On January 11, 1989, the Roman Catholic Diocese of Corpus Christi started K47DF "KDF", which initially broadcast a family-oriented program lineup that also included religious shows.

[6] The next year, KDF affiliated with Fox, which had only been available via either Foxnet or San Antonio's KRRT on the cable systems in the Coastal Bend region.

[7] Paloma announced the sale of its stations in January 1997 to Miramar Broadcasting Company, in which one of the stockholders was KRIS owner T. Frank Smith.

[11] On January 16, 2008, it was announced that KDF would lose its Fox affiliation in favor of new higher-powered KUQI, which began airing the network's programming starting on February 4, 2008, the day after Super Bowl XLII.

On February 20, 2013, the FCC cancelled the station's license, citing operating on an out-of-core channel (52 to 69) and not having built a replacement facility after the December 31, 2011, deadline to cease broadcasting in that band.

In November 1993, KDF started a 9 p.m. local newscast, The Nine O'Clock News, which was hosted by former KRIS anchor Jay Ricci; originally 15 minutes in length, the program expanded to a full half-hour in January 1994.
