95.1 K-SKY began broadcasting in August 1982  from a tower on the summit of Terry Peak in Lead, South Dakota giving the station a very large coverage area that reaches parts of five states. K-SKY uses a 17,000 watt booster licensed to Rapid City with the call letters KSQY-FM1 to help cover the Rapid City metro with a stronger signal.
The original K-SKY studios were located at 666 Main Street in downtown Deadwood. In 1998, Haugo Broadcasting (owner of KSQY) acquired Rapid City stations KIQK "Kick 104" and KTOQ "K-Talk 1340" from Tom-Tom Communications, then owned by NBC news anchor Tom Brokaw. Soon after the purchase, KSQY moved its studios to Rapid City and joined its new sister stations. In Sept 2008, Haugo Broadcasting moved into its new facilities at 3601 Canyon Lake Drive.
