KRMG maintains the only "staffed 24-hours" newsroom in Tulsa.
Formerly, 102.3 was known as "Spirit 102.3", a Christian radio station. The station played a mix of Christian adult contemporary music from the 1980s through 2009, when it was dropped for a simulcast of sister KRMG.
KRMG is a Fox News affiliate, with local weather provided by sister television station KOKI.
KRMG-FM's format history includes alternative rock as KTOW, which later flipped to urban contemporary in the early 1990s as "Mix 102.3", giving Tulsa its first urban station on the FM dial since KKUL-103.3 left the air in the late-1970s. KTOW was sold in the mid-1990s to Bill Payne and the format was changed to classic country as KTFX which had formerly been at 103.3 and was also owned by Payne, who sold the station to Cox Radio. Cox Radio purchased KTFX-102.3 from Payne and changed the format to rock music as KRTQ "Rock 102.3" to compete against heritage rocker KMOD-FM. In 2005 KRTQ dropped its rock format and changed to Contemporary Christian music as KKCM, competing against heritage Contemporary Christian station KXOJ-FM.
On Monday, March 16, 2009, the Contemporary Christian format was dropped for a simulcast of sister KRMG. The Contemporary Christian format can still be heard on KWEN-HD2 and on Cox Digital Cable channel 962.
