History
The station was founded in 1933 by Clyde E. Palmer as a sister outlet to his Texarkana Gazette. It was Texarkana's first radio station. By approval of the Federal Communications Commission, station WDIX, Tupelo, Mississippi, was shut down, and operation of KCMC in Texarkana, Arkansas, was authorized. KCMC operated on 1420 kHz with 100 watts of power.

The station is an affiliate of the Dallas Cowboys radio network.

Disk jockey Barney Cannon (1955–2009), an authority on Country music who spent a quarter century with KWKH in Shreveport, once worked at KCMC.

On January 15, 2015, the then-KTFS changed formats to talk, branded as "Talk Radio 740".

On July 1, 2017, KTFS went silent. On November 28, 2017, KTFS's call sign was changed back to KCMC. A news release on the KTOY website said that KCMC could return to the air from a new facility at some time in the future.

On January 22, 2019, KCMC returned to the air with conservative talk, simulcasting KTFS-FM 107.1 Texarkana, AR.

In mid-October 2019, KCMC dropped its simulcast with KTFS-FM and changed its format to sports, branded as "107.9 The Fan".

740 AM is a Canadian clear-channel frequency, on which CFZM in Toronto, Ontario is the dominant Class A station. KCMC must reduce power during nighttime hours in order to protect the nighttime skywave signal of CFZM.
