The exception, I assume, is with a strong local signal in the passband that
causes clipping or requires reduction in rf gain. I use the notch filter
for that OR get on the same tx phase with him.

Yes, that makes sense. I should have realized that the narrow filtering had
to be done somewhere.

One thing I haven't seen discussed on this reflector is improving the S/N by
narrowing the receiver bandwidth. It is no surprise that decreasing the
bandwidth received increases the S/N, by 10 to 15 dB, sometimes more. When I
see a station I want calling
