satellite of WGKI reaching the Gaylord and Petoskey areas. (As mentioned above, unlike the other network affiliates in the market, the station was simply known as "Fox 33" and didn't include any of the other satellites and repeaters used in the branding; they were simply listed under the graphic on the legal ID.) When CBS affiliate WJBK-TV in Detroit switched its affiliation to Fox in December 1994 (which caused WGPR-TV to become the new CBS affiliate for Detroit), WGKI started using that station's resources. The move also disallowed rival WKBD from distributing Detroit Red Wings and Tigers games to WGKI. Knapp made a station promo explaining the situation between the three stations. When the Fox affiliation switch in Detroit was made, WGKI replaced WKBD on cable systems in Mid-Michigan and the Eastern Upper Peninsula. This was done so viewers without a local Fox station would maintain access to the network's programming. As a consequence, WGKI also expanded into parts of the Flint, Lansing, Grand Rapids, and Detroit markets via cable carriage. As a result, some cable viewers (especially in Bay City, Saginaw, and Michigan's Thumb area) found out that most of WGKI's programming, especially those from Fox, were being blacked out by request of the local affiliate. Soon after, many systems outside Northern Michigan and the Upper Peninsula dropped WGKI and/or brought back WKBD. On January 15, 1995, WGKI became a secondary affiliate of UPN. It aired the network's shows outside of prime time. WGKI continued to air UPN programming until 2006, when UPN merged with The WB to form The CW, at which point WGKI ended its affiliation. In 1999, the channel increased its ERP from 219 kW to 774 kW, significantly increasing its coverage area. In 2000, Knapp retired and sold his stations to Rockfleet Broadcasting for $12 million. Part of the deal called for both channels to change call letters. WGKI became WFQX-TV and WGKU became WFVX. In 2003, Rockfleet moved the WFVX call sign to a low-power station it had acquired in Bangor, Maine, and changed the Vanderbilt station's call letters to WFUP. On February 10, 2007, WFQX upgraded its digital signal on UHF channel 47 (from a transmitter shared with WGTU east of Kalkaska) to begin airing all Fox programming in high definition for over-the-air viewers. (Prior to then, the station offered a low-power digital and HDTV signal near its studios southeast of Cadillac.) WFQX
