Yes, I know what the manual says. However the IMD on my K3 goes up when
I set the mic gain to flicker bar 7 on voice peaks so I run it with
almost no ALC. I also set the TX EQ using the "K9YC Method," and
regularly get unsolicited "great audio" comments so I'm a fairly happy ham.
I'm not on SSB often, but when I do get on such as NAQP SSB, I'm always
a bit surprised at how many signals have all the sideband energy crammed
right up against the suppressed carrier. Not too many fill up their
BW. For those of us with compromised hearing, it makes copy difficult
... one of the several reasons I don't get on phone very often. All
that low frequency energy contributes almost nothing to intelligibility.

Hi Fred,
The ALC level you recommended is the recommended level for digital
modes such as FT8 where *no ALC* is the standard practice.
Elecraft's recommended for the K3 or K3S ALC level when operating in
voice modes is *5-7 bars.*
The exact quote from page 30 of the latest K3S manual
https://ftp.elecraft.com/K3S/Manuals%20Downloads/K3S%20Owner's%20man%20A1.pdf
Optionally select TX TEST mode (pg. 13) or set power to zero. This
will not affect your CMP/ALC bar graph readings.
Set CMP to 0
Hold METER to select CMP/ALC metering
While speaking into the microphone in a normal voice, adjust MIC for a
peak ALC meter indication of about *5-7 bars* (see below).
Adjust CMP for the desired speech compression level while speaking.The
CMP scale shows approximate compression level.
