In the late 1950s, the station's call letters were "KKIS." On January  1, 1960, Kay Kis Corporation assumed ownership of the station. The two principal owners were Len and Burrell Small (their grandfather was a former Illinois governor). The general manager was Jerry Bassett, who previously managed radio station WISC in Madison, Wisc. The station had the call letters KIXA on August 17, 1990. On September 8, 1993, the station changed its call sign to the current KATD as a rebroadcast of KIQI. Prior to 1990, this frequency was occupied by KKIS, which was playing Adult Top 40/Hot AC music as late as 1985 .
