Turn your contour control into a voice enhancer with this simple adjustment of your Yaesu HF radio.
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. Watch the video below.

This applies to FTdx1200 and FTdx3000 series HF radios, and probably a lot of others!
Give this a try and let me know in the comments what you think!
Yes, the contour is useful. But I find that both cases exist. Certain voices in the presence of noise seem to benefit from suppressing the voice at about 1200 Hz, creating a “hole” in the response. This might be because the information content in the middle frequencies is low, so getting rid of it gets rid of more noise than signal. I have a FT-1000MP and a FTDX3000D.
