an Australian government-funded national radio station founded in 1975 as a division of the Australian Broadcasting Corporation (ABC). It aims to appeal to young listeners of alternative music, and plays far more Australian content than commercial networks. The station was set up under the Gough Whitlam government, wanting to extend the appeal of the ABC to young Australians. Initially broadcasting as 2JJ or Double Jay from 19 January 1975, it stood apart from commercial stations with its lack of private advertising and its fringe music programming. Following a transition to FM in 1981, the station rebranded as 2JJJ or Triple J as it expanded regionally throughout the 1990s. Two spin-off digital stations were launched in the early 2010s: Double J aims to appeal to more mature audiences, and Triple J Unearthed plays only unsigned, local musicians. Despite declining ratings in their target 18–24-year-old demographic, Triple J maintains a strong podcast and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ABC Classic FM
ABC Classic, formerly ABC-FM (also ABC Fine Music), 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). History ABC Classic was established in 1976 as "ABC-FM", and later for a short time was known as "ABC Fine Music" (a play on the letters FM). It became known as ABC Classic FM in 1994, before adopting its current name in January 2019. It was the ABC's first experiment in FM broadcasting – which had become a necessity in Australia as broadcasters ran out of AM frequencies on which to transmit. This was before most commercial stations had started using FM, and the ABC was first to use satellite transmissions. The creation of ABC Classic FM was inspired partly by the example of BBC Radio 3, and its focus was on fine music and the arts. ABC Classic FM's studios were establishe ...

Quadrature Amplitude Modulation
Quadrature amplitude modulation (QAM) is the name of a family of digital modulation methods and a related family of analog modulation methods widely used in modern telecommunications to transmit information. It conveys two analog message signals, or two digital bit streams, by changing (''modulating'') the amplitudes of two carrier waves, using the amplitude-shift keying (ASK) digital modulation scheme or amplitude modulation (AM) analog modulation scheme. The two carrier waves are of the same frequency and are out of phase with each other by 90°, a condition known as orthogonality or Quadrature phase, quadrature. The transmitted signal is created by adding the two carrier waves together. At the receiver, the two waves can be coherently separated (demodulated) because of their orthogonality. Another key property is that the modulations are low-frequency/low-bandwidth waveforms compared to the carrier frequency, which is known as the In-phase and quadrature components#Narrowband ...

Television
Television (TV) is a telecommunication medium for transmitting moving images and sound. Additionally, the term can refer to a physical television set rather than the medium of transmission. Television is a mass medium for advertising, entertainment, news, and sports. The medium is capable of more than "radio broadcasting", which refers to an audio signal sent to radio receivers. Television became available in crude experimental forms in the 1920s, but only after several years of further development was the new technology marketed to consumers. After World War II, an improved form of black-and-white television broadcasting became popular in the United Kingdom and the United States, and television sets became commonplace in homes, businesses, and institutions. During the 1950s, television was the primary medium for influencing public opinion.Diggs-Brown, Barbara (2011''Strategic Public Relations: Audience Focused Practice''p. 48 In the mid-1960s, color broadcasting was ...

Radio Frequency
Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency range from around to around . This is roughly between the upper limit of audio frequencies that humans can hear (though these are not electromagnetic) and the lower limit of infrared frequencies, and also encompasses the microwave range. These are the frequencies at which energy from an oscillating current can radiate off a conductor into space as radio waves, so they are used in radio technology, among other uses. Different sources specify different upper and lower bounds for the frequency range. Electric current Electric currents that oscillate at radio frequencies (RF currents) have special properties not shared by direct current or lower audio frequency alternating current, such as the 50 or 60 Hz current used in electrical power distribution. * Energy from RF currents in conduct ...
