Lincoln County Broadcasters was granted a construction permit for a new station on 1230 kHz in Libby on August 17, 1950.

Principals in the company included Oliver G. and Mary Elizabeth Coburn, co-owners of Coburn Electronics; Rogan Jones, president of KVOS in Bellingham and KPQ in Wenatchee, Washington; and James W. Wallace, vice president and general manager of KPQ.

[5] By 1954, the Coburns shared ownership of the station with William F. and Agnes Hafferman;[6] that April, KLCB became the ninth affiliate of the West Radio network, which also included KSPO in Spokane, Washington; KRLC in Lewiston, Idaho; and KSPT in Sandpoint, Idaho.

[7] In 1957, Lincoln County Broadcasters sold KLCB to Frank Reardon, who had stakes in KBOW in Butte and KGEZ in Kalispell, for $19,000.

[16] By 1975, it was a middle of the road station carrying the ABC Information Network;[17] by 1978, KLCB's playlist was a blend of soft adult contemporary and country music.

[14] KLCB and KTNY were closed by Lincoln County Broadcasters on January 1, 2025; their licenses were returned to the Federal Communications Commission (FCC).
