I built a fully featured Elecraft K2 a few years back.? It has a variable bandwidth crystal ladder filter.? I wonder if the uBitx filter can be adapted to vary it's bandwidth in a similar fashion, perhaps with an external pot rather than under processor control.
I,too have a k2 ...the diode used is a type 1sv149 500pf@1 volt to 20pf@ 7 volts ...been looking at that contemplating a test mod to see what happens for a while ...
