The SCA was part of the reason that Roy H. Park, owner of Park Broadcasting, purchased the station in late 1975. At the time, Park was one of the largest broadcast companies in the U.S., with many of its stations also airing beautiful music, including WPAT-AM-FM in the New York metropolitan area. KEZX increased its power in the spring of 1977 to 100,000 watts. Under Park, the station used the Bellevue-based BPI syndicated service, then, beginning in the Spring of 1976, the "FM 100 Plan" from WLOO in Chicago; locally originated programming would return in 1980.
