During the analog era, WSTR-TV operated a translator station in Dayton, W66AQ, on channel 66. This translator signed on in May 1981, rebroadcasting then-WBTI's ON TV service and other programming. When WSTR-TV subsequently gained network affiliations, Dayton had local affiliates of those networks as well. When WSTR-TV was a UPN affiliate, the network had a secondary affiliation with Dayton's WRGT-TV. When WSTR-TV was a WB affiliate, that network aired in Dayton first on WUCT-LP (now WRCX-LP), then on WBDT. When WSTR-TV became a MyNetworkTV affiliate, Dayton had its own affiliation on WRGT-TV's second digital subchannel, WRGT-DT2 ("My TV Dayton"). FCC filings indicate that W66AQ was silent by sometime in 2007. In 2009, after the digital television transition, Sinclair used the W66AQ license to broadcast a low-power analog signal in Dayton on channel 22, repeating its "My TV Dayton" programming. On June 30, 2010, W66AQ's call letters were changed to W22DE. Cincinnati's WCPO-TV moved its digital operations to channel 22 on December 8, 2010 (according to RabbitEars, this knocked W22DE off the air; however, W22DE filed for a license renewal with the FCC on June 3, 2013).
