On February 1, 1981, the station
signed on the air. It was originally licensed to
Alva, Oklahoma, and used the
call sign KXLS. The station was owned by Zumma Broadcasting and aired a
middle of the road music format, primarily serving
Enid and surrounding communities. The owners eventually got permission from the
Federal Communications Commission (FCC) to move the station closer to Oklahoma City to improve its value, with the ability to sell advertising in the more lucrative, larger
radio market. The transmitter was relocated northwest of Oklahoma City, with the
city of license changed to the suburb
Mustang, Oklahoma. In December 2022, KWFF added The Gospel Station to its HD4 subchannel. The station previously aired an
oldies format as KZLS “True Oldies 99.7". It switched to
classic country in late September 2013, using Envision Radio Networks'
Hank FM branding. On May 26, 2023, the then-KNAH rebranded as "99.7 The Wolf", and shifted its playlist to include more current country music, while still maintaining a classic-heavy focus. The station changed its call sign to KWFF on July 2, 2023. ==References==
