I hope that everyone realizes that setting a high value for averaging 
cancels non-correlated noise in spectrum displays, including the 
waterfall, greatly increasing the visibility of correlated signals and 
noise. Correlated can be understood as non-random, and includes nearly 
all ham transmission modes and most electronically generated noise like 
computer clocks, trash from electronic power handling and switch-mode 
power supplies.
