Miami’s WIOD-FM signed on in 1946 as the sister station of WIOD-AM.
In 1959, owner Cox-Knight Broadcasting flipped WIOD to a rock format as WCKR, branded as “Wacker Radio.” The FM station simulcast the format. The strategy failed and WCKR flipped back to a middle-of-the-road sound as WIOD in 1962.
The FM simulcast continued until 1971 when WIOD-FM became WAIA-FM, carrying an adult contemporary format. Branded as “A-1-A - Your Music Way” (A1A is a major road along Florida’s Atlantic coast), the station carried light pop and rock.
The station flipped to rock in 1986 as WGTR-FM. In 1990, it became Adult Top 40 WFLC, branded “97.3 The Coast.” In 2014, the station evolved to a Top 40/CHR format as “Hits 97-3.”
As of 2014, Cox Media Group owns the station.
