I have, in my K3S, the standard 2.7 kHz filter for transmit and often
use the 1.8 kHz filter for receive to deal with QRM. It is necessary to
adjust the SHIFT in order to improve copy when the 1.8 kHz filter is
active. Yes, this is perfectly normal, the 1.8 kHz filter is not going
to allow the audio to be Hi-Fi quality. That's the nature of
"communications quality" audio.

With the recent experience in SSB contests, I'm thinking of upgrading
my SSB filter(s). Currently for SSB I have only the 2.8 filter. What
are thoughts about other SSB filters? I know when I narrow the
bandwidth to 1.8 the intelligibility goes down.
