[1] In its early years, KQHU programmed popular standards and beautiful music;[3] by 1976, it had pivoted to a blend of top 40 and oldies and was affiliated with the ABC Contemporary Network.

[9] Flagship Communications sold KBCM, which had become a country music station, to Park Communications for $675,000 in 1991; the deal, which paired the station with WNAX, was required because of Flagship's concurrent purchase of KSUX in Winnebago, Nebraska.

[13] Though the format was successful in the Sioux City radio ratings and had no issues in attracting advertisers, financial considerations led KCLH to begin simulcasting WNAX's full service blend of news, farm information, and country music on August 21, 2000;[14] also carried were some sports programming and Bill Mack.

[9] By 2001, while still simulcasting WNAX in morning drive, WNAX-FM had moved to a full-time country music format the remainder of the day.

The subchannel is branded "99.9 & 104.5 The Outlaw" to reflect its simulcasts on translator stations K260BO (99.9 FM) in Yankton, South Dakota (which previously simulcast WNAX), and K283AG (104.5 FM) in Sioux City (which had previously served as a translator for WNAX-FM's primary programming).
