In mid-1974 Riverside Church looked to cut its losses and sell WRVR, but with a preferred condition that the station's jazz format be preserved. At the same time, classical music-formatted WNCN (104.3 FM, now sister station WAXQ) was in the process of a controversial format change to Album oriented rock, with new call letters WQIV. A group of WNCN audience members formed the non-profit WNCN Listeners Guild and attempted to block the station's then-owner, Starr Broadcasting, from making the format switch. After their efforts failed, the WNCN Listeners Guild partnered with GAF Corporation and briefly entered negotiations with Riverside Church to purchase WRVR and switch its programming to classical. The rock format on 104.3 FM would last less than a year, as GAF announced it would purchase WQIV in July 1975 and restore 104.3 FM to its former call sign and programming.
