The factory setting for the Contour control in these radios is ok, but I prefer to turn the adjustment from being a frequency muter to being a frequency booster. It really makes it difficult to copy audio pop out from the noise. I find 2500 Hz to be the sweet spot to boost. This applies to FTdx1200 and FTdx3000 series HF radios, and probably a lot of others! Watch the video below.
