Channel 43 became a PBS member station on August 15, 1991—becoming the city's second non-commercial educational station, after OETA flagship station KETA-TV (channel 13)—while much of its syndication inventory and Fox affiliation migrated to channel 25. Thirty employees (among them, KAUT general manager Harlan Reams, who took over that same position at KOKH), and other equipment and intellectual property held by channel 43, were also included in the transfer. The station's programming conversion was part of a national education demonstration initiative formed between OETA's Board of Directors, the OETA Foundation Board of Trustees, and Heritage Media; PBS senior vice president for education services Sandy Welch, and management with the Children's Television Workshop collaborated with the consortium in the development of the station's new format, which OETA and PBS intended to use as a model for instructional and educational programming on a national level. Under OETA ownership, Channel 43 reduced its schedule to 14 hours per day initially (from 7:00 a.m. to 11:00 p.m.), mirroring the OETA network's programming hours on Sunday through Thursdays during that timeframe. To fill the vacated programming time, cable providers throughout central and western Oklahoma designated KTLC's assigned channel slot as a timeshare feed to carry other cable networks. (The station's channel slot on Cox Cable's Oklahoma City area system—which carried QVC on channel 13 during KTLC's off-time from January 1992 until channel 43 dismembered from PBS—suffered from direct pickup interference by, ironically, the VHF analog signal of sister station KETA-TV, an issue that Cox's move of KAUT/KTLC to channel 13 in January 1987 was claimed to address. These issues eventually resulted in Cox moving KAUT's basic tier slot from channel 13 to channel 16 in 2007.)
