KWFF

It is owned by Champlin Broadcasting, Inc. KWFF's studios and offices are on NW 64th Street in Oklahoma City.

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.

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.
