I wonder about propagation with the earth's polar shift which is also 
overdue.  North pole becomes south.  Birds fly north for the winter. 
Compass point north downward.  If it is a geo magnet shift, then we are all 
in trouble because the continents will ski around atop the crust of the 
earth and the planet will rattle like a baby's rattle.  It will be a 
worldwide earthquake.  The bands will be filled with so much magnetic noise, 
even if we are alive, no one will be calling CQ and getting an answer; 
that's for sure, haha.
