Its not tropo, more like trans-equatorial backscatter. That is common on 10m
and 15m with no sunspots. The mechanism is the strong trans-equatorial
propagation that lets us work south America most days, the signals from up
north go south via TE then reflect back, we often work Canada that way because
we are just too far for ground wave. It is also possible, at least from here,
to work Europe by beaming south to south east when they are trying to work
Africa or south America.

Subject: [TowerTalk] 15m working like 6m trop?
Finished the 15m stack wiring yesterday in anticipation of perhaps getting it
into action on this weekend's RTTY DX contest. But of course there were
virtually no signals on the band. What I heard was the ARRL bulletin today and
yesterday.
Now here's the strange part. I'm in Kansas. Yet when I beamed to the SE (135
bearing), the signals from the ARRL were strong. If I pointed toward NE - the
usual ARRL bearing - the signal dropped almost to zero. In fact over the past 2
days the only signals I have heard are off of the SE bearing.
My question is if 15m can behave like 6m trop?
The only prop on 15m in the last couple of days (when I've been in the
shack) seems to be off to the SE. In fact some SA DX popped up from time to
time. But the ARRL signal was consistently (on the two days) hugely stronger
off the 135 bearing compared to the direct 40 degree bearing.
