Encryption to obscure your communication is technically against the rules, but things like D-STAR need a proprietary decoder (the spec isn't open) to be decoded, so some people consider that encryption even though it's pretty popular and not being shut down: http://www.amateurradio.com/encryption-is-already-legal-its-the-intention-thats-not/ http://www.amateurradio.com/encryption-is-already-legal-its-...
- tjohns 11y agoD-STAR is actually an open standard. The only part that's closed is the voice codec (AMBE). But if you just want to transmit or decode data packets, you can definitely build your own hardware. There's even a couple SDR modules for it: http://www.flexradio.com/amateur-products/flex-6000-signature-series/waveforms/ http://www.flexradio.com/amateur-products/flex-6000-signatur... http://www.rtl-sdr.com/listening-d-star-digital-voice-dsd-1-7/ http://www.rtl-sdr.com/listening-d-star-digital-voice-dsd-1-...
