>>1836711If you're talking about running some SDR set up to imitate/spoof aircraft comms, yeah that's probably possible now but not with a smartphone.
You'd need a decent SDR and you'd need to reverse engineer the signal to be able to imitate it, all doable. Then you need enough transmit power. That's also about the time they're going to start looking for you and they take that shit real serious.
But I agree, civilian aviation is archaic by todays standards.
