Don, it is customary to give a freq which is the freq the software is
showing on the waterfall. Frankly, it is next to useless for many of the
spots that show a dial freq. All too many people do that and spot something
like 14.070 or 14071 or 14069. when I see spots like that, I click on the
spot, and there is NOTHING there, in most cases. I have used 4 different
PSK software packages, and every one of them spots the same way - giving the
waterfall freq - not the rigs dial freq. If you give a freq of 10133 - and
I click on that spot, my "sweet spot" on the waterfall lies on THAT exact
freq. It doesnt care what your rig readout is, nor what you offset is. You
gave a freq, and it is looking for something on the waterfall at 10333.
Every sound card has its own "sweet spot" where it outputs is maximum audio
output, and lies within the high portion of the input curve as well. That
sound cards offset is automatically added to the rigs dial freq, to get to
the spotted freq. Or if you want to look at it that way - The program looks
at the spotted freq, and subtracts (or adds) the sweet spots freq to the
dial and the CAT places the rigs freq where it is needed, in order to get
the signal in the correct spot on the waterfall.
In my case, with an offset of 1 kc for this particular sound card, it places
the above waterfall spot at 1 KC above (I use USB) the rigs readout, which
in this instance would be 10.132.
