In Bakersfield, KBFX 58 (FOX), which is considered a low power station, is on their sister station's full power signal , KBAK 29(CBS) Virtual channel 33, on the sub channel 58.2 which is a 480i wide screen format, while they broadcast full 1080pHD on their low power station, virtual channel 29 at 58.1, the reason is to extend KBFX signal to the high desert, Mohave, Lancaster, Barstow, Palmdale, and Ridgecrest, originally 58.2 was the ONLY signal, until recently 58.1 was added.
The reason KBFX cant be Full power HD is because of KMPH 26, they have a hugh signal from just north of Bakersfield to Merced, and originally KBFX used to be a Sister station to KMPH, when they were owned by Harry Pappas, and they simulcasted most programming from KMPH.
All other Fresno stations (CBS, NBC, ABC, My, CW, Univision, Telemundo) TL are located at Meadow Lakes much further north than KMPH 26, and have no (Good) signal in Kern County.
