You really shouldn't need to increase the filter gains over what is 
necessary to equalize the filters. For example, I have my 2.8 and 1 kHz 
filters set to 0 db, and the 400 Hz one to +4 dB. I verified that this 
was correct by using a steady signal source (an Elecraft XG-1), turning 
the AGC off and using the dBv function to compare the gains.

If you need more headphone volume, first make sure that you have set the 
AF Gain in the CONFIG menu to HIGH. If that doesn't work, something's wrong.
