We hear this over and over, but it is very misleading. It's true that if you have a good
readable signal, a difference of a db or two is not noticeable. But when the signal is
right at the noise level or QSBing in and out of it, even one db makes a difference. As
N2WN said, it can be the difference between "?" and "N2?" -- or even between the guy CQing
again and "?".
