The new APF continues to please this CW operator.
Like others, I find it works better in some situations than others.
But I would not have been able to copy and work RI1FJ
(Franz Josef Land) on 160m the morning of November 8
without this new tool.
A few suggestions for using it:
1. Make sure the CW signal is centered in the passband at your
selected pitch, before engaging APF. For very weak signals,
I always rely on my ear to match the pitch, rather than using the K3
SPOT or CWT features.
2. After turning APF on, use the APF SHIFT (now 5 Hz resolution)
and/or FINE tuning (1 Hz resolution) to peak the signal.
3. I've mentioned this before, but I use a Macro to turn on APF,FINE,
and RIT with one button push (and another Macro to turn off all these
functions).

"Yes, it helps on some signals but not on others.
In fact, due to the "ringing" or hollow sound, the weak signal is better
copy with normal operations. If have I/II so I can switch back and forth
quickly.
I use the 400 narrow filter. NR,NB, etc off.
Anybody have any suggestions that can bring this station up to what others
are reporting that they experience?"
