KOKI-TV
KOKI-TV, virtual channel 23 (UHF digital channel 22), is a Fox-affiliated television station licensed to Tulsa, Oklahoma, United States. The station is owned by the Cox Media Group subsidiary of Cox Enterprises, as part of a duopoly with MyNetworkTV-affiliate KMYT-TV (channel 41); KOKI and KMYT are, in turn, co-owned with local radio stations KRMG (740 AM and 102.3 FM), KRAV-FM (96.5), KWEN (95.5 FM) and KJSR (103.3 FM), as well as local cable television provider Cox Communications.
KOCO-TV
KOCO-TV began transmitting a digital television signal on VHF channel 7 on November 1, 2002. The station discontinued regular programming on its analog signal, over VHF channel 5, on June 12, 2009, as part of the federally mandated transitioned from analog to digital television. The station's digital signal remained on its pre-transition VHF channel 7, using PSIP to display KOCO-TV's virtual channel as 5 (corresponding to its analog channel) on digital television receivers. After the switchover, the marginal reductions to the broadcast radius of KOCO's digital signal created some reception gaps in parts of southern and north-central Oklahoma that previously, at best, received Grade B coverage from its analog signal. In May 2010, the station installed a new digital transmitter antenna and dish on the Britton Road tower to help extend KOCO's signal reception to the affected areas.
