I wonder if you Chicago Area DXers ever heard WITL 1010 when WCFL was off for some reason, as it went Straight West with a 3 tower 1 2 1 binomial cardioid pattern. Also, WVIC/WDFN 730 when WGN was down, but that pattern is not favorable. WSGW 790 radiates enough to hear on "LSD" with WBBM on the air. My hippie cousins called Lake Shore Drive "LSD". WSGW is a major obstacle to WBBM increasing back to 50 kW Day, as the 0.5 mV/m contours nearly overlap under old rules, and unless that changes back, it's 0.5 mV/m to 0.25 mV/m mutually.
