P3 and APF were an excellent in the contest for S&P. P3 set up for BW of 2 KHz would show weak DX, and APF would pick it up. The position of P3 next to K3 beats a panadapter window on a computer. I worked tons of DX without ever looking at the cluster. Just look at weak signals on P3, tune and work.  Signals not showing on P3 were generally too weak to copy.    

APF was different story for RUN. Turning on APF was too slow. Having an option to switch XFIL and APF for CW only would be great. I guess software APF toggle change via PF key may be good enough.  

P3 was very helpful for finding a "clear" frequency and also adjusting it, with a  twist. That is, the "free" frequency could be used by a DX that was too weak to hear (without APF) but visible on P3.

Some gremlins got into N1MM here. Every so often, written callsigns would disappear,  SPLIT would show up, and work frequency would change from 1820 to 18200. Reloading CONFIG would cure it. Not sure whether it was KUSB, RF or Vista.
