To be accurate, it's Mode A (reply code) you're talking about, not Mode C
(pressure altitude). And why would Flarm users filter out signals from
possible threat aircraft? Or did I misunderstand the statement about
turning warnings down/off?

Most of the US air space is covered by ATC radar and so my transponder is
pinging away in reply so I expect Flarm equipped aircraft would see me if
they came into my area. Flying out of Moriarty yesterday, I was one of only
two gliders to stay up and, in 2.1 hours did not get a single blip on my
PCAS. I verified that it was reading my transponder replies by changing my
code and testgin again. I don't think Flarm could have improved my
situation any.

I know I should have simply stayed out of this but... Fire away.

Doesn't having a transponder also alert the Flarm unit/user?

Mode S will tell every flarm in miles where you are. Mode C is next to
useless for flarm, and many flarm people will have turned mode c warnings
down/off.
