[Elecraft] SHIFT pitch

[GM0ELP]

Hi,
I find that shift has to be reduced progressively as width is reduced on SSB
eg.

2.7KHz width  *1.5KHz shift
2.1KHz *1.25KHz shift

As I decrease the WIDTH past my 2.1KHz roofing filter with DSP, I constantly
adjust SHIFT downwards to achieve normal sounding audio eg.

1.8KHz 1.1KHz shift

I asked Lyle about it and he said that for SSB, LO and HIGH CUT should be
used instead of WIDTH for SSB. WIDTH is meant for narrow bandwidth modes
i.e. CW.

Personally I find LO and HIGH cut arkward to use, especially when you have
optional roofing filters installed. This is because the primary function of
NORM is overloaded to automatically select the 2.7KHz roofing filter???. The
secondary function of NORM (I/II) means you can have a some defaults, but
try remembering what's behind them in the middle of a contest (if you get
enough time to select them).

It would be nice if the primary function of NORM just normalised the current
filter width around the current shift value.
