Perhaps Flarm
and Zaon should get together and discuss building a single, small
device that detects Flarm mode, A/C/S transponder modes, and ADS-B

Zaon is not involved, AFAIK, but you're looking for what's called a
"PowerFlarm". You can upgrade your existing Flarm unit with a
"bluebox" and a display, or buy the PowerFlarm.
I suspect it only works with ModeS xpdrs, not mode a/c.
