In 1997, Paxson Communications bought WOCD from Cornerstone, moved the station's offices from Scotia, New York to Guilderland, and made the station an outlet for the Infomall Television Network (inTV). The call sign was changed to WYPX on January 13, 1998; however, the new calls confused some people as there was a radio station with a similar call sign in the Albany market. WYPX became a charter station for the Pax TV network when it launched on August 31, 1998. WYPX also added a secondary affiliation with UPN on October 5, 1998, airing the network's programming in late night hours following Pax's primetime programming. WVBG-LP (channel 25), a low-power station in Albany, also joined UPN as a primary affiliate the same day; the affiliation deal with WYPX was made before the network agreed to affiliate with WVBG (as Albany had no UPN affiliate at the time, though area cable systems imported WSBK-TV from Boston). WYPX retained its secondary UPN affiliation despite WVBG's affiliation; however, UPN programming disappeared from channel 55 in 1999.
