It reduces the low frequency energy getting to the speech compressor on
the KSB2 board.

Changing those two caps changes the audio or band width of the signal?
Thanks

Ed,
Change 2 capacitors on the KSB2 board. C34 to 0.47 uF and C32 to
something in the 3300 pF to 5000 pF range.
I usually run SSBC at 3-1 and SSBA at 1 with the Elecraft MH2 microphone
and it sounds good with those changes made.

K2 serial number 3600+ using the Heil hand mic that Elecraft sells, also
did the KI6WX wide-band mod years ago. When on LSB using the elecraft
recommended settings of SSBA of 2-1 and SSBC of 2-1, I get lousy reports
that there's too much base in my audio and hams find it hard to hear what
I'm saying, but when I turn off compression I then get really good audio
reports!
So, for the K2 wizards out there, as long as I leave the compressor off,
my hams friends are happy.......so, I'm wondering why turning on
compression increases the base response and if there's a way to improve
audio when using SSBC 2-1? I've used Spectrogram to slightly adjust audio
filter bandpass but doesn't do much.
As always, thanks for everyone's help!
