The station currently airs a classic hits format and is branded on-air as 103.9 Max FM.

In 1979, the Maritime provinces only had a handful FM terrestrial radio stations: CFBC-FM, CKWM-FM, CJCB-FM, CBC Stereo (CBH-FM), CHFX-FM, and CIOO-FM.

Late evening and weekend blocks were set aside for specialty variety programs such as journals, classical and French music which abided by its licence requirements and agreements.

John Richard (JR) took the helm as morning drive DJ in 1980, and lead to successful ratings periods for the station.

Until new facilities for MBS Radio (formerly Eastern Broadcasting) were built in 1981, both stations operated from the Assumption Complex in downtown Moncton.

Subsequently, after CKCW left its downtown location in July 1981, a private French radio station, CHLR-AM, began broadcasting from the former studios in October of that same year.
