KTNC-TV (channel 42) is a religious television station licensed to Concord, California, United States, serving the San Francisco Bay Area as an owned-and-operated station of Tri-State Christian Television (TCT). The station's transmitter, shared with KMTP-TV, KCNS, and KEMO-TV, is located atop Sutro Tower in San Francisco. History As an independent station The station first signed on the air on June 19, 1983, as KFCB, which was originally owned by First Century Broadcasting (later known as Family Christian Broadcasting)—from which the station's original call letters were taken. At that time, its president was Reverend Ronn Haus. A majority of the station's broadcast day was devoted to Christian programming, including its own in-house productions. The station's flagship program was called California Tonight (later retitled Coast to Coast), a Christian talk show with sermons, conversations with religious topics and musical guests. The program utilized an applause cart (audio tape cartridge) to give the viewers the impression that a studio audience was present during the tapings. Other programs seen on the station included The 700 Club, Dr. Robert Schuller's Hour of Power and various other local and national religious programs, usually of an evangelical nature. In its earliest years, KFCB supplemented the religious programs with secular shows such as Speed Racer, Dennis the Menace, The Donna Reed Show, Father Knows Best, The Mighty Hercules, Candid Camera, New Zoo Revue and other programs as well as CNN Headline News, for about six hours a day. Although the station aired secular programming and some commercials, KFCB's primary revenue source continued to come from viewer donations; commercial revenue was not significant. The few commercials that aired were primarily "direct response" spots and public service announcements. The station broadcast semi-annual telethons, in the manner of public television and radio stations. Christian children's programs included The Gospel Bill Show, Superbook and Davey and Goliath. From 1985 to 1986, the station phased out most of its secular shows, although a lineup of such programs remained on Saturday mornings until at least 1989. The secular shows were occasionally modified to meet the station's programming standards—for example, master control operators were instructed to cover up the "Hollywood Minute" feature during CNN Headline News broadcasts, and beer commercials were deleted from airings of the syndicated discussion program It's Your Business. During the fall of 1989, KFCB aired a schedule of Western Athletic Conference college football games. KFCB's studios were originally located at 5101
