From looking around the internet recently, I have the idea that Kwessell spent some years at WCBM in Baltimore, and could well be retired in that area now. I recall him as taking positions that were extremely conservative, but that he was often very funny.
I have the idea that Dr. Frank Heninger might be retired also, perhaps somewhere warm. IIRC correctly, he was a UD professor that did a show that started around 6pm only during summer when the days were longer. There seem to be positive internet mentions of him as a professor, none mentioning his radio gig.
During the time I listened, Dick Norman was one of the hosts. He later went to WCKY in Cincinnati, then to WFLA, then quit WFLA upon learning that Jacor was buying it, returning to WCKY for something like a week, then returned to WFLA, either because someone convinced him that Jacor wasn't so bad, or that their lawyers were really bad. Then I believe he died in a car wreck there.
I'm thinking Brad Clay was the afternoon guy. I remembered him and Heninger being liberal, Kwessell being conservative, and Norman being moderate. At WCKY I thought he was basically conservative with some moderate mixed in; perhaps that's how he really was at WAVI. I wondered if the station had been deliberately set up to have an overall balanced set of hosts.
I remember them having two pretty good news anchors, Dave Harris who later worked at an FM station or two in Dayton, and Brenda Hart, who later worked at WKRC.
For some reason I remember their address as being 1414 Cincinnati Street. I don't know why I would remember that, unless they mentioned it on the air a lot for some reason. I remember them mentioning Bud Crowl quite a bit, WDAO not so much, though I knew they were co-owned. (That was a great sounding station on the occasions I listened to it.)
It seems to me they referred to their hosts as "talkmasters". They also had a good ID package including "People Power, W-A-V-I, Dayton." (Musical notes cgdf, edcfdg, ga)
At least as I remember it, that was amazing station, especially for a 1000 Watt daytimer. I listened in Cincinnati, and there was nothing here to compare with it at the time. In most cities, there's nothing to compare with it now.
