Another question: Has the magnetic polar drift affected propagation over the
decades?
I don't have any data except my own unreliable memory and old logs, but my
feeling is that back in the 1960-1990 time frame long haul DX propagation was
better than now, at least for my operations from Indiana, Colorado and
Massachusetts.
It's interesting that the magnetic pole moved less in that time frame and then
rapidly accelerated up to the present.
It seems to me that DXing was better back then, but it's difficult to separate
that from the declining sunspot cycles and the changes in ham demographics.

Hi Dave,
Thanks for posting that interesting article.
What effect, if any, does this have on beam headings through the Northern
regions – like UA0, UA3, JA?
Does it change them at all? If so, how and by what amount?
Tnx & 73
Bob, KQ2M

Good thing HF antennas generally have relatively wide beam width if you use
a compass to orient without correcting for deviation.
This also has a subtle effect on propagation paths through the polar areas,
depending upon your location.
