KTDK was a radio station with studios located in Sanger, Texas, United States, formerly under ownership of Cumulus Media.

The station was granted a construction permit in 1988 as KWSM in Sherman, co-owned with KTXO (1500 AM, now KJIM); it began broadcasting in December 1989.

A year later, Susquehanna Radio Corporation acquired the station, changed callsigns to KXZN and simulcast KKZN "93.3 The Zone" (classic rock).

Therefore, the FCC determined that the sale to Whitley was a straw purchase in which Cumulus would remain the de facto owner of KTDK.

KTCG of Sanger was granted a license on October 13, 2022, to transmit with an effective radiated power of 6,200 Watts from a radiation center 181 meters above ground at 33-28-47.7 N 97-3-23.5 W. KTCG is owned by Radio Brands, Inc. As of April 2016, the 104.1 frequency has been utilized by a few low-powered stations such as KEJC-LP in Dallas, KYRE-LP in Mansfield, and KLEJ-LP in Fort Worth; all broadcasting at 100 watts.
