[Elecraft] Best CW Pitch and filter ripple

[Ken Kopp]

I like 450 hz...

I've also found that trying to use anything much lower results in the
case someone else has given ... the opposite side of zero beat starts
to appear ... decidedly undesirable ... for me anyway.

Slightly related ... I note see four distinct "gain peaks" in the 
waterfall
display of my PSK-31 program(s) when using wider filter settings.
I assume is is a product of the crystal filter's "ripple'.
