This makes sense to me. Can the NEC-based modeling
programs do that ? They seem to consider different
ground conditions... but what if ground is 350 feet away ?
Good question.

More of the mysteries of propagation ... I think
many hams know very little about the vagaries
and effects of propagation -- and I am one who
needs to learn more about this aspect of radio.
Hams often talk about take-off pattern, yet blithely
ignore what might be happening to the signal after
it leaves the the back yard.

I thought there was a school of thought that
based the signal strength component of signal
reports on S-meter readings - in which case it would
matter to them whether or not S-meters were
1) accurate, and 2) consistent between rigs.
If so, then I think this would be a worthy topic
for beating to death. ;-)
