My PF Core picks up all ModeC/ADSB targets perfectly well, while stationary in my city street in front of my house. Most of the traffic is on approach into a major airport at 3000ft, 3.5NM laterally displaced.
If I open up my ranges in the configuration file, I can see also departing traffic much further away and much higher.

There have been reports here on RAS from people evaluating the PF and MRX side-by-side, who have concluded that the latest PF firmwares outperform the MRX.

Do you understand what your $PFLAC,S,OWNMODEC,1 is for ? (I have mine set to 0)

3U.

I also flew with Zaon for years, and then with both for at least a year, in which the Zaon out performed the powerflarm significantly at the beginning until my powerflarm went through couple of firmware upgrades and eventually I also replaced a faulty antenna, after that the powerflram consistently outperformed the Zaon, especially in altitude difference which the Zaon often did poor job. I eventually sold the Zaon.

As for what you noticed on the ground, this is in purpose. When powerfalm detects you are on the ground, it shuts off Mode C alerts completely. This was confirmed to me by Flarm support when I noticed this couple of years ago..
