40 Miles NW of downtown Chicago...
Day WISN Milwaukee with a good signal. 50kw from a 9 tower array near Union Grove, WI. About 38 miles NE of me. As David and others have noted, WISN moved from 1150 using a very tight array from a 9-tower site to shoehorn it in between two other high power flamethrowers in Minneapolis and Detroit. Major lobe is to the north. Minor lobes to the south and west. Tight nulls to the northwest, southwest and east. (it barely makes it across Lake Michigan.)
Night: WISN powers down to 10kw and tightens the pattern. The result is that it completly vanishes. WBBR is in more often than night, KWKH once in a while. WDFN less likely. I/ve heard CKWH a handful of times, but not recently. I heard Minneapolis (as WDGY) a couple of times when I was still in high school on daytime skywave, but not since,
