Saor Raidió Chonamara

Saor Raidió Chonamara (Free Radio Connemara) was an Irish language pirate radio station that was formed out of frustration over the lack of Irish-language media by the civil rights movement Gluaiseacht Cearta Sibhialta. The station started broadcasting on Easter Sunday 1970 to considerable press coverage, gaining notoriety in the process. It was even featured in the Irish Independent. Because these transmissions throughout the Gaeltacht were illegal (RTÉ had the monopoly at the time), the station continued in total secrecy with the transmitter and studio being transported by Honda 50 to stay one step ahead of the law.

The station's considerable success was enough to force the Irish Government to establish RTÉ Raidió na Gaeltachta in response, proving that there was a need for a station.
