3PB (1925-26)
3PB was Melbourne's second B-Class radio station, opening in September 1925, after 3UZ and before 3DB. The station was originally going to be named 3WR, World Record Company, but that callsign was already being used by 3WR in Wangaratta, which commenced broadcasting on 1 December 1924, and has now evolved into FM station Triple M Goulburn Valley. Most Australian B-Class stations were renamed as Commercial stations in 1930, but 3PB had closed down prior to that date. (This early station has no links whatsoever with the currently-existing 3PB which commenced in 1994 - 3PB now being the official call sign for the Melbourne outlet for ABC NewsRadio.) The original 3PB broadcast between the hours of 8.00 and 10.00 pm, with a power of 1,500 watts. Noel Pemberton Billing The 3PB call sign came from the initials of Noel Pemberton Billing who was a British MP and a highly controversial character in Britain and, to a lesser extent, in Australia, where he immigrated after World War ...

Melbourne
Melbourne ( ; Boonwurrung/Woiwurrung: ''Narrm'' or ''Naarm'') is the capital and most populous city of the Australian state of Victoria, and the second-most populous city in both Australia and Oceania. Its name generally refers to a metropolitan area known as Greater Melbourne, comprising an urban agglomeration of 31 local municipalities, although the name is also used specifically for the local municipality of City of Melbourne based around its central business area. The metropolis occupies much of the northern and eastern coastlines of Port Phillip Bay and spreads into the Mornington Peninsula, part of West Gippsland, as well as the hinterlands towards the Yarra Valley, the Dandenong and Macedon Ranges. It has a population over 5 million (19% of the population of Australia, as per 2021 census), mostly residing to the east side of the city centre, and its inhabitants are commonly referred to as "Melburnians". The area of Melbourne has been home to Aboriginal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brighton, Victoria
Brighton is a suburb in Melbourne, Victoria, Australia, 11 km south-east of Melbourne's Central Business District, located within the City of Bayside local government area. Brighton recorded a population of 23,252 at the 2021 census. Brighton is named after Brighton in England. History In England, on 29 August 1840, Henry Dendy (1800–81) purchased of Port Phillip land at £1 per acre, sight unseen, under the terms of the short-lived Special Survey regulations. Dendy arrived on 5 February 1841 to claim his land. The area was known as Dendy's Special Survey. The area Dendy was compelled to take, called "Waterville", was bound by the coastline to the west and the present day North Road, East Boundary Road and South Road. A town was surveyed in mid-1841, defined by the crescent-shaped street layout which remains today, and subdivided allotments were offered for sale. The area soon became the "Brighton Estate", and Dendy's site for his own home was named "Brighton ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 equipment, 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.

List Of Australian AM Radio Stations
This is an incomplete list of AM broadcast (medium wave) radio transmitter stations in Australia, past and present. History See also main article History of broadcasting in Australia The amateur years In the 1920s transmission on the medium wave band was dominated by amateurs who after qualifying by means of an examination and displaying proficiency in Morse code communication (though the band was restricted to telephony), were issued with a call sign consisting of a number denoting for which State the licence was issued (2=NSW, 3=Vic; 4=Qld; 5=SA and NT; 6=WA; 7=Tas) and a two-letter suffix of their own choosing. A licence fee was paid to the Postmaster General's Department, renewable every five years. Amateurs generally designed and built their own equipment. One such amateur was Tom Elliot, who in 1921 established station 4CM for its owner Dr. McDowall. This would be part of the impetus behind the Queensland Government establishing 4QG, Australia's first Government-owned s ...

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 Austra ...

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 ...

Background Noise
Background noise or ambient noise is any sound other than the sound being monitored (primary sound). Background noise is a form of noise pollution or interference. Background noise is an important concept in setting noise levels. Background noises include environmental noises such as water waves, traffic noise, alarms, extraneous speech, bioacoustic noise from animals, and electrical noise from devices such as refrigerators, air conditioning, power supplies, and motors. The prevention or reduction of background noise is important in the field of active noise control. It is an important consideration with the use of ultrasound (e.g. for medical diagnosis or imaging), sonar, and sound reproduction. Other uses In astronomy, background noise or cosmic background radiation is electromagnetic radiation from the sky with no discernible source. In information architecture, irrelevant, duplicate or incorrect information may be called background noise. In physics and telecommunicat ...

Revolutions Per Minute
Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or with the notation min−1) is a unit of rotational speed or rotational frequency for rotating machines. Standards ISO 80000-3:2019 defines a unit of rotation as the dimensionless unit equal to 1, which it refers to as a revolution, but does not define the revolution as a unit. It defines a unit of rotational frequency equal to s−1. The superseded standard ISO 80000-3:2006 did however state with reference to the unit name 'one', symbol '1', that "The special name revolution, symbol r, for this unit is widely used in specifications on rotating machines." The International System of Units (SI) does not recognize rpm as a unit, and defines the unit of frequency, Hz, as equal to s−1. :\begin 1~&\text &&=& 60~&\text \\ \frac~&\text &&=& 1~&\text \end A corresponding but distinct quantity for describing rotation is angular velocity, for which the SI unit is the ra ...

Shellac
Shellac () is a resin secreted by the female lac bug on trees in the forests of India and Thailand. It is processed and sold as dry flakes and dissolved in alcohol to make liquid shellac, which is used as a brush-on colorant, food glaze and wood finish. Shellac functions as a tough natural primer, sanding sealant, tannin-blocker, odour-blocker, stain, and high-gloss varnish. Shellac was once used in electrical applications as it possesses good insulation qualities and it seals out moisture. Phonograph and 78 rpm gramophone records were made of it until they were replaced by vinyl long-playing records from 1948 onwards. From the time it replaced oil and wax finishes in the 19th century, shellac was one of the dominant wood finishes in the western world until it was largely replaced by nitrocellulose lacquer in the 1920s and 1930s. Etymology ''Shellac'' comes from ''shell'' and ''lac'', a calque of French , 'lac in thin pieces', later , 'gum lac'. Most European langua ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
