WDAF-FM (106.5 FM) is a commercial radio station licensed to Liberty, Missouri, and serving the Kansas City metropolitan area.

Prior to the official sign-on, test transmissions carried the call sign KSAB (standing for "Strauss-Abernathy Broadcasting").

SW Radio Enterprises took over in 1979, flipping the format on November 19, changing call letters to KSAS, branded as "SAS 106+1⁄2".

In March 1983, the station decided to take KYYS head-on, flipping to album rock, and changing the call letters to KKCI.

Three weeks later, the station signed back on and flipped to a soft adult contemporary format, branded as "K-Lite", and changing the call letters to KLTY.

[7] On July 29, 1988, at 2 p.m., after stunting for three days with a loop of "Kansas City" by The Beatles, KLTY flipped back to album rock, changing call letters to KXXR.

[17][18] After the frequency swap, 106.5 FM stunting with all-Garth Brooks music for 16 days, then changed its call sign to KKCJ (instituted on March 9) and moniker to "CJ-106".

This came after the signing of rival WHB sports hosts Jason Whitlock, Bill Maas, and Tim Grunhard.

After a lengthy decision over which radio station to put the AM's country format (which involved sister station KRBZ almost being killed off for it, only to have an executive order issued by Entercom corporate management in response to overwhelming listener turnout halting that), it was announced that KCIY would flip back to country.

[29] At noon on August 10, 2003, after a 6-hour farewell show (and playing "Neither One of Us" by Gladys Knight & the Pips), WDAF began simulcasting on both 610 AM and 106.5 FM, for a one-month period until the sports talk format on 610 AM finally debuted on September 10.

[32] On December 5, 2019, it was announced that WDAF-FM would become the flagship radio station of the Kansas City Chiefs with the start of the 2020 season, directly off their win in Super Bowl LIV, after the expiration of a 30-year deal with Cumulus Media's KCFX (101.1).

Sister station KCSP carries wrap-around coaches and players programming and also simulcasts select games.
