[Elecraft] APF suggestion

That's the problem dumping too many functions into one box, I think. I have
an Elecraft AF1 Audio Filter between the K3 and my phones. It's an active
filter offering the same bandpass characteristic as the APF using analog
devices except that it also offers two selections of "Q". 

I can't decide whether one is better than the other: the APF or the AF1. But
it is nice having separate controls for the filter function.

What do you propose for those of us that use the Notch all the time? Should
it just be removed?
