It broadcast throughout the 1970s and 1980s, mainly from studios in Radio House in Lower Stuart Street (central Dunedin).

Broadcasting on 95.4 MHz, its purpose was to air 4XO programming with a local breakfast show opt-out for Mosgiel and the Taieri Plains.

Bunting left after around two years, seemingly frustrated with the management's decision to aim for an older audience to avoid direct competition with 98 More FM.

The final breakfast team before 4XO became 97.4 More FM was Damian Newell, Breffni O'Rourke and Grant McLean.

Damian Newell continued to host the More FM breakfast show until April 2015, when he moved to 98.2 The Breeze.
