The path from the East Coast to JT is very similar to the
path to UA9UCO I experienced from Colorado in 1987. His signal peaked
at 210 degrees and was my first long path QSO from Colorado. Later I
also worked JJ1VKL/4S7 peaking on the same 210 degree bearing. This
path is actually more common than the over-the-pole path as the 2000
experience with XZ0A demonstrated to everyone on the East Coast...all
QSO's were to the SSW or W at our surise and NONE over the North Pole.
There are DX-Aid plots noting the similarity of geography from
W4ZV to JT compared to W0ZV to UA9UCO (Prokopyevsk in Zone 18) at:

P.S. We need new theories to explain the long path signals actually
follow...not the direct path which in fact is not the usual path.
