KGNC (710 kHz) is an AM radio broadcast station in Amarillo, Texas, United States with a news/talk format.
At night, the station has a more restrictive directional antenna, that sends most of its signal north and south, and can sometimes be heard as far west as Tucson, Arizona.
KGNC was formed in 1935, when the Amarillo Globe-News Publishing Company purchased and consolidated two existing stations, WDAG and KGRS.
[3] Because there was only one available "entertainment" wavelength, stations in a given region had to develop timesharing agreements, in order to assign exclusive timeslots for broadcasting on 360 meters.
Initially call letters beginning with "W" were generally assigned to stations east of an irregular line formed by the western state borders from North Dakota south to Texas, with calls beginning with "K" going only to stations in states west of that line.
In January 1923 the Mississippi River was established as the new boundary, thus after this date Texas stations generally received call letters starting with "K" instead of "W".
[4] Amarillo's first broadcasting station was WDAG, licensed to J. Laurance Martin at 605 East Fourth Street on May 16, 1922, for operation on 360 meters.
[13] Effective November 11, 1928, with the implementation of the Federal Radio Commission's General Order 40, both WDAG and KGRS were moved to 1410 kHz, on a timesharing basis.
[23] In 1994, the Federal Communications Commission found the Equal Employment Opportunity policies of KGNC and KGNC-FM to be deficient.
