As far as I know, Mr. Miller still owns the stations. He is also the morning host on both AM and FM as they simulcast during that time.
WDNY was indeed very well programmed "back in the day". I recall they had a sort of full service AC format that was live and local from 6a-7p, then they ran Bruce Williams' TalkNet from 7-11p. Overnights, they ran Larry King and whatever else came down the Mutual network feed during the wea hours.
In 1991, things changed. At first, the live/local programming continued during the day. At 7p, they split AM and FM (the FM calls were WACZ at that time). The AM carried TalkNet, while the local programming was extended on FM thru 11p. The Mutual programming was dropped, and both stations signed off at 11 (I recall the jock who signed the stations off would always play "Sounds of Silence" before running the sign off cart).
This setup was in place for a couple of months. Then, in the spring of that year, the satellite service was implamented. It was the AC service from Westwood One/Unistar, I think. I took a tour of the station around that time, and most of the former jocks were still kept on as board ops for the new service. Of course, they would eventually be replaced by out right automation.
In the mid 90s, they split the stations for most of the day, save for morning drive. The AM went with country, FM stayed the same. The country gave way to standards a couple years later. I later found out one of the reasons for this was the problems they had receiving the satellite signal for the country format.
As I stated earlier, I am happy there are still some local elements in the programming. However, I hope the new owner will not only retain those local elements, but perhaps expand on them. Of course, one has to be realistic, though.
It will be interesting to see what becomes of the AM signal. It's no secret that the standards format, such as it is these days, is dying. I predict that will almost certainly give way to some form of spoken word programming. (ESPN 1400, anyone?)
