Ed,
RIT will not help either, the pitch will still be at the peak of the
passband.
Now if you are only wanting to move it several tens of Hz, it will not
make much difference - in other words, a properly aligned 700Hz passband
centered at 580Hz will extend from 230Hz to 930Hz, but a 400Hz passband
will extend only from 380Hz to 780Hz, and for a 200Hz width, it is
likely to "fall off the edge".

Thanks everyone for your sage advice.....changing CW pitch sounds like
a pain to me!!
I think I'll use the RIT and see if it's worth all that trouble.

That is correct, AND if you have the KDSP2, you need to set those filter
centers to your new sidetone pitch in the DSP menu settings.
