Owned and operated by ARN, it broadcasts a contemporary hit radio format to Launceston and surrounding areas.
The station was set up in 1938 by The Examiner newspaper and shared a fierce rivalry with rival 7LA, splitting the city's audience through much of the 1980s.
In 2002, television station ABNT-3 vacated VHF channel 3, opening up space for further FM radio services in Launceston.
In November 2021, Chilli FM, along with other stations owned by Grant Broadcasters, was acquired by the Australian Radio Network.
This deal allowed Grant's stations, including Chilli FM, to access ARN's iHeartRadio platform in regional areas.
