Andy,
I should point out that the High and Low latitude simulations are about the
worse one can expect in terms of signal distortion. The timing delays and
signal spread are what you might see during a magnetic / ionospheric storm. As
you know, the polar paths are usually the worse.

Tony K2MO posted this to the Multipsk reflector, I stole it (hope it
is OK, Tony) and posted it here for additional discussion. interested
measurements.
