In January 1988, KIOV changed call letters to KKLS-FM, and flipped to adult contemporary as "Class FM".

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.

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.
