Topband: Large TSTM areas as MF "wall"

[George & Marijke Guerin]

Charles, et. al.
    I think this is the same scatter type reflection used to make 6, 10 & 15
meter contacts with stations beyond the ground wave limits, and too close
for normal reflection off the upper atmosphere.  Normally there is short
skip reflection at the edge of ground wave propagation on the medium wave
bands that is stronger than storm front reflection.  This is due to higher
angle reflections back to earth at lower frequencies.
