Its original call sign was KXOJ-FM. It was the sister station to KXOJ 1550 AM. They were owned by KXOJ, Inc. The AM station had a full service format of middle of the road music, with local news and sports. KXOJ-FM aired a Christian radio format. It was only powered at 2,000 watts, a fraction of its current output and only audible in and around Sapulpa. A new tower was constructed for the station in 2014. It is between Glenpool and Sapulpa, near U.S. The tower was part of an FCC granted Class C3 upgrade, increasing the station to an ERP of 19,000 watts. The transmission also includes an HD signal that covers the Tulsa metro area. Previously, KXOJ operated from a 361-foot tower near Sapulpa, operating at only 5,000 watts. Several inner-ring Tulsa suburbs such as Broken Arrow, Claremore and Okmulgee only got a grade B signal. Over time, the Christian talk and teaching shows were cut back, making KXOJ-FM a full time Christian Contemporary outlet. Every morning between 6 and 10am KXOJ-FM's on-air lineup included Dave Weston and Katie Rindt. Other veteran announcers included Bob Michaels, who joined the station in 1998, and Gary Thompson 3pm to 7pm, who began intermittently working there in the early 1990s. After many years in morning drive, Heather Miles moved to the 10a to 3p shift in January 2016. Despite the signal limitations, KXOJ-FM won three Dove Awards as Station of the Year.
