Just before noon today, I picked up a station on 990 with a Canadian quiz-type show. By the top of the hour, the signal was gone. I think it might be Winnipeg's CBW. If so, that would be 662 miles from my Lake Geneva, WI location. I've heard many stations on a winter mid-day from 200-300 miles away, but never this far. I was unable to hear any other stations from this area, either.
Is this actually unusual?
