Apparently the operator(s) of 98.5 were previously busted in 2012 and 2001. Always on 98.5. I predict they’ll come back, on 98.5 again, and right about that time Cumulus will light up their new translator on 98.5.
EDIT: Apparently one of the recent incarnations of “KHAC” started out on 87.5. http://www.eugeneweekly.com/2011/12/08/news.html#s3
Why can’t they admit they just want to do it for the thrill of giving the evil FCC the finger? 😉
