I've found that the APF is very sensitive to the multitude of AGC
settings available. I haven't actually broken the code yet, but there
are times an inaudible signal without APF rises to "copyable enough to
get a Q" with APF. Other times, not so much.
Just one more way to learn how to use my K3. :-)

Hi
OK got it now.
I was doing some programming of these functions looking mainly at the api and
things didn't seem to make sense.
Thanks!

Tom,
See page 35 of the K3 manual.
If APF is on, the SHIFT control set the audio frequency that you wish to
hear. NORM restores that audio frequency to your set sidetone pitch -
no other function is enabled.
The APF filter is quite narrow. While there is no downside to leaving
it enabled, your tuning filters will be very narrow - good for digging
signals 'out of the mud', but not good (IMHO) for tuning around to see
what other signals may be present on the band.
I would suggest APF off for general tuning, and turn it on when you have
to dig for a signal that otherwise might be buried in the noise or QRM.
