This is excellent advice. Most hams put far too much gain in the front
end and rely on AGC to reduce it. This squeezes the dynamic range
quite badly, and makes it very difficult for your brain to separate
signal from noise. I NEVER use the preamp below 20M, and the
attenuator is always engaged below 30M.
BTW -- in the olden days, hams learned to turn down the RF gain to
match it to band conditions. This is an important operating skill that
many need to learn.
And, like Guy, I like 2.7kHz bandwidth for casual SSB, 1.8 kHz for
contesting.
