The station went on air in 1938 on a local channel. Its former callsign KRBC was made up of the first letters of Reporter Broadcasting Company (RBC). RBC was an affiliate of the Abilene Reporter News newspaper. In late 1940s, station changed channels to 1470 with 5,000 watts days and 1,000 watts at night using a three tower directional antenna located north of Abilene. Studios were in a downtown hotel for many years. Station later moved in with Channel 9 KRBC-TV on south 14th street.
KRBC was spun off to some of its shareholders (Members of the Fox family) in 1986. They later acquired an FM in nearby Merkel, Tx which is today's 102.7. Scion Shane Fox went on to found Maxagrid a maker of Ratings analysis software. He later owned many central Texas stations.
