Hi Thomas,
Unfortunately I don't have the knowledge to debate the physics theory
behind TB propagation, but my experience in ZL, which is now approaching
one solar cycle, is starting to indicate the opposite. Certainly the
long path between ZL and G has already shown a couple of good openings
this season, and I made more Eu contacts in Mar/Apr 2008 than ever
before in a similar period.
