KCOH (1230 AM) is a radio station in Houston, Texas. The station brand is "The One Twelve Thirty" and broadcast religious music, sports, local talk and associated programming. The station is currently under a LMA to the Dunn organization that provides the programming. Under Liberman's programming control, it was "Radio Ranchito" and "La Ranchera", both ultilizing a Regional Mexican music format. The radio station began in 1948 when KTHT (now KBME) vacated this frequency for a stronger signal at 790 kHz. Under the KNUZ callsign, it was a Top40 formatted station through the 1960s, competing with KILT (AM) but eventually Houston outgrew 1230's signal coverage and KILT won the battle in the early 70s.
