40 miles northwest of downtown Chicago....
Days: WYLL with a good signal. But not quite as good as the other Chicago 50kw blowtorches.
Nights: WYLL still good, but from a nighttime site about 20 miles south from the daytime (and original) site. Also a tighter pattern protecting KSL. SC calculated a few years back that around 31kw is effectively what WYLL sends my way at night. The net result of the more distant location and tighter pattern is, while the signal is still good, I can usually hear unidentifiable stuff underneath.
Retro: The Chicago 1160 has a rather interesting history. In the early 1960s, as WJJD, it signed on at 4am local when KSL signed off AT 2:00AM Salt Lake City time. Then during winter months, WJJD had to sign off for 15 minutes when KSL came back on. After those 15 minutes were over, it was local sunrise, and WJJD got to sign back on. The "flip side" of that convoluted arrangement came during summer, when WJJD got to stay on as late as 10pm CDT.
Fast forward to the 1980s, when WJJD went fulltime with 5kw nights. The resultant directional signal was nowhere near adequate to cover the entire metro. That became painfully obvious when WSCR took over 1160 for several years before they moved to 670. Callers repeatedly called in with their nighttime reception complaints. The night signal problem was eventually solved by goint to the current 50kw from a second site.
