 By 1964 KIOA had settled down into its new studios and was under the leadership of program director Peter McLane, who would lead the station until 1977.Under the new leadership of McLane, coupled with Dick Vance leaving KSO to purchase KDMI, KIOA surged back into its spot on top of the ratings.Shortly thereafter, KSO switched to a MOR format and the only competition for KIOA would be KDMI on the FM band.
