RTÉ Radio: A History of Irish Broadcasting
The evolution of radio in Ireland is a journey from modest experimental broadcasts to a sophisticated nationwide network. What began as a small-scale operation in the 1920s has transformed into RTÉ (Raidió Teilifís Éireann), the national broadcaster providing a diverse array of news, music, and cultural programming to the Irish public.
The Early Years: From 2RN to Radio Éireann
The story of Irish radio began on 14 November 1925, with the first voice broadcast of 2RN, the original callsign for what would eventually become RTÉ Radio 1. Station director Seamus Clandillon made the historic announcement: "Seo Raidió 2RN, Baile Átha Cliath ag tástáil" (This is Radio 2RN, Dublin calling/testing). While regular broadcasting officially commenced on 1 January 1926, the initial 1.5 kilowatt signal was insufficient to reach most of the country.
Technical limitations led to early friction, particularly in Cork, where listeners struggled to tune in. In response to these complaints, Clandillon noted in The Irish Radio Review that some listeners simply did not know how to operate their radio sets. To expand coverage, a second station, 6CK, was established in Cork in 1927 to relay 2RN transmissions.
A major leap in accessibility occurred in 1932 with the establishment of a high-power 60 kW station in Athlone, timed to coincide with the Eucharistic Congress. This network—comprising 2RN, 6CK, and the Athlone station—became known as "Radio Athlone" (Raidió Áth Luain), making broadcasts receivable across nearly all of Ireland. In 1938, the service was officially renamed Radio Éireann.

Growth and Modernization
For several decades, Radio Éireann operated under a conservative programming policy and limited hours, leading many listeners to prefer the BBC or Radio Luxembourg. This dynamic shifted in 1960 when the service was freed from direct government control.
Infrastructure also needed an upgrade. Since 1928, studios had been located in the rebuilt GPO on O'Connell Street in Dublin. As the service outgrew these cramped quarters, plans were made for a new facility. Construction on the Radio Centre in Donnybrook began in June 1969 and was completed by April 1971. Live broadcasts from the new site began on 24 September 1973, and by May 1974, most programming had migrated. The final link to the GPO ended on 8 November 1976, when the Henry Street studios ceased continuity announcements.
Diversification of Channels
As listener tastes evolved, RTÉ expanded its offerings to include specialized channels:
- Raidió na Gaeltachta: Launched on 2 April 1972, this Irish language channel has become an influential source for news, music, and spoken word.
- RTÉ 2fm: Originally launched as RTÉ Radio 2 on 31 May 1979, this pop music and chat channel was created to compete with the rise of pirate radio.
- RTÉ lyric fm: Debuting in May 1999, this station focuses on classical music and the arts, replacing FM3 Classical Music.
RTÉ also experimented with local broadcasting, operating RTÉ Radio Cork (also known as Cork 89FM or RTÉ Cork Local Radio), which served the Cork region until its closure in January 2000.
