As the FM DXing season winds down, one of the most surprising things about it this year was the complete absence of any sporadic E propagation. I spent much more time on FM this year than in past years, and I heard no sporadic E propagation on the FM band at all. There probably was some when I wasn't listening, but nothing while I was.
No complaints, however. I've been very successful with receiving new stations via tropo. And the season's not quite over yet so maybe there's more to come.
