On Upper  Sideband an audio note is heard when a signal is ABOVE the 
"effective BFO  frequency" and in order to bring that note to zero beat, 
one must tune  upward, lowering the pitch of the audio note until it is  
zero.


That sure is the way it works but it seems counterintuitive.  Upper  sideband 
implies the signal on the upper side of the tuned frequency.  If  you tune up 
from zero beat, the signal should start at zero and go up in pitch,  not the 
other way around.
 
Bottom line is "upper" and "lower" do not refer to which side of zero beat  
you find yourself.  What does upper and lower refer to?  Or - you are  upper or 
lower in reference to what?
