Originally broadcasting from radio mast in Fremantle, the station moved its transmission mast to Coffee Point in South Perth in 1940 to give better reception to listeners north of Perth.By the 1960s, 1970s and 1980s broadcast a Top 40 format on 990 kHz. The station secured significant listener market (AC Neilson) share despite a rival station (96FM) gaining a monopoly on the FM band in the 1980s.On 31 December 1990, the station was one of two additional Perth radio stations to gain a licence to convert to the FM band. They became 92.9 6PM-FM; then subsequently PMFM. The official call sign was changed to 6PPM for regulatory purposes to reflect the move to FM. During most of the 1990s PMFM was Perth's number one radio station.
