Hi Bill,
One thing we learned many years ago in pro audio is that in general,
it's a bad idea to use "boost" EQ, especially to boost a lot of bands,
and to boost them a lot. The reason is "headroom" -- when you're
boosting a lot, you're more likely to hit digital clip on audio peaks.
I suggest that you subtract 10 dB from each band. The only band where
you'll change the shape of the curve is the top one. And if you're doing
the cut in that band to minimize noise internal to the K3, simply
increase the RF gain a bit (or turn off the ATTEN and reduce the RF gain).

The following are the settings I am using on 40, 75, 160 for armchair
copy (meaning very reduced hiss and no ANF warbling). My RX audio goes
through amplified Behringer studio speakers with bass/treble adjustments.
The speaker adjustments: bass at 3 o'clock and the treble at 11 o'clock
K3 settings (Config Menu):
AGC DLY - NORM
AGC HLD - 0
AGC PLS - NORM
AGC SLP - 4 to 6 (low setting reduces artifacts from the Automatic
Notch Filter)
AGC THR - 12
AGC F - 120
AGC S - 20
Shift - 1.25
Width - 2.7
RF Gain - 90 (sometimes less)
ATT - ON
RX EQ 1 -2
2 0
3 +9
4 +12
5 +11
6 +14
7 +7
8 -16
