[Elecraft] NB and NR algorhythm

[ANTHONY JAPHA]

I'd like to add a similar suggestion, this one about the APF in the K3.  I accept that it works as intended, but it is not useful.  I've used APFs for many years and they can be very useful.  The need to severely narrow the bandwith to avoid ringing and the poor peak in the audio when the APF is peaked limit the current filter.

What I'd like to see is an APF that does not depend on a narrow bandwidth and that has a pronounced (tunable) peak at the desired frequency.  It does not need to be extremely sharp, but it could be if that is dictated by design considerations.  And, to keep it simple, there also does not need to be a choice of bandwidth through the menu,   

I'd like to hear others' ideas.
