KBKF-LD

KBKF-LD is a low-power television station licensed to San Jose, California, and owned by Venture Technologies Group. Although its formal regulatory identity is that of a television station, its channel assignment gives it an unusual dual role in the broadcasting market. The station's channel 6 transmission can be received by many conventional FM radios at approximately 87.7 MHz, allowing KBKF-LD to function in practice as an FM audio outlet while also transmitting a digital television signal. The station began as KBKF-LP, an analog low-power television operation. Under the analog North American television standard, channel 6 placed its audio carrier at 87.75 MHz, close enough to the 87.7 MHz position on the FM dial to be received by ordinary FM receivers. This technical characteristic made channel 6 stations attractive for operators seeking to deliver radio-like programming without holding a conventional FM radio license. KBKF-LP used that capability to reach listeners in and around San Jose. The station became particularly significant during the transition away from analog low-power television. The Federal Communications Commission required low-power television stations to move from analog transmission to digital operation by July 13, 2021. Venture Technologies developed and tested a transmission arrangement that combined an ATSC 3.0 digital television signal with an analog FM audio component. KBKF-LD began dual digital-television and analog-FM transmissions in February 2021, making it a practical test site for the approach. The arrangement allowed the station to preserve its 87.7 MHz audio service while introducing a digital television feed. On June 10, 2021, the FCC granted the station a six-month Special Temporary Authority to continue the analog FM component at 87.75 MHz while the regulatory and technical issues surrounding the hybrid operation were evaluated. In July 2023, the FCC's Report and Order addressing so-called FM6 stations included KBKF-LD among 13 stations permitted to continue an FM radio broadcast as an ancillary or supplementary service. This decision recognized the unusual operating model while retaining the stations' primary status as television facilities. KBKF-LD has carried several audio and television programming arrangements. It previously transmitted Air1 worship music on its FM-compatible audio service, while its digital television feed carried programming associated with U Channel on digital channel 6.2. On April 13, 2025, the audio format changed to Bollywood music under the brand Suno 87.7. The change broadened the station's cultural and musical orientation and replaced the earlier Air1 format. The station's current identity is therefore best understood as a hybrid broadcast operation: a regulated low-power television station, an ATSC 3.0 experimental and digital outlet, and an FM-receivable audio service aimed at the San Jose market.

KBKF-LD originated as KBKF-LP, an analog low-power television station serving San Jose, California. Its importance has always rested partly on the technical properties of television channel 6. In the analog television system, channel 6's audio carrier was located at 87.75 MHz, a frequency close to the lower edge of the commercial FM band. As a result, listeners with ordinary FM receivers could hear the station's audio at approximately 87.7 MHz. Although the facility was licensed as a television station, this made its audio service functionally similar to an FM radio station for many listeners. The analog channel 6 model faced a major challenge when the FCC established July 13, 2021, as the deadline for low-power television stations to complete the transition from analog to digital transmission. A conventional digital conversion would have eliminated the analog audio carrier that made channel 6 stations receivable on FM radios. Venture Technologies Group therefore pursued a hybrid technical solution intended to preserve the FM-compatible audio service while adding digital television transmission. KBKF-LD became a test site for a version of ATSC 3.0 that could coexist with an analog FM audio component. In February 2021, the station began dual transmissions consisting of a digital television signal and an analog FM service. The arrangement allowed KBKF-LD to operate as a digital low-power television station while continuing to reach FM receivers near 87.7 MHz. The FCC subsequently granted Special Temporary Authority on June 10, 2021, permitting the station to continue its analog FM broadcasts at 87.75 MHz for six months. The station's hybrid operation formed part of a broader regulatory discussion about FM6 facilities. In a July 2023 Report and Order, the FCC included KBKF-LD among 13 channel 6 television stations allowed to continue an FM radio broadcast as an ancillary or supplementary service. The decision preserved the unusual combination of television licensing and FM-receivable audio while treating the FM operation as secondary to the station's television authorization. Programming on the station has changed over time. KBKF-LD previously carried Air1 worship music on its FM-compatible audio service. Its digital television operation has included a U Channel feed on digital channel 6.2. On April 13, 2025, the audio service moved to Bollywood music under the Suno 87.7 identity, replacing Air1. The change represented a format and branding transition rather than a change in the station's underlying license or ownership. KBKF-LD remains a San Jose low-power television station whose distinctive market role derives from the combination of ATSC 3.0 television transmission and an FM-compatible audio signal.
