K3 Dual Passband CW Filtering

Neal
I guess I could wait until I get my K3, but inquiring minds want to know.
   
  I understand that the narrow (focus) filter is a fixed bandwidth and that the wider (context) filter bandwidth can be varied.
   
  What is the width of the focus filter?  Also, I assume that the context filter bandwidth must be narrower than the roofing filter that is activated, or do the roofing filters simply track the context filter bandwidth as it is narrowed like normal filter adjustments?

Currently it is 150 Hz.

Yes.  Context is currently limited to 600 Hz at its narrowest.
