Phantom FM began broadcasting to Dublin in 1997 from a garden shed in Sandyford. (previously it had broadcast under various names including Spectrum FM from Ballybrack) Arguably one of the most successful pirate stations of the 1990s, Phantom played mainly indie music which had a huge underground following in Dublin. This market which was completely ignored by the mainstream radio stations at the time which accounts for the success Phantom enjoyed. The unlicensed Phantom FM came to an end in the May 2003 crackdown on Dublin pirate radio stations. One of two transmitter sites used at the time by Phantom was raided by Comreg, however, the studio in the city centre was untouched. Phantom briefly returned to the air on the Sunday afternoon following the raids, with a broadcast of its 'Anorak' programme, before finally closing as a pirate.
