To achieve coverage of all of its franchise area, it requires six transmitters including stations at Bray Head, Wicklow Head, Avoca, Arklow, Baltinglass and a transmitter located at Slieve Thoul in Saggart County Dublin where the Wicklow, Kildare and Dublin borders meet.

[citation needed] East Coast FM began as BLB (Bray Local Broadcasting) in 1984.

[citation needed] In 2002, the station was renamed from "East Coast Radio" to "East Coast FM" and moved from its Victorian premises at Prince of Wales Terrace on Quinsboro Road, Bray (where it had been located since 1985) to a state-of-the-art radio centre complex in Ballywaltrim, Bray.

[2] BLB has also operated out of a rooftop office on top of what is now Katie Gallagher's pub on Strand Road in the early 1980s.

[citation needed] As of December 2007, Communicorp reportedly holds a 30% share in the station.
