From 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). The outsourced Australian Broadcasting Company supplied programs from 1929. In 1932 a commission was established, merging the original ABC company and the National Broadcasting Service. 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.
The beginnings of Radio National lie with Sydney radio station 2FC,[1] which aired its first test broadcast on 5 December 1923 and officially went to air on 9 January 1924.[2] 2FC stood for Farmer and Company, the original owner of the station before the ABC bought the station in 1937.[3]
The ABC then rolled out a national network across the country, somewhat similar in nature to the BBC National Programme.[3] The origins of the other stations in the network were:
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 three times that of the power into the antenna; thus power today would be stated as about 1.7 kW). They used a MT7A valve for the final high power RF stage and a MT7B for the modulator. The power supply was 12,000 volts from three phase power rectified by MR7 valves. 4QG commenced with a 500 Watt transmitter which continued for about 6 months until the 5 kW unit was commissioned.[6]
The radio transmitters for 3AR and 2FC were upgraded to 10 kW in a contract let in 1938 to STC. The transmitters were designed by Charles Strong in London, and were notable in using negative feedback to ensure a high quality flat frequency response.[7]
From 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. It contained most of the ABC's national programming.[citation needed]
The power level of 2FC and 3AR was upgraded to 50 kW in the early 1950s. The transmitters for these were housed in the same building as the radio 1 network. They were manufactured by STC. The final stage contained three parallel 3J/261E air cooled triodes running in class C amplifier at 90% efficiency. These were driven by a class B push-pull modulator with the same type of valves.[8] That of 5CL had to wait until late 1961, when a new joint facility with 5AN was opened at Pimpala.[citation needed]
In the 1970s, the network's program format began to take on a more serious tone, a style which continues to this day. Art critic Peter Timms later remarked that the network is "virtually the only non-print media forum for art in this country".[9]
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).[citation needed] In 1985, the ABC renamed "Radio 2" as "Radio National".[10][3]
Since 1990, all Radio National stations have had the same callsign, "RN".[10]
As 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.[11]
In 2008, controversial programming changes once more raised the issue of funding cuts to the public broadcaster.[12][13][14][15] Presenter Stephen Crittenden leaked confidential programming changes in an unscheduled live broadcast before the start of his show, criticising his superiors.[16] He was suspended for his outburst,[17] and his unscripted comments were cut from Radio National's podcast and transcript of the program. Religious commentator Paul Collins on crikey.com subsequently echoed Crittenden's fears.[18] Crittenden was reinstated in 2009 as a reporter on Background Briefing, after a settlement was reached.[19] However, his program and the other eight programs that had been cancelled or merged were not re-instated that year. The head of ABC Radio, Sue Howard, was dismissed in 2009.[20]
In January 2012 Radio National was rebranded as RN, partly in recognition of the station's growing digital audience. RN has also been used as shorthand for the station's name by many presenters going back several years. RN's tagline, which has changed regularly over the years, was also changed to "Your World Unfolding" to mesh with the station's new logo and visual identity.[citation needed]
In 2012 a new Religion and Ethics report was launched, hosted by Andrew West. The Media Report was also relaunched, hosted by broadcaster and former Life Matters host Richard Aedy.[21] The Media Report was, however, cancelled again in 2015.[22]
In late 2016, the new head of the ABC, Michelle Guthrie, defended the removal of staff and programmes from the Radio National 2017 schedule.[23][24][25] In January 2017 the schedule was reduced in scope due to loss of staff and programmes.[citation needed]
Radio National broadcasts national programming in subjects that include news and current affairs, the arts, social issues, science, drama and comedy. Some programs are relayed on Radio Australia, the ABC's international broadcasting service which was transmitted on shortwave until January 2017, as well as 24-hour FM stations, local relay stations and live satellite.[26]
All radio programs are available for live streaming over the Internet, and most (excluding drama, poetry and music) as audio-on-demand, or for download as MP3s for at least four weeks after broadcast. Some programs are available as MP3s going back to 2005, when Radio National commenced podcasting.[citation needed]
Some of the following programs, listed in order of start date, are aired on both Radio National and ABC Local Radio networks.
