I'm assuming this would be attributed to troposheric ducting. Worked some 2m ssb guys in northern il and into wisconsin around 8pm. This isn't all that uncommon...200-400mi 2m ssb. Then things got way better. I chat with some local guys about 25 miles south on 446.000 simplex usually 10-11 pm. We had a breaking station I let him go. Come to find out he was 25 miles west of Madison wisconsin! 279 air miles from me. We had no trouble working each other. Both of us running comet verticals around 30-40 ft. We decreased power to 5w...still no problem! We then tried out 220 simplex..again no problem. So we jumped to 2m ssb...5w 5/9. Then to round it out 146.520 simplex..no problems 5w. I had too much fun and just wanted to share! 73 all..
