Athens Broadcast Company (H. F. Dunnavant), owners of 730 AM, WJMW, received a permit for a new FM station in May of 1958, for a Class A signal running 1.056 kW from a Gates BF-1A from the top of the existing AM tower on Hines Street in Athens, for 104.3 MHz.  The station went on the air later that year as WJMW-FM.  The calls changed to WJOF in 1958, and it's likely that the station had an automated Easy Listening format from this point onwards. 

The station got a boost in power to 50 kW in the summer of 1965.  They used a Gates FM-10G transmitter and a Gates FMA-6B 6 bay antenna to help increase coverage of the growing Huntsville area. 

The station sought to further increase their coverage in 1977, when they sought a permit to move the FM antenna up to Capshaw Mountain and boost power to 100 kW.  Decatur Telecable filed a petition for reconsideration on the permit, which held up the build-out for several years, and required some compromises such as relocating the antenna and lowering the overall height.  While working through those issues, the format appears to have flipped to Contemporary Hit Radio (CHR) as early as 1978.  That year, the station's legal ID was changed to "WJOF Athens-Huntsville" in anticipation of the full market coverage their mountaintop transmitter would provide.

The Capshaw Mountain facility finally signed on in the spring of 1981.  The station used a Sparta 625A transmitter, which fed a Phelps-Dodge CFM H.P. 10 antenna with 10 bays.  In 1983, the call sign changed to WZYP and it's been hit music ever since.  Later in the 80s, control of Athens Broadcasting was handed to Bill Dunnavant, and under his ownership the station eventually fell into the hands of Cumulus (along with several other area stations) in 2003.
