KMHB was the cable-only affiliate of The CW network in the Rio Grande Valley. It was carried on Time Warner Cable channel 53. The station was part of The CW Plus, and as it was a cable-only station, the use of the "KMHB" call letters was done in a fictional manner as cable-only affiliates of broadcast networks are not required to operate under an FCC station license. However, after more than a year, Time Warner Cable replaced KMHB with a new terrestrial CW affiliate, KSFE-LP, on November 7, 2007.
