In 1985, WDAV made plans to increase its signal from 20,000 to 100,000 watts using a directional antenna to prevent interference with WEPR. The station was also moving from a small space in the college's union building to a new building. The power boost, approved in August 1988 and completed in mid-1989, would increase the listening area from 1702 to 2402 square miles, with as many as 850,755 listeners. On October 1, 1988, WDAV began broadcasting 24 hours a day. That same month, the station became an affiliate of American Public Radio, with "Radio Kronos" and "High Performance with André Previn".
