Bill,
The fact is that the receive filters can be configured for whatever you
want.
Of course, it is not productive to enable a 400Hz filter for SSB or AM,
but the check boxes will allow that if you desire.
Use some sense, and configure the filters that you have installed in
your K3/K3S in a reasonable manner. If you have the 2.1 or 1.8 filters
installed, you would want to select them for SSB RX, but selecting the
1.0kHz for SSB (or AM) would be "iffy" - similarly any filters that are
more narrow.
The filters that you select for any particular mode will determine which
filters will be 'stepped through' as you rotate the width (or
HiCut/LoCut) knob.
Yes, check the boxes for each mode only for the filters that you want to
use for that mode.
For transmit, the filter requirements are more stringent. Select the
2.7(2.8)kHz filter for CW, SSB and Data TX and the 6kHz filter for AM
and ESSB TX and the 13kHz filter for FM TX.

I am uncertain on how to configure the radio's filters using the K3 Utility.
I have the 6 KHz & 2.8 KHz filters. I am totally confused by Cady's book,
which shows (pg 27) almost all of the ENABLE boxes checked. This doesn't
make any sense to me since I doubt the hardware can be configured with all
four filters inline, and even if it could, why would anyone want to use a
350 Hz filter on AM.
