[Elecraft] K3/K3S: How to adjust SSB receive bandwidth up to 4.0 kHz

[Bill Frantz]

I think my problem is with fldigi. I tried using cocoaModem, and 
it shows audio up to 4.2 KHz when I follow Joe's technique of 
setting the knobs to SHIFT/WIDTH, the SHIFT to 2.20 and the 
WIDTH to 4.00. Sorry for the bandwidth.
