97.3 FM (call sign: 4BFM) is a commercial radio station in Brisbane, Australia. It is a 50/50 joint venture between DMG and ARN, who jointly purchased the license at auction for $67M.
97.3 FM plays current hits and a variety of 70s, 80s and 90s music (Hot Adult Contemporary), primarily targeted at the 25-54 age group, the group most valued by advertisers. Brisbane's 97.3 FM is part of the Mix Network with sister stations in other major Australian cities - Mix 106.5 Sydney, Mix 101.1 Melbourne, Mix 102.3 Adelaide and Mix 106.3 Canberra.
The addition of DAB AAC+ Digital Radio to Brisbane means that 97.3 FM and its co-owned Classic Hits 4KQ will both be available on the digital format. The additional channel to be provided by 97.3 is called "The Edge Digital", a digital format revamp of the ARN owned Edge 96.1 in Western Sydney.
The station's headquarters in Brisbane is located in the inner south-eastern suburb of Greenslopes on Logan Road.
