I listened to a few Monday Morning sign ons of WCFL, from it's transmitter in "Downers Grove, Illinois". Also a few pattern changes over the years.
What DXer from that era does not remember this on 1000 on Monday mornings:

My informal survey of my high school peer group in a small town in Western Ohio was that WLS won the night. I seemed to be the only person who knew of WABC's existence, though arguably WABC had a better signal due to WLS's skywave/groundwave cancellation issue. We had a booming signal from CKLW during the daytime, and top 40 from WMEE in Fort Wayne, both of which we lost at night. If you only had AM in the car, it was WOWO or WLS at night
Could you hear WLS at all during the day in Western Ohio? I'm guessing it might have been squeezed by the 880 in Columbus.
Here are the earliest Chicago ARBs I have:
Fall 1970
WGN—12.9
WLS—11.8
WAIT—8.3
WCFL—8.2
WBBM-7.7
When Michael DelGiorno interviewed DJs from WIND and WLS recently, including his father Bob, they were discussing how well WIND did in the ratings. I was surprised, but I realize that with 5 kW at 560 and the DA pattern, the signal was one of the best in the immediate Chicago area.

When Arbitron started measuring radio in 1965, Chicago was one of the first markets it surveyed. In the initial surveys, the top spot typically rotated among WGN, WIND and WLS.
MAY 1965
WGN - 17.6
WIND - 17.5
WLS - 14.9
SEP/OCT 1965
WIND - 16.1
WGN - 14.2
WLS - 14.0
JUNE 1966
WLS - 14.3
WIND - 14.0
WGN - 12.2
Prior to that, here are some Hooper surveys showing WLS' performance in the early 60s:
MARCH 1963
WLS - 18.3
WIND - 18.0
WGN - 14.7
OCTOBER 1962
WLS - 22.0
WIND - 15.3
WGN - 13.3
