The first voice broadcast of 2RN, the original radio callsign for RTÉ Radio 1, took place on 14 November 1925 when Seamus Clandillon, the 2RN station director said, 'Seo Raidió 2RN, Baile Átha Cliath ag tástáil', Irish for 'This is Radio 2RN, Dublin calling'. Regular Irish radio-broadcasting began on 1 January 1926. Unfortunately, most Irish people could not receive 2RN's (1.5 kilowatt) signal. When faced with numerous complaints from Cork regarding the writers' inability to tune to the signal, Clandillon remarked in The Irish Radio Review, a magazine dedicated to the service, that they did not know how to operate their sets. 6CK was established in Cork in 1927; however 6CK was mostly a relay of 2RN.
All of RTÉ's stations are broadcast on mux 1 of the Irish digital radio system, as well as being streamed online.

A high power (initially 60 kW) station was established in Athlone, in 1932, to coincide with the staging of the Eucharistic Congress. 2RN, 6CK and Athlone became known as "Radio Athlone" or, in Irish, "Raidio Áth Luain" and were receivable across virtually the entire country. Radio Athlone became known as "Radio Éireann" in 1938.
Radio Éireann tried to satisfy all tastes on a single channel (with very limited programming hours). However, this resulted in a rather conservative programming policy. It was barely tolerated by most Irish listeners, and usually trounced (particularly on the east coast and along the Northern Ireland border) by the BBC and later Radio Luxembourg. This did not really change until Radio Éireann became free of direct government control in the 1960s.
In June 1969, work had begun on the Radio Centre. Planning and equipping the building took many years. The new Radio Centre at Montrose was completed in April 1971 and live radio broadcasts from Montrose began on 24 September 1973. The move began from the GPO in O'Connell Street, which had been the home of radio since 1929.
Now, RTÉ has a nation-wide communications network with an increasing emphasis on regional news-gathering and input. Broadcasting on Radio 1 provides comprehensive coverage of news, current affairs, music, drama and variety features, agriculture, education, religion and sport, mostly in English but also some Irish. RTÉ 2fm is a popular music and chat channel which commenced broadcasting as RTÉ Radio 2 on 31 May 1979, Brendan Balfe being the first voice to be heard on the station at midday, when he introduced the first presenter, Larry Gogan. RTÉ lyric fm serves the interests of classical music and the arts, coming on air in May 1999, and replacing FM3 Classical Music, which had catered for the same target audience and time-shared with RTÉ Raidió na Gaeltachta, an exclusively Irish language service, which first began broadcasting on Easter Sunday, 2 April 1972. Formerly RTÉ operated RTÉ Radio Cork (previously 'Cork 89FM' and 'RTÉ Cork Local Radio'), a local radio service in Cork, but this closed down in the early 2000s.
RTÉ operates multiplex 1 (block 12C) on the Irish digital radio platform (DAB), having launched nine digital-only channels from May 2007 as part of a trial to see what demand existed for new radio services. Most of the channels were an extension of the main Radio 1 and 2fm stations, focusing on particular genres. On 30 November 2008 the trial was brought to an end with the commercial multiplex (mux 2/block 12A) being suspended pending regulatory guidance, while RTÉ also changed the line up of its stations. The day after the end if the trial, two of the stations were turned off, with six being officially launched, namely RTÉ 2XM, RTÉ Chill/RTÉ Junior (timeshare), RTÉ Choice, RTÉ Gold, and RTÉ Pulse.
The two stations that were ended were RTÉ Digital Radio News, which played the most recent Radio 1 news bulletin on loop and RTÉ Playback, a listen again service with content from Radio 1 and 2fm. Despite not officially being launched, the RTÉ Radio 1 Extra service also continues to be broadcast, however the AM Radio 1 service has traditionally been used for opt-out programmes, although it was not called Radio 1 Extra until the trial.
At the moment, only 44% of the country is able to pick up the RTÉ DAB service, mainly in greater Dublin, Limerick and Cork areas. Despite this limited output from DAB, RTÉ's radio stations are broadcast on digital and cable television, and will also be included in the new digital terrestrial television (DTT) service to be launched in 2009.
A survey carried out by the Department of Community, Rural and Gaeltacht Affairs showed that demand for an Irish-language radio station aimed at a younger audience than RTÉ Raidió na Gaeltachta was high. This means that RTÉ might have plans to launch such a radio station.
