Not quite what I recommend. My "starting point for typical ham mics
like the Yamaha CM500 headset is:
Bands 1, 2, and 3: Maximum cut (-18)
Band 4: -6
Bands 5, 6: 0
Band 7: +6
Band 8 +6
Set Mic Gain and CMP for indicated Gain Reduction of 10 dB on peaks.
Then, get signal reports from trained listeners who have their IF
bandwidth set for 2.7-2.8 kHz. These are settings for maximum audio
"punch" to get through QRM and noise. They get rid of un-needed bass
which makes no contribution to speech intelligibility and boosts highs a
bit because they DO contribute a lot. Ignore reports that tell you that
you lack bass -- you don't want it, because it wastes TX power.
These settings increase the effective voice power by about 13 dB
(multiplying power by 20).
