Don't know your call Harry, but your question about RX EQ is a bit like
going into a mattress store and asking, "What pillow will be most
comfortable for me?":-) Only you hear like you do, only you can tell
what you like and then only by adjusting and trying it out. A couple of
suggestions however:
1. One adjustment at a time followed by way more than 60 seconds of
listening. The effects are subtle, and if you move too fast, you'll
just get frustrated ... and be tempted to post that the K3 RX EQ is
worthless, which has happened once. :-))
2. Test each setting under varied band conditions ... quiet SSB, CQ WPX
SSB [or whatever] before more adjusting.
My hearing is severely compromised and has been since one night 50 years
ago on the other side of the planet. I adjusted mine to look roughly
like the inverse of my audiogram. I need about 80 dB above 1200 Hz and
over 95 dB above 2 KHz, which is beyond the range of the RX EQ, but you
can get an effective 30 dB of adjustment range by lowering the low
frequencies, boosting the highs, and turning up the AF gain, if that's
your goal. It's not as good as my hearing aids, but then, my K3 is a
ham radio, not a hearing aid.
I've actually found that just using the SHIFT knob when on SSB, I can
quickly adjust the response for different voices if I'm having a hard
time copying a DX call or a really weak station.

I don't ragchew much and I'm not sure how to measure "punch," but I
started with K9YC's settings since he retired out of professional audio
and I know him, tweaked them a tiny bit for my voice with a local who
knows what I sound like, and often get unsolicited "great audio"
comments on SSB. My settings are:
1: -16
2: -12
3: -6
4: -2
5: 0
6: +4
7: +6
8: +10
YMMV, but in general the lower 2 registers, and even #3 to some extent
do not contribute much at all to communications efficiency. The upper 2
or so boost the sibilant components which do enhance the difference
between many words.
I use a Heil ProSet with the iC2 electret element I got from Elecraft.
I think you will find, if you spend enough time with it, that your
compression and mic gain/ALC settings will have at least as much effect
on the "quality" of your TX signal as the TX EQ, and maybe more.
The first four bars on the ALC meter are not ALC, they're showing audio
level. ALC action is indicated by the 5th and above [I think I have
that right, I'm sure I'll be corrected if necessary]. My shack is pretty
quiet when I'm on SSB, I run between 8 and 10 dB peak compression, and
set the mic gain so the 5th bar flickers as I speak.

Is there a list somewhere that gives some guidance on setting up the
K3 for good Audio.I've read a little about some of the various AGC
settings, but would like a bit more details.
