I heard a distinctive signal behind KKOH, which usually dominates 780, and was able to mostly null the Reno station to hear news of a Chicago area fire, a report on vending machines and other news and weather that I matched with WBBM’s online stream.
The signal was weak, but peaked at times through the waves of fading until KKOH went back on top for good by about 0730 UTC. Even then, however, WBBM could be heard in the background. This one’s listed as 42 kW at night; distance from me is 1,699 miles.
