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.
