I got mine from Jim, K9YC, a retired audio professional designer and
consultant in large venues. They are:
1 -14
2 -10
3 -6
4 -2
5 0
6 +4
7 +6
8 +10
I don't frequent phone much but when I do [like in an NAQP SSB or SS], I
usually get one or two "great audio" comments. While most of that is
undoubtedly due to superior DNA, I think the K3 TX EQ has something to
do with it. [:-) Close-talking some mics tends to boost the lows too,
sometimes significantly.
Jim points out that there is no value to power in the low frequencies,
they carry almost no information. Watching the P3 waterfall with a
narrow span demonstrates dramatically how many SSB signals have all the
power in the lows, crammed up against the suppressed carrier, and next
to nothing out where it would be beneficial.

I just finished writing a python program to make it easier to control
the K3 internal EQs. The impetus is to easily adjust in response to
on-air reports, or to adjust when using MON to listen to myself in
headphones.
One of the things I've done is to include a file of presets drawing
from recommendations of knowledgeable hams. An example is shown at:

Are there are other recommendations from anyone? I'm especially
looking for recommendations coming from those with substantial audio
background. The idea is for us audio neophytes to steal, er, learn
from the learned!
I'm restoring a Heathkit line of DX-60B xmtr, HR-10G vfo, and HR10
rcvr. The DX-60B is cw or am, so I've become interested in AM
settings of late. :-)
Tnx es 73!
