The station first started out as KSKY. It was to sign on in 1960, but most sources say it never did. It was meant to be a simulcast of KSKY-AM. KSKY was offered the 98.7 frequency (now used by KLUV-FM) in 1957 for $75,000, but refused. In 1996, the station changed its call letters to KDTR under a religious format; the callsign was more likely used as temporary before switching to KDKR.
