![]() ![]() In 2008, controversial programming changes once more raised the issue of funding cuts to the public broadcaster. Since 1990, all Radio National stations have had the same callsign, "RN".Īs a result of cuts in the 1996–97 budget, Radio National was hit with a reduction of a million dollars in its funding, with a significant impact on programming. In 1985, the ABC renamed "Radio 2" as "Radio National". In the early 1980s the broadcast footprint was extended with the construction of the first of over 300 regional FM transmitters (including community re-broadcast sites). Art critic Peter Timm later remarked that the network is "virtually the only non-print media forum for art in this country". In the 1970s, the network's program format began to take on a more serious tone, a style which continues to this day. That of 5CL had to wait until late 1961, when a new joint facility with 5AN was opened at Pimpala. These were driven by a class B push-pull modulator with the same type of valves. ![]() The final stage contained three parallel 3J/261E air cooled triodes running in class C amplifier at 90% efficiency. The transmitters for these were housed in the same building as the radio 1 network. The power level of 2FC and 3AR was upgraded to 50 kW in the early 1950s. It contained most of the ABC's national programming. The transmitters were designed by Charles Strong in London, and were notable in using negative feedback to ensure a high quality flat frequency response.įrom 1947 until the mid-1980s, "Radio 2" (as it came to be known) was broadcast to the major metropolitan centres, with a large broadcast footprint in adjacent areas due to the powerful AM transmitters in use. The radio transmitters for 3AR and 2FC were upgraded to 10 kW in a contract let in 1938 to STC. 4QG commenced with a 500 Watt transmitter which continued for about 6 months until the 5 kW unit was commissioned. ![]() The power supply was 12,000 volts from three phase power rectified by MR7 valves. They used a MT7A valve for the final high power RF stage and a MT7B for the modulator. The first transmitters for 2FC, 5CL and 4QG were made by AWA with power of 5 kW (note that until about 1931 in Australia, transmitter powers were defined in terms of DC input to final amplifier, typically about 3 times that of the power into the antenna thus power today would be stated as about 1.7 kW). 4QG Brisbane – 27 July 1925 "Queensland Government" (operated by the Queensland Radio Service, an agency within the Office of the Chief Secretary).5CL Adelaide – 20 November 1924 "Central Broadcasters Ltd".3AR Melbourne – 26 January 1924 "Associated Radio Company of Australia", organised by Esmond Laurence Kiernan and others.The origins of the other stations in the network were: The ABC then rolled out a national network across the country, somewhat similar in nature to the BBC National Programme. 2FC stood for Farmer and Company, the original owner of the station before the ABC bought the station in 1937. ![]() The beginnings of Radio National lie with Sydney radio station 2FC, which aired its first test broadcast on 5 December 1923 and officially went to air on 9 January 1924 (or 1927?). It is from this time that Radio National dates as a distinct network within the ABC, in which a system of program relays was developed during the subsequent decades to link stations spread across the nation. In 1932 a commission was established, merging the original ABC company and the National Broadcasting Service. The outsourced Australian Broadcasting Company supplied programs from 1929. 1937: Predecessors and beginnings įrom 1928, the National Broadcasting Service, as part of the federal Postmaster-General's Department, gradually took over responsibility for all the existing stations that were sponsored by public licence fees ("A" Class licences).
