1430 was Oldies about four years ago when still under the WRTH Calls as "Real Oldies 1430," before switching back to Standards, then to Country Classics as WIL-AM once again.
The playlist is pretty large, but they are playing a lot of obscure songs - if you want to see what they are playing, go to Yes.com, and look under WIL-AM. They are playing several poor re-recordings of songs, and it sounds pretty small market.
The owner of the station is Bob Romanik, a former Police Cheif of Washington Park, IL, and current owner of the Hollywood topless club also in Washington Park.
Studios are in a retail strip mall in Belleville, IL, shared with sister station 1510 AM WXOZ/Highland.
The Oldies format being heard on 1430 now, is the format from 1510, and 1510 has flipped to Classic Country as "Cool Country." WXOZ has an application to upgrade power to 5kW, which would cover the entire metro area, but still as a daytime only operation.
