KRNT

[4] In 1926, an adverse legal decision briefly eliminated the ability of the U.S. government to assign station frequencies and powers, and as of December 31, 1926, KSO was reported to now be at 740 kHz.

[7] The next year government control was re-established with the formation of the Federal Radio Commission (FRC), and on July 1, 1927, KSO was reassigned to 1320 kHz.

[13] In August 1941, the Federal Communications Commission (FCC) began implementation of a "duopoly" rule, which restricted licensees from operating more than one radio station in a given market.

[16] For years, KRNT carried an adult standards format, supplemented by sports programming (most notably the Chicago Cubs and Drake University athletics).

[17] In April 2022, station owner Saga Communications requested a waiver to change the call sign back to the original KSO.
