KKLS-FM

The station signed on in 1975 as KIOV, and aired a country music format. In January 1988, KIOV changed call letters to KKLS-FM, and flipped to adult contemporary as "Class FM". The station later shifted to oldies as "Oldies 104.7". At the time, the station was under ownership of Southern Minnesota Broadcasting.

On December 3, 1997, at 3 pm, after three days of stunting with a loop of "It's the End of the World as We Know It (And I Feel Fine)" by R.E.M., KKLS flipped to its current contemporary hit radio format as "Hot 104.7", filling a format void that was left by KPAT's flip to country in 1993. Prior to the flip, KKCK (then at 99.7 FM, now at 94.7 FM) served as the only contemporary hit radio station in the Sioux Falls market between 1992 and 1997.

In 2003, Southern Minnesota Broadcasting sold their Sioux Falls stations to Cumulus Media. In 2012, it was announced that Cumulus was selling their Sioux Falls stations to Townsquare Media.

Since 2018, Hot 104.7 currently competes against KQSF in the contemporary hit radio format.
