That's exactly right. Most mics should have TXEQ set for maximum cut of 
the three lower bands, with 6 dB cut of the fourth band, everything else 
set "flat" -- that is, no boost or cut. A few mics benefit from a few dB 
of boost in the higher two bands.

Once TXEQ is set, then set MicGain per the manual, then adjust CMP so 
that you see no more than 10 dB of compression on peaks of TX audio.

This will optimize audio for best communications quality, and for 
performance under weak signal conditions, boosting your "talk power" by 
nearly 13 dB. The recommended low-cut is typically good for 2-3 dB -- 
that's how much power is wasted by low frequency components of voice, 
which make no contribution to intelligibility.
