KDLO-FM went on the air in 1968 and was the sister station to KDLO-TV, which was licensed to nearby Florence. Midcontinent Broadcasting owned both stations until 1994, when KDLO-FM was sold to the Sorenson Broadcasting Corporation. Sorenson was later bought by Digity, which in turn sold all its stations to Alpha Media.
On May 22 2024, Alpha cut ties with all local broadcasters of the South Dakota stations. Informing them only after their shift was over they were no longer employed.
