Since I am blessed with a Corsair II, I use the manual notch filter for
some DX contacts. When I worked T32C on 40 meters CW, I had the Corsair
II with the 250 Hz filter in, and some lid was still QRMing them very
close to their frequency. Careful adjustment of the manual notch filter
and the audio filter took that jerk out.
I have never operated an SDR radio. I am very impressed with the
performance of the receivers in the Argonaut VI rigs. I'm hoping that
Ten Tec will get something nice into production before my Corsair II
wears out.

Quick poll:
How often do those on the list actually need or use your notch filters?
Most of my QSOs are CW contest QSOs.
Many times the bands are so crowded that a ginsu knife would come in handy and
yet I rarely need the notch filter.
I'm just curious...
