Jim,
I am not certain what you are calling "ring and sound hollow", but on my
K3 I can hear what I believe is audio limiting on strong signals - it
happens on both SSB and CW and has nothing to do with the filters (I
have only the 2.7kHz). I believe the cure in my case is the AF mod, but
I have not yet installed it. You might want to consider that mod to see
if it makes any difference.

Greetings,
I seem to have a problem with either how I set up my K3 or with the
filters. When first built the radio, I had only the stock 2.7 filter
in it. I noticed that the receive audio began to ring and sound hollow
when the bandwidth was reduced to about 1K. I now have the 1K filter
in position 3 and the 400Hz filter in position 4. (I may add a narrow
phone filter in the future in position 2.) Filter widths are
configured at 1K and 400 respectively. All filters are enabled for
both cw and digital. I note that the filter in use does coincide with
selected bandwidth but again, as I narrow down to 1K or tighter, the
received sound is still hollow and ringy. BTW, only the 400 Hz filter
has gain added in the configure menu to offset its loss. Have I done
something wrong?
Tnx,
Jim W5QM
