a part of the NARBA reallocation. KGKB officially moved to 1490 on March 24, 1941. East Texas Broadcasting would ultimately be victorious in the license revocation hearing, resulting in the Commission vacating the Revocation Order on April 2, 1941, and fully licensing KGKB at its new operating channel of 1490 kHz, 250 watts unlimited. On October 9, 1944, East Texas Broadcasting would procure new stewardship as James G. & Minnie B. Ulmer acquired controlling interest in the corporation, through a purchase of stock from majority partner J.G. Kretsinger. The Voluntary license transfer for KGKB was granted by the Commission on May 22, 1945, and took effect on May 30. The Ulmers would own KGKB for just over five years, requesting a voluntary assignment of the license to Lucille Buford on October 18, 1950. The request was granted by the Commission 10 days later, with Buford Broadcasting assuming control of the license on October 28. Buford Broadcasting also owned and operated television station KLTV in Tyler, as the first channel to sign on in Tyler-Longview. Several changes to the 1490 facility accompanied the new ownership, including operating the transmission site remotely from a new studio location at Kilgore Highway and Farm to Market Road 1803, requested on June 1, 1954.

The license transfer was granted on July 1, 1957. Buford would go on to launch Tyler's first Top 40 format on 1330 KDOK, bringing Tyler into the new era of "Rock n' Roll" music, attracting a large audience, and topping the ratings in Tyler for the better part of the next few years. Litteral Enterprises would only briefly own KGKB, selling the facility to Oil Center Broadcasting Company on June 15, 1959. Oil Center Broadcasting would re-sell KGKB to O'Connor Broadcasting in October of the same year. On March 21, 1960, Harry O'Connor would request to move the control point and studios for KGKB from the Kilgore Highway location to 116 South Broadway in Tyler, which was granted on April 8. O'Connor's stewardship of KGKB would ultimately prove to be a literal dark period for the
