[Elecraft] K3: Is Width of Notch-Filter adjustable in some reasonable amount?

[Bill Frantz]

It also works wonders to filter out loud PSK31 signals that are 
overloading your audio A to D converter. Too bad auto notch 
doesn't work in this situation. (I'd go after the strongest 
signal in the DSP filter pass band.)
