I use an unusual setup for CW myself. While still centered on 600 Hz,  
my filter settings are:
1000
400
160
OP1

I chose 1000 because that's the largest size of the variable filter  
where it still has one peak with smooth sides. Larger than that, the  
filter starts to get a second "hump" on one side.

1000 is kinda narrow for quickly scanning the band. But it is a good  
width for most conditions. 400 is good for congested contest  
conditions. I rarely use 160.

OP1 works well on an empty band, when you are searching for activity,  
like on 10m these days. But, it is hard to zero-beat stations with  
this filter.
