KBKF-LD (channel 6) is a low-power television station in San Jose, California, United States.

Owned by Venture Technologies Group, it transmits from an antenna on Loma Prieta Peak.

Originally KBKF-LP, it initially transmitted as an analog TV station, taking advantage of the fact that the analog TV standard for channel 6 specifies the audio portion of the transmission as an FM signal centered on 87.75 MHz.

Faced with an approaching July 13, 2021, FCC deadline requiring all LPTV stations to convert from analog to digital transmissions,[2] Venture Technologies developed a version of the ATSC 3.0 digital TV standard that allows an analog FM audio subcarrier to coexist with the digital TV signal.
