WWJK (107.3 FM, "107.3 JACK fm") is an adult hits formatted radio station located in Jacksonville, Florida. The station is owned by iHeartMedia, Inc.. The station's studios are located on Central Parkway in Jacksonville's Southside section, and the transmitter is in the Arlington section.
The station had originally signed on in May 1977 as beautiful music WJEE, but became country as WCRJ in 1981. In 1991, the call letters changed to WROO ("Rooster Country"), then on December 19, 2005, it became the new home for modern rock station WPLA ("Planet Radio").
