The RX EQ doesn't seem to do much for me on CW because I am already
limiting the response by the DSP bandwidth. Normally I use 300-450 Hz
for tuning around, and then narrow the bandwidth as needed for weak
signals or QRM. My passband is centered at 520, so I don't hear the very
low and high pitched signals anyway. If I am calling CQ and want a wider
passband, then I wouldn't want to limit it further by using the EQ.
I have tried various settings like Joe's below and I don't notice much
if any effect.

The K3/K3S stores separate RX EQ settings for CW and SSB. The
appropriate setting is recalled based on the operating mode. I have:
CW = -16, -16, 0, 0, 0, -6, -16, -16 and
SSB = -16, -16, -6, 0, 0, +3, +5, -16
Those are certainly valid settings for one way of operating. I choose to
keep K3 RXEQ set flat for both modes. My reasoning for CW is I'm mainly
a contester, so I want to hear off-frequency signals calling me at the
reduced levels that result from the IF bandwidth I've set. On SSB,
because I'm already limiting the LF response by setting of the IF
bandwidth, and high frequency peaking tends to increase the audibility
of splatter.
But the important point is that there's no single setting that is
"right" for everyone, or for every style of operating.
I do things differently with the KX3, because the audio output stage is
current-starved, so it doesn't have much headroom. So for the KX3, I
roll off the three lowest bands on both modes (max cut), leaving the
others set flat (no boost, no cut). I would suggest the same settings
for the new KX2.
