I agree with Tom -- it's noise from far away, propagated just like
any other RF signal. When 6M is open, for example, I hear birdies
that I don't hear when it isn't. And during a major blackout not
long ago, it was noted that the bands got real quiet at skip
distance from the blackout, even though they were open.
