No one's mentioned the "Spotlight" phenomenon, which occasionally
happens
on 160. The signal comes shining down from the "upper layers" and
illuminates a very small area. Stations lucky enough to be in the
covered
spot get to work the DX. Everyone else, well...
Can't remember where I read about this, but it would mean that your
being
250 miles from the other station might place you well out of the
covered
area. You'd never hear the DX, regardless of how many antennas you
had.
