[Elecraft] Settings for CW filter 400hz

[KD7YZ Bob]

Howdy K3' people:

I need help setting the parameters if my 8-pole 400hz filter.

Recently a friend explained the advantage of using a narrow filter on the
mode JT9-1. He has a Flex5000. I have a K3.

So I tried today to get a waterfall display with the 400hz filter and
despite turning up soundcard and all, I could not.

Yesterday I was able to fiddle with Width/shift and CUT/Lo/Hi and
actually get s,ethg to get me down to 1khz. But I hadn't selected XFIL
anything at that moment.

I have 8-pole 2.8 , 4kHz , and FM filter .


I need some guidelines on how to select the cw filter while listening to
the JT9-1, very-narrow, signal then I can buy the 8-pole 250hz CW filter
for both the Sub-Rx and Main.

thanks
