KMPH-TV's focus is on the San Joaquin Valley and Central California. KMPH-TV's signal is receivable as far way as the Bakersfield area; however, local Fox affiliate and sister station KBFX-CD (itself once a KMPH repeater) exclusively carried on cable providers in the Bakersfield market. KMPH's airwaves extend northward to Mariposa and Merced, and the southern Sierra Nevada, and sometimes can be received in Monterey County for those who live just north of King City. KMPH has been received over-air sometimes in eastern Kern County (Ridgecrest) and San Luis Obispo.
