Return to sports format
The sale to the religious group never followed through. Instead, the station returned to air on November 5, 2015, after being leased out to Markel Radio Group, operators of talkstl.com, which had already been leasing KXFN. TalkSTL programming was simulcast on both stations until December 2015, when KXFN went silent, with KFNS continuing to air TalkSTL programming. The station was sold to Markel Radio Group, effective February 22, 2016, for $300,000.
In September 2016, Markel leased the station's broadcast day to former KFNS host Tim McKernan and his company, InsideSTL Enterprises;[Station Sales Week Of 6/10]
, ''RadioInsight''. June 10, 2016. Retrieved September 23, 2019. McKernan had previously leased WGNU on weekdays. As a result, KFNS took over as St. Louis' CBS Sports Radio and Fox Sports radio affiliate. As part of the lease arrangement, the station's license was transferred to McKernan Radio Group, LLC, which was 75% owned by Markel and 25% owned by McKernan. In 2018, Randy Markel acquired total ownership under Markel Entertainment LLC. In November 2021, Markel sold all interests in KFNS to Zobrist Media LLC and it remains privately held under principal Dave Zobrist. Markel later cited the pandemic and the loss of sports content to cover as the reason for the sale, and noted in July 2024 he was interested in reacquiring the station since then.
On June 27, 2024, Barrett Sports Media reported that the station would shut down at the end of June. Zobrist clarified that the station would remain on the air, but that its local talk programming would cease as it shifted to a full-time Fox Sports Radio
