I have Mode S, but I still get those occasional targets in my lap and
never see any of them...Â* Is there a Mode S filter or does Flarm think
it's smart enough not to need it?

Why not use 0=aggressive?

I occasionally see PCAS targets at 0 altitude differential right on top
of me.Â* I assume that's my own ship, but it's very disconcerting to have
that pop up.Â* I'll have to check my config file...

Probably because if you have Mode S the Flarm can tell it's you, but if you have mode C all it can tell is there is some traffic nearby - perhaps you, or perhaps someone else.
