Don,
thanks; my ears are worse than normal, not better, so not a problem,
just ab observation. And I finally got it worked out how to use the
Norm settings, so all is well now.
It seems I am still learning my way around my K3, and will be for some
time; it keeps amazing me at how versatile an
Thanks Sam, that solves that part of my question.

Dave,
A 50 Hz difference will not make a significant difference in the
received audio unless you have greater than average ears.
You can "preserve the setting using the Norm I and Norm2 settings, but
for the most part, I just use the Lo-Cut and Hi-Cut knobs to dial in
what is best for the curre
David,
OK, I have perhaps ignored the subtle points - in some cases, you will
have 50 Hz rounding and in other cases, you will have 100 Hz rounding -
that makes little difference. 50 Hz to a SSB low frequency response
does not make much difference.

Don,
thanks for the reply.
1. when I try using the Lo-Cut, it seems to be confined to 100 Hz
increments, so, 150, 250, 350, but no 200, 300, or 100 available; is
there a way to set that differently?
2. I can accomplish the same thing either way if I understand what is
going on, but
Dave,
Yes, the default is 1500 Hz. with a 2.8 kHz filter, that puts the low
end at 200 Hz and the high end at 2900 Hz.
AND that is why you should be using the Hi-Cut, Lo-Cut on SSB instead of
Shift and Width.
For good intelligibility, you need to have some content in the 300 Hz
range, so set
I note that as expected, the center frequency of the bandpass of any
given filter on SSB seems to be 1.5 KHz, whether its the 6 KHz filter,
the 2.7 KHz filter or the 2.1 KHz filter.
This seems to work out to be passing from 150 Hz to 2.85 KHz, right?
So the 2.1 KHz filter (without using the shif
