Hi Scott,

I think there is not such a function so far. There is just a range where 
you can limit the auto notch apply, like 0...500 Hz.

Today i improved the readability of a CW signal. The side tone was at 
800 Hz. The filter has a BW of 200 Hz and 50 Hz slope. This is the best 
setting for a solid signal. Then i choosed the auto notch function but 
limited the operation range from 0...780 Hz and moved the filter so that 
the CW signal is still passing. These steps make the readability better 
than choosing a 100 Hz wide CW filter without the notch function. So the 
best (for optimising CW) would be to have two (or in your case: several) 
limiting ranges, i my case: 0...780 Hz plus 820 Hz...2000 Hz. I asked 
Wolf if this is possible to implement but the easter WX was to good 
here, HI. And there are several other querys on his table too, i am sure :-)

Wolf? :-)

Best 73, Stefan/DK7FC
