Zaon figured it out years ago. My PCAS does not alert on my transponder.
In fact, with a simple button hit, it displays my squawk code to verify that
it's giving me alerts based upon my transponder altitude rather than its own
internal pressure sensor.

Why can't the PFlarm simply eliminate the most powerful transponder
received? That would have to be your own unless another aircraft is parked
with his transponder antenna closer to your PF antennae than your own
transponder antenna and that ain't bloody likely.

It's not that nobody has noticed. I have posted about this issue before.

The reason FALRM implemented this change is that it is less bad than
having continuous alerting to ownship transponder.

Why would you want all transponders at co-altitude to be suppressed?

Because they have not figured out how to suppress the only co-altitude
transponder that needs to be suppressed - the one in the same aircraft as
the Power FLARM.
