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

[Bill Frantz]

I guess I'm just not getting it. I am in DATA A mode with the 
13KHz FM filter automatically selected. Following Wayne's 
directions, I put the bandwidth controls into Lo/Hi mode and 
hold NORM to normalize the passband. I then turn the Hi knob to 
max (4.00 shows) and the Lo know to minimum (0.00 shows). When I 
look at the bandwidth displayed in the waterfall on fldigi, the 
computer is getting audio from about 150Hz to 3000Hz. What am I 
doing wrong?

I am using a Tascam UX-122 mkii as a "sound card".
