Pulse FM began life as a garden shed-based radio station, as with others in this list. However, Pulse was driven strongly by commercial forces from the beginning. On air from 1995 to 1999, its existence coincided with a population boom in the 18- to 25-year-old age bracket. Pulse derived much of its income from promoting underage and overage discos in suburban Dublin, and as promoters and operators, the station management made substantial sums from this as well as advertising DJ hire services. Filed accounts at the CRO (No. 288948) confirm the financial success of the station. Its backers invested heavily in CTE transmission and modulation equipment, producing a slick, clean FM sound, clearly received all over the Greater Dublin Area.
