Hi Bert,
Congrats on the K3s/P3 and getting into CW.  It's a great way to
communicate and have fun!

You are going to receive many different answers, and all of them will
probably be correct.  As it's a personal preference as to how one likes
their rig set up for CW reception.  Some 40+ years ago, I loved my sidetone
set at 650Hz, but now 420Hz is the ideal sweet sound to my ears.  Yours
will differ, experiment.

In my K3s, I have in both the main and sub receiver, filtering of 2.8, 2.1,
1.0, 400, & 250.  Lots of folks will say I wasted money on the filters, as
some of them are very close in response, but again, my preference.  When I
am on the radio in the CWT's, I have my filtering set for 400Hz, and then
use my "wet" filter (ears & brain) to filter beyond that. I will drop down
to 250Hz if someone gets a little close to me.  When I am in S & P mode, I
might get down to 100Hz filtering to help zero in on a station, especially
if it's weak, again my preference.

I keep saying "my preference" because today, that's the way I like it, next
year, good Lord willing, it might be something different.

The best advice I can offer is to experiment with the radio and see what
works best for you.  That can change on a day-to-day basis depending on
conditions.  So, you have to be dynamic on your settings and never believe
it's set in stone.

A good read is Fred Cady's - KE7X, now a SK, book on the K3/K3s radio and
how to use it.  It has many good pointers and lots of valuable
information.  I believe PDF formats are still available on LuLu publishing.

I hope that helps a little.
