It signed on in 1976 from a combined studio and tower site north of the bay north of Corpus Christi and east of Sinton, Texas. Facilities were the same as now a 100,000 watt signal from a 410 foot above average terrain antenna. The studio site had on air studios, a bathroom, and the transmitter room. The first main transmitter was a Collins 831-G1. Most recently, the station switched to the active rock panel per Mediabase.
The 101.3 frequency had been used previously by KTOD-FM and by KMIO.
KNCN was known as C-101 and went on the air with a rock format. In later years, sales offices were established in the business center of CCT. They were once in the "600 Building" downtown, and later had their own building on Leopard street. Early on the station received permission from the FCC to identify as a Sinton-Taft station. A bit later they changed that to a Sinton-Corpus Christi identifier.
The station was founded by local owners. It was sold to Tippie Communications (whose shareholders had been involved with KHFI-AM-FM-TV in Austin, with Rollins/Terminix, and by the eighties with KVLY-FM in Edinburg, TX and an FM in the Colorado Springs, CO area.

Morning Shows included Greg (now deceased) and LJ 80's, Ray Lytle and Jon Lamb (89,90), Tim and Rex Two Guys in the Morning (91,92), Rex has been with the station since 91 and is still in the morning slot. Hannah Storm of ESPN had a brief stint as a C-101 DJ in the early 80s. The station was purchased by a company that has now been rolled up into Clear Channel Communications.
