The station signed on the air on July 11, 1964, as KELO-FM. After a 52-year history in Sioux Falls radio, Midcontinent sold all of its stations, including KELO-FM, to Backyard Broadcasting of Baltimore in 2004. It marked the company's exit from broadcasting, having sold off
KELO-TV in 1996. Backyard sold its seven Sioux Falls stations in 2012 to their present owner,
Midwest Communications, in a $13.35 million transaction. On October 28, 2013, KELO-FM and its
adult contemporary format moved to
101.9 FM, swapping frequencies with KTWB and its
country format. ==References==
