[Elecraft] K2 SSB Bandwidth

[TR, WB6TMY, K2 S/N 838]

Does anyone know...

I don't have my manuals in front of me now, but it seems to me there 
is a filter on the SSB mod board in the K2 that sets the bandwidth.

The filter is built with crystals and there is no way to tune 
it.  You theoretically could change the fixed capacitors to widen out 
the bandwidth, but you'd have to know what you were doing and have 
access to a network analyzer to monitor the passband shape.

Has anyone thought of this or done it?  I would like to broaden the 
SSB to 3KHz wide.
