Translator History Early Days of KGKB; move to Tyler The facility was first proposed on March 27, 1928, by E.M., C.T., and E.E. Wilson, d.b.a. the Eagle Broadcasting Company. An application for a construction permit was filed to operate at 1070 kHz, with 50 watts of power, from a transmission site at Fisher & 5th Street in Goldthwaite, Texas. KGKB received its first License to Cover on May 22, 1928. The facility was again modified and requested an amendment of the license on December 6, 1928, moving the transmission site to Brownwood and the broadcast studio location to Howard Payne College. An amendment was requested to move KGKB's operating channel to 1500 kHz on October 24, 1928, as well as to increase power to 100 watts. In January 1931, the Wilsons requested to move the facility a second time, this time relocating to East Texas and giving the region its first licensed aural service. A permit was granted for the move to Tyler on March 6, 1931, and officially signed on the air in Tyler on May 15, 1931, continuing to operate at 1500 kHz @ 100 watts unlimited hours, from the new transmission site at the Tyler Commercial College. This facility is considered the oldest continuously licensed operation in East Texas, preceding both KOCA in Kilgore (1936), and KFRO in Longview (1935). The KGKB license was transferred from Eagle Broadcasting Company to East Texas Broadcasting Company on January 29, 1932. On November 10, 1936, KGKB was authorized to increase daytime power to 250 watts, while nighttime operations remained at 100 watts. Three years later, on October 3, 1939, KGKB gained authorization to use 250 watts unlimited hours. On February 13, 1940, the Commission revoked the license of KGKB, effective at 3:00 AM, March 1, 1940. East Texas Broadcasting Company immediately filed a request for a hearing with the Commission, which was granted on February 27, 1940. KGKB was allowed to continue operations during this period, and was federally mandated to change the operating channel from 1500 kHz to the current 1490 kHz, using the same 250 watt power level, as
