Hi Dave,

When you reduce WIDTH in SSB mode, the center frequency is maintained 
(at 1500 Hz), because the K3 doesn't know if you're reducing WIDTH in 
order to cut the highs or the lows -- it just does both.

Instead, you can:

- tap one of the knobs to switch to LO CUT/HI CUT instead, and do a HI 
CUT

Or

- after reducing WIDTH, use SHIFT to move the passband where you'd like 
it for best clarity.

You can save two settings you like (in each mode) using the NORM1/2 
feature, or presets I/II. These are covered in the owner's manual.
