[Elecraft] Which KSB2 bandwith do you like?

Paul,

My filter has the 2.5kHz capacitor values fitted. The bandwidth I get is less 
than that, probably 2.2kHz-2.3kHz. To my ear this is about right, and feel that 
anything less would start sounding too restricted.
It also seems to give a good response curve for rag chewing and DX/contest 
operation.

I would recommend grounding the crystals at their bases, however be careful not 
to use too much heat or damage the crystal case seals.
