The station began operations as K64DT on September 28, 1992. The station increased its power, changing its callsign to KDTL-LP in 2004 after being sold to Word of God Fellowship, the commercial license arm of the Daystar Television Network, to broadcast Daystar's programming. The station converted to digital operations at the end of 2011, and changed its callsign to KDTL-LD on January 5, 2012.
On May 9, 2022, it was announced that Daystar parent company Word of God Fellowship would sell KDTL-LD to Atlanta-based Gray Television, which had acquired KMOV the year previous after purchasing Meredith's broadcast division and its stations, for $1 million;[2] the sale was completed on July 1.[3]
Following the consummation of the sale to Gray, the station dropped affiliation with Daystar, as its programming is carried by full-power station WPXS (channel 13) since it purchased the station in 2010, and also duplicated in the inner core of St. Louis on in-market repeater KUMO-LD (channel 51). The station initially aired an automated feed of current weather conditions, forecasts and observations from KMOV's weather computers in high definition on its second subchannel (mapped to channel 4.7, using KMOV's channel position), while its main channel (mapped to 4.6) carried Corner Store TV, an all-paid programming network, in a transition period while Gray acquired programming to place on it with its former affiliated network Circle winding down at the end of 2023.
