KKDA-FM (104.5 MHz), known on air as K104, is a radio station in the Dallas–Fort Worth metroplex broadcasting an urban contemporary format.

KIXL (pronounced "Kicksil") aired a successful beautiful music format, simulcast on both 104.5 FM and 1040 AM ("104 on both dials").

In 1973, the year Dallas and Fort Worth were combined into one radio market, KIXL dropped its heritage calls in favor of KEZT, continuing to play easy-listening musical fare.

The change did not improve the station's fortunes, as KEZT never appeared in the top 10 of the Dallas/Fort Worth ratings, while KOAX's success continued and KTLC provided additional competition in the beautiful music format.

On December 22, 1976, KEZT flipped to an Rhythmic CHR format, changed their call letters as KKDA-FM and adopted the moniker K104, under the leadership of new owner Hyman Childs.

Today, KKDA-FM is one of the few remaining major market commercial stations in the nation that is still owned by a local, non-corporate broadcaster.
