My filters are 6, 2.8, 2.1.1.0 and 0.4. 1.0 and
0.4 average to 0.7 so I think I have it covered ;-)

When the 2.1 and 250 filters switch in, the
signal level in the earphones doesn't seem to
change, but the noise level does indicating an
improvement in S/N. Perhaps they are sharpening
the cutoff of the DSP filter removing some of
the off-frequency noise?

In the K3 Utility -> Configuration tab ->
Configure Crystal Filters,
you will see that each filter has a Gain
setting. You can change the
gain on a per-filter basis to maintain
approximately the same overall
gain. Generally the smaller bandwidth filters
require a few more dB
gain than wider ones.
An example:
13 KHz: 0 dB
6 KHz: 0 dB
2.8 KHz: 1 dB
1.8 KHz: 2 dB
0.25 KHz: 4 dB
These settings work well in my K3.

I am narrowing the bandwidth in both CW and
SSB, when the K3 switches to a narrower
filter, there is a noticeable step down in the
noise level that doesn't occur when just
narrowing the DSP bandwidth one notch.
