 The KTKT studios and transmitter are both located in northwest Tucson; in addition to a standard analog transmission, KTKT is simulcast over low-power Tortolita translator K232FD (94.3 FM), and is available online.In December 1949, KTKT first signed on at 1490 AM.The station's construction permit was originally granted by the Federal Communications Commission (FCC) to Thomas J. Wallace, Sr., Tom Breneman, Sr., and Art Linkletter in 1948; the two "T's" in KTKT were for the two Toms, and the K was part of Linkletter's last name.
