Within the last half-hour, it has been reported to me from at least 6 other 
hams all who live within 10 miles of me...and by one who lives 100 miles 
north of me.

ALL of them report very serious interference which they were never able to 
"characterize" nor find the source since it sounds so very much like 
extremely loud "band noise" or "white noise".

I suspect that very, very few hams would even recognize it for what it actually 
is, and thus it would never be reported.
