Tulsa Radio: Call Letters To Shuffle at Country Stations

Griffin Media will swap the call letters of its two country music radio stations in Tulsa effective January 5, 2026, as part of preparations to celebrate the 100th anniversary of the iconic KVOO calls in 2026.

The heritage KVOO calls, which originated on AM 1170 in June 1926 and later moved to 98.5 FM, will transfer to the Classic Country outlet at 99.5 FM (currently KXBL, branded as "Big Country 99.5").

Meanwhile, the 98.5 FM station (currently KVOO, branded as "98.5 The Bull") will adopt the KXBL calls to better align with its modern country "Bull" branding.

This change honors the historic legacy of KVOO, a pioneering country station that broadcast live from Cain’s Ballroom with legends like Bob Wills and helped launch careers of artists including Reba McEntire, Garth Brooks, Toby Keith, and Blake Shelton.

The swap will not affect programming, personalities, or formats. 

Griffin Media Director of Radio Operations & Programming Don "DC" Cristi described it as "an incredible honor to carry forward the legacy of KVOO" while enhancing brand alignment for both stations.
