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.
