KIOA

Its HD2 subchannel carries a Top 40 (CHR) format branded as "Hits 99.9", which is also heard on 250–watt FM translator station 99.9 K260AM in Des Moines.

[4] George Webber, who was the founder of the original KWDM (1150 AM, later KWKY), brought back his unique programming after having sold the AM station in 1959 to the 3M Corporation.

The schedule also included a weekday talk show, "Listen While You Work," hosted by his wife, Edith Dunham Webber, and Drake University and high school sports.

The studios were moved to the Mike Wilson building at 4111 Hubbell Avenue, on the east side of Des Moines.

A controversial talk show, the "Hawkeye Nightline," with Russ Lavine, aired Monday-Saturday nights, previously heard on KDMI (97.3 FM, now KHKI).

On Sunday nights, John Birch Society members Jim and Mary Parker hosted that three-hour slot.

Although Webber wanted to bring back the fine music format, he lacked the finances and was too far advanced in his years to make a go of it.

In March 1976, the station flipped back to Top 40, this time as "Magic 93"; with it, the call letters changed to KMGK.

This was the most successful format to date on the frequency, as the station pulled in good ratings through the late 70s and early 80s.

By the mid-80s, KMGK found itself fighting for market share as KRNQ, KCCQ, and KLYF began also playing hit music on FM radio.

"[13][14] Over time, KIOA-FM's listener base grew and the station became one of the most successful in the Des Moines area.

On July 31, 2007, Saga Communications announced that it would not be renewing the contract of longtime KIOA morning program co-host, Polly Carver-Kimm.

Carver-Kimm had been part of "Maxwell and Polly in the Morning," and had also been news director for Saga's other five Des Moines radio stations.
