KCRC (1390 kHz, "CTB Sports 1640 AM/1390 AM") is a sports AM radio station serving the Enid, Oklahoma, area and is owned by Chisholm Trail Broadcasting, Co. The studios are located in Enid at 316 E. Willow.

History The station was first licensed on August 19, 1926, under the call sign KGCB, to the Wallace Radio Institute in Oklahoma City."New Stations", Radio Service Bulletin, August 31, 1926, page 3. In early 1929 the station was bought by the Champlin Refining Company, which changed the call sign to KCRC."Alterations and Corrections", Radio Service Bulletin, February 28, 1929, page 12. The station was a charter member of the Oklahoma Network when it was formed in 1937.

Expanded Band assignment On March 17, 1997, the Federal Communications Commission (FCC) announced that eighty-eight stations had been given permission to move to newly available "Expanded Band" transmitting frequencies, ranging from 1610 to 1700 kHz, with KCRC authorized to move from 1390 to 1640 kHz."FCC Public Notice: Mass Media Bureau Announces Revised AM Expanded Band Allotment Plan and Filing Window for Eligible Stations" (FCC DA 97-537), March 17, 1997. An application for the new expanded band station, also licensed to Enid, was filed in 1997, which was issued a construction permit the next year, and after a series of call letter changes became KZLS.Call Sign History for 1640 kHz (Facility ID: 87168)

The FCC's initial policy was that both the original station and its expanded band counterpart could operate simultaneously for up to five years, after which owners would have to turn in one of the two licenses, depending on whether they preferred the new assignment or elected to remain on the original frequency. However, this deadline has been extended multiple times, and both stations have remained authorized. One restriction is that the FCC has generally required paired original and expanded band stations to remain under common ownership."In re: WHLY(AM), South Bend, Indiana" (FCC DA 13-600, released April 3, 2013)"Re: WDDD (AM) Application for Consent to Assignment of AM Broadcast Station License" (August 23, 2010, correspondence from Peter H. Doyle, Chief, FCC Audio Division, Media Bureau. Reference Number 1800B3-TSN)
