FLARM is very bad example especialy for DIY community. They have proprietary chips, firmware and are running non opensourced protocol. Also they are actively trying to prevent reverse engineering with cryptography and killing old/diy devices with protocol timebombs...

Yes, I am also not enthusiastic about the crypto part, but then if it prevents people from spoofing signals, it is probably a good decision.

The wikipedia suggests they use standard hardware components?
