On March 17, 1957, the station signed on as WQXT-FM, the FM counterpart to WQXT (now WPBR), under the ownership of the Flame Radio & TV Corporation..^[5] They simulcast a full service middle of the road format of adult popular music and news, with national shows from the ABC Radio Network. The studios were located on Lake Worth Beach.

In 1963, WQXT-AM-FM were sold to Fairfax Broadcasting.^[6] The following year, the FM station's call sign was changed to WWOS, standing for "Wonderful World of Stereo," when the station began broadcasting in FM stereo full time. In 1971, the simulcast with WQXT ended, as WWOS switched to Progressive Rock using the call letters WMUM for "The Mother."

WJNO-FM, WRMF

The station was sold in 1971 to Robert M. Weeks, who also owned WJNO (now WBZT).^[7] The FM station became WJNO-FM, "J-98", switching to an album rock format.

WJNO-AM-FM were acquired by Richard M. Fairbanks in July 1979.^[8] The FM station's call letters were changed to WRMF in January 1980, representing the owner's initials. Nearly a year later in December 1980, WRMF dropped its album rock format and switched to an adult contemporary format.^[9] When the 1990s rolled along, its format would later begin picking up the tempo and its format moved into a hot adult contemporary format by the middle of the decade.
