The original APF never worked for me when used with weak 160m sigs in the
noise - the ringing made it more difficult for me to copy than without it.
I have not had a chance to try it under 4.51 (until I finish my FCP :-)
Less ringing would be good for me.

The high Q goes hand in hand with ringing,  I actually try to adjust for the most ringing, hihi,  it is hard to
explain but I find a more "piercing" sweet spot this way.
