Does your S meter reading of the heterodyne drop when you notch it? No it does
not. Therefore, signal level is attenuated by the degree of notch depth, due to
the action of the AGC, which is still dominated by the heterodyne. Useless...
Once you have used a notch filter that IS inside the AGC loop, you will
appreciate why it is important.
