Alan, Walter, and All,

I have often visually observed the phenomena of intense Aurora waving and 
fluttering that would be in the range from rapid flutter to once every few 
minutes.  Aurora (both visible and invisible) also occur after geomagnetic 
storms, and can be many hundreds of kilometers long.

I observed a visible sinewave echo on VE7TIL's signal when he had QSB 
recently... His telltale sine wave signal was perfect for watching the 
effects of QSB.   There was the direct wave clear as a bell and an echo 
which arrived long enough later that you could tell it was another incidence 
of the same signal but significantly out of phase.  Consider borrowing 
Scott's signal format for a short period during your testing.  It is 
excellent for our experimental work.

It might also be good to check this site whenever the fading occurs, to see 
where the Auroral activity is relative to your area.  There may be a 
correlation.
