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?
