You're still missing the point that in addition to the peak response,
there
is
also a deep null.
No I'm not! It can be adjusted with the 'phase' control to null a signal
*at IF* near to the wanted one. Adjusting the position of the null has
no affect on beat frequency with the wanted signal, or the beat
frequency of the unwanted signal (it gives the BFO a less strong IF
interfering signal to beat with but it does not affect the frequency of
the beat note, just the loudness). Tuning the BFO has no effect on the
null. The two controls do not interact, though they both have an affect
on readability.
