[Elecraft] APF ringing

[Barry N1EU]

Bob, I'm not sure how you are using the APF but I'll make a few general
comments from my experience with it.  The APF is intended for occasional use
only on weak signals that aren't much above the noise level.  And when used,
it requires careful fine tuning so that the signal is precisely centered in
the K3 rx passband.  

The "over powering and ringing" is by design, to make it effective in
popping those tuned-in weak signals out of the noise.  The APF was never
intended to be left engaged while tuning the band.

73, Barry N1EU
