Listened to Joe Donvan a lot living in Western NY in the 1990's. Also, the weekend evening music blocks. I recall hearing Terry Meiner's show during the winters with early sunsets and his jetson's theme intro to his show. Would wake up to Wayne Perky pre sunrise some mornings. Jack Fox did some weekend evening's and he was a fantastic DJ.
The station sounded fantastic overall to me - was really well put together and I listened a lot especially after WOWO bit the dust leaving WHAS the last big 50KW doing this type of format. Also recall Doug McKelvin, Joe Elliot and Milton Metz among others.
Yes, they sounded great in AM Stereo as well even via skywave. They were the first AM I ever heard in stereo. Sitting in my friend's 1980's Trans Am with a factory AM stereo tuner, I flipped to WHAS and Let It Ride by BTO came blasting out of the speakers. After that I made getting an AM Stereo a receiver high priority.
