From August 1, 1955 until 1960 it was called KPOP. From June 29, 1960 until 1976, it was called KGBS. On September 27, 1976 the station's call sign was changed to the current KTNQ, originally billed as "The New Ten Q."
In its early years, between January 3, 1929 and December 31, 1931, KFVD broadcast from offices and towers on the Hal Roach Studios' lot.. From 1937 to 1939, Woody Guthrie broadcast regular shows from the station, then run by Frank Burke Sr. and his son Frank Burke Jr. First he accompanied his Cousin Leon "Oklahoma Jack" Guthrie, later with Maxine "Lefty Lou" Chrissman. The Woody and Lefty Lou-Show soon became the most popular on the station. When Chrissman resigned due to health reasons, Guthrie continued for another year as The Lone Wolf until he was sacked for his unrelenting support for the Soviet Union even after they invaded Poland.
