Dave,

Sounds like you may be a candidate for the dual-passband CW feature of 
the K3. It gives you a 150-Hz "focus" filter, but allows you to hear 
signals either side of this at about -20 dB (the "context"). The 
context width is adjustable with the WIDTH control. See the manual for 
further details.

We've corrected the knob material problem, and will send you 
replacement knobs on request (no charge). Most of the defective ones 
have already been replaced. Sorry you had to deal with it during the 
contest.

Thanks for your other comments on how the K3 performed.
