just to add my two pennies, I am what I would call a casual CW
contester. I got the 250Hz 8 pole now I often think that was not the
best decidion and should have used the 400Hz filter in rare cases the
250hz pay off in tight situation. Most often the 400hz would have
probably done better as I don't see that many big signals here and the
chances that there is one withing 400HZ is not that often. when I am
wider than 250 I do find that there is sometimes a biggies too close for
the 1.8 filter and agc starts to get in the way. so the 400 would have
been best for me.

Thanks all for the replies. I was leaning toward the 8 pole 400hz filter
since it is described as having steeper skirts for cutting off adjacent
interference. I am a person who runs the K3 on cw with the DSP at 400hz as
it stands today with the dual PB option (narrow) on at all times. I find
its a cleaner signal to listen to. You just have to be careful to tune
around the bands slowly or you will miss signals. :)
So it seems most favor the 400hz filter for what I was understanding it to
be so I guess my gut was right! I also ordered the internal antenna tuner.
I just sold my Ameritron AL811 amplifier and have my Palstar AT2K tuner on
the market as well. My plan is to run with the internal antenna tuner and
100w only until I can save enough pennies and get the KAT500 and KPA500 and
have the entire elecraft line! Plus it will all conserve some space on my
shack desk! :)
73!
