I second that. There are a lot of turning to bring the notch from 2000 Hz to
near my pitch of 390 Hz. I would suggest the manual notch to be parked just
outside of the used AF band. I.e. when the width is 200Hz and pitch is

Actually, the situation in CW is not much different. The side emissions of
