The secret is there's already tons of encrypted communications on the bands because of cheap chinese DMR radios that unlicensed teenagers use for airsoft and the like. It has yet to ruin ham radio and nobody has even noticed enough to attempt enforcement.


DMR isn’t encrypted. You can listen to them with any SDR. The voice codec is patented but well known. DMR itself is a standard.


DMR can be encrypted, and I know from experience that there are people (not me, but people) running encrypted DMR on ham bands.


Occasional, random uses of encryption would not attract much interest.

But as soon as some company sets up an encrypted node in a location that will attract users, there will be much interest in what it's purpose is.

The whole point of the regulation is to make defying the regulations on a commercial scale a risky operation.


Those radios are very low power, so they don't really get in anyone's way.


There are power limitations on spread spectrum emissions in some of the bands, you could have the same thing here.
