New APF Filter

[Roy Morris-6]

Wayne,
The new APF filter works well.  When you sweep the APF frequency across the desired signal, it is as if the NR is on.  You hear the desired signal and nothing else.  Thanks for making this feature possible.  Roy Morris  W4WFB

I can hardly wait.  This is the one feature on my ancient TS-930s that I
have really missed. Please, please, please.....

This begs the question or note, that if scanning mode is set up and
monitored by the P3 with the APF engaged, one could see where those very
weak and elusive signals are lurking in the shadows?

I don't think so.  APF is working at the DSP IF stage which is well beyond the (1st) IF OUT which the P3 and other panadapters such as LP-PAN use.  As I said previously, I could detect no visible signal from 5R8RJ on CW Skimmer's waterfall but it became audible when APF was engaged.
