Hi Lance,

Variable-passband CW filters are still under development. (We raised 
the bar pretty high with our fixed filters, and we're trying to make 
sure it stays high.)

We're looking at various bandwidth possibilities for these. One likely 
candidate is 300-800 Hz or so, in 8 discrete steps. We'll post details 
when we get there.
