2CM
2CM was an experimental Australian broadcasting station operated by Charles Dansie Maclurcan. In 1921, 2CM became the first Australian station to regularly broadcast music and talk. (However, Ernest Fisk (later Sir Ernest) of AWA – Amalgamated Wireless (Australasia) did conduct an isolated experiment in which music was History of broadcasting, broadcast, in 1906). In some quarters Maclurcan has been called ''Australia’s leading radio amateur''. History The electrical engineering firm of Maclurcan and Lane was issued an experimental licence in 1910. The principals of the firm were Charles Dansie Maclurcan and his brother-in-law Cyril Herbert Dodson Lane; Both were wireless experimenters and the firm traded with other Sydney area wireless experimenters, although this was a minor part of their business. The station was established on the roof of the Wentworth Hotel and both were involved in transmission and reception from the station. A major fire started in the station's e ...

History Of Broadcasting In Australia
The history of broadcasting in Australia has been shaped for over a century by the problem of communication across long distances, coupled with a strong base in a wealthy society with a deep taste for aural communications in a silent landscape. Australia developed its own system, through its own engineers, manufacturers, retailers, newspapers, entertainment services, and news agencies. The government set up the first radio system, and business interests marginalized the hobbyists and amateurs. The Labor Party was especially interested in radio because it allowed them to bypass the newspapers, which were mostly controlled by the opposition. Both parties agreed on the need for a national system, and in 1932 set up the Australian Broadcasting Commission, as a government agency that was largely separate from political interference. The first commercial broadcasters, originally known as "B" class stations were on the air as early as 1925. Many were sponsored by newspapers in Austr ...

Timeline Of Australian Radio
1800s 1890-1899 * Although Australia's first officially recognised experimental broadcast was made in 1905 (see below), there are reliable reports in September 1897 (just two years after Guglielmo Marconi's original radio experiments) of demonstrations of wireless communication in Australia conducted by Professor William Henry Bragg of Adelaide University following experiments by Bragg, and at some stage in conjunction with G.W. Selby of Melbourne. 1900s 1900-1909 *1901: The six states federate into the Commonwealth of Australia. Section 51(v) of the Australian Constitution gives the federal government power over "postal, telegraphic, telephonic, and other like services". *1905: **''Wireless Telegraphy Act (1905)'' placed broadcasting in the control of the Australian Government. This has remained in place ever since. **Italian Guglielmo Marconi’s company builds Australia's first two-way wireless telegraphy station at Queenscliff, Victoria. *1906: first official transmissi ...

History Of Broadcasting
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.''Australian Radio History'', Bruce Carty, Sydney, 2011 The radio broadcasting of music and talk intended to reach a dispersed audience started experimentally around 1905–1906, and commercially around 1920 to 1923. VHF (very high frequency) stations started 30 to 35 years later. In the early days, radio stations broadcast on the longwave, mediumwave and shortwave bands, and later on VHF (very high frequency) and UHF (ultra high frequency). However, in the United Kingdom, Hungary, France and some other places, from as early as 1890 there was already a system whereby news, music, live theatre, music hall, fiction readings, religious broadcasts, etc., were available in priv ...

History Of Telecommunications In Australia
Telecommunications in Australia refers to communication in Australia through electronic means, using devices such as telephone, television, radio or computer, and services such as the telephony and broadband networks. Telecommunications have always been important in Australia given the 'tyranny of distance' with a dispersed population. Governments have driven telecommunication development and have a key role in its regulation. History Colonial period Prior to Federation of Australia in 1901, each of the six Australian colonies had its own telephony communications network. The Australian networks were government assets operating under colonial legislation modelled on that of Britain. The UK Telegraph Act 1868 for example empowered the Postmaster-General to 'acquire, maintain and work electric telegraphs' and foreshadowed the 1870 nationalisation of competing British telegraph companies. Australia's first telephone service (connecting the Melbourne and South Melbourne office ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Radio
The early history of radio is the history of technology that produces and uses radio instruments that use radio waves. Within the timeline of radio, many people contributed theory and inventions in what became radio. Radio development began as " wireless telegraphy". Later radio history increasingly involves matters of broadcasting. Discovery In an 1864 presentation, published in 1865, James Clerk Maxwell proposed theories of electromagnetism, with mathematical proofs, that showed that light and predicted that radio and x-rays were all types of electromagnetic waves propagating through free space. Between 1886 and 1888 Heinrich Rudolf Hertz published the results of experiments wherein he was able to transmit electromagnetic waves (radio waves) through the air, proving Maxwell's electromagnetic theory.

Short Wave
Shortwave radio is radio transmission using shortwave (SW) radio frequencies. There is no official definition of the band, but the range always includes all of the High frequency, high frequency band (HF), which extends from 3 to 30 MHz (100 to 10 metres); above the Medium frequency, medium frequency band (MF), to the bottom of the Very high frequency, VHF band. Radio waves in the shortwave band can be reflected or refracted from a layer of electrically charged atoms in the atmosphere called the ionosphere. Therefore, short waves directed at an angle into the sky can be reflected back to Earth at great distances, beyond the horizon. This is called skywave or "skip" radio propagation, propagation. Thus shortwave radio can be used for communication over very long distances, in contrast to radio waves of higher frequency, which travel in straight lines (line-of-sight propagation) and are limited by the visual horizon, about 64 km (40 miles). Shortwave broadcasts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2BL (AM)
ABC Radio Sydney (official call sign: 2BL, formerly 2SB) is an ABC radio station in Sydney, Australia. It is the flagship station in the ABC Local Radio network and broadcasts on 702 kHz on the AM dial. The station transmits with a power ( CMF) of 3,110V, which is equivalent to 50 kW (the maximum permissible in Australia) from a site west of the Sydney CBD. History ABC Radio Sydney is the first public radio station in Australia opened in Sydney at 8:00pm on 23 November 1923. Its first callsign was ''2SB'' where ''2'' denotes the State of New South Wales and ''SB'' stood for Sydney Broadcasters Limited. However, the callsign was soon altered to ''2BL'' for Sydney Broadcasters Limited. The change was due to the audio similarity of the sounds FC and SB. In May 1928 the Sydney Broadcasting Company was formed to take over stations 2BL and 2FC. A year later a consortium of entertainment companies founded the Australian Broadcasting Company Limited (ABC) to supply pro ...
