Believe it or not, in some SSB contests I've dropped the hicut down to
as low as 1100/1200 Hz and still been able to copy some voices. It's
really dependent on the voice characteristics of the operator on the
other end, but it works often enough to be usable in heavy QRM.

Bill,
For SSB use LoCut and HiCut, not shift and width. Shift and Width
will drive you crazy because each time you reduce the width, you will
have to adjust Shift to maintain a good center frequency. HiCut.LoCut
adjusts it automatically.
Set the low end between 300 and 400 Hz initially, then set the high
end initially for 2800 to 2900. If there is QRM on the high frequency
side, reduce the HiCut, and if there is QRM on the low frequency side,
increase LoCut.
You will find that you cannot cut the low frequency end very far
before you lose intelligibility, but you can cut the high end
significantly. While you will lose the voice characteristics, it will
remain intelligible down to 1600 or 1800 Hz.
