Larry White discusses the later run WBUF made at WBEN's crown, which was a serious challenge indeed...and I don't doubt that y'all gave WBEN a real fight because 'BUF was a fine sounding station in the middle and late 80s. IIRC you had an on-air lineup that included yourself, Stan Roberts, and was Steve Mitchell there too? Anyway, it sounded great.
I left the market, and radio, in '81 so I missed a lot of the action, although my business still took me to Buffalo from time to time and I still did a lot of listening with more than a casual interest. Buffalo was blessed with some really good radio through the 80s. There was WBEN, WKBW (until it started really going downhill after CapCities/ABC dumped it), WGR, WBUF, 97Rock, and then Q102 started coming on strong. There were a lot more important players in the game by 1985. But I'm old enough to remember the late 70s when those of us working in one of the big 3 on AM (which at one point divided about half the audience among us) were worrying so much about each other, we didn't see those big FM signals sneaking up on us.
