[Elecraft] K3: just how wide is it?

Hi Doug,

> OK...just how wide is the bandwidth when "limited by the K3's BP filters?

For what it's worth...

A quick and very dirty attempt to "simulate" one of the filters using  
Elsie 2.12 (free version) gave me in the 10m band filter a -3dB width  
of roughly 2.7MHz, after some tuning -> 40pF trimmers to 32pF. I  
assumed a Q of 1000 for the capacitors and 200 for the inductors.

Maybe using Elsie or the AADE filter designer might help give you a  
rough idea, if you can't do simulations with Spice.
