KZNO-LD: The Evolution of a Big Bear Lake Broadcast Station
The landscape of local broadcasting is often defined by small, community-focused stations that adapt to changing technology and regulations. One such example is KZNO-LD, a station based in Big Bear Lake that has transitioned from a local public-access style outlet to a modern digital broadcaster with a unique radio presence.
The Early Years and Community Roots
Founded on August 7, 1996, the station began its journey as translator K06MU. In its early stages, it served the Big Bear Valley community, offering programming that mirrored a public-access cable channel. Its content focused heavily on local news, public affairs, and travel programs produced by the residents of the valley. To increase accessibility, the station was also available to Charter Cable subscribers on channel 6.

Ownership Shifts and Technical Transitions
For many years, the station was managed by Bear Valley Broadcasting. However, in 2016, ownership transferred to Venture Technologies. This new owner also held KSFV-CA (now KSFV-CD), a station that operated on analog channel 6 as a radio station. KSFV-CD currently shares transmitting facilities with the Ontario-licensed KPOM-CD on Mount Harvard, a peak located adjacent to Mount Wilson in Los Angeles County.
The Analog-to-Digital Shift
As a Low-Power Television (LPTV) station, KZNO-LP followed a different regulatory path than full-power stations. While full-power stations in the United States were required to switch to digital signals by June 12, 2009, LPTV stations were not bound by this specific deadline.
This allowed KZNO-LP to continue analog transmissions for over a decade longer. A notable characteristic of this period was that the station's audio could be picked up by local radio receivers on 87.7 FM, because TV channel 6 operates within the 82–88 MHz frequency range.
The Move to Digital and the FM6 Designation
The transition to digital finally arrived in 2021. KZNO-LP ceased its analog transmissions on July 9, 2021, just days before the Federal Communications Commission (FCC) deadline of July 13, 2021. On July 15, 2021, the station was officially licensed for digital operation and updated its call sign to KZNO-LD.
Despite the digital shift, the station sought to maintain its radio presence. On July 27, 2021, the FCC granted a six-month special temporary authority to resume audio transmissions on 87.7 FM. This effort culminated on July 20, 2023, when an FCC "Report and Order" designated the station as one of 13 "FM6" stations. This status allows the station to continue operating an FM radio broadcast as an ancillary or supplementary service.
