I once took a course in Change Management, that is, selling improvement processes to people in an organization. The leader gave us all kinds of suggestions, but also pointed out that some people will never change, but they will die at some point. Change is inevitable.

Unless it's from a vending machine. ;)

Most of those are card-swipe/NFC these days. Which is the point, I suppose.

Open protocol works on me and I am a D-STAR fan over the other DV methods in the hobby. *I* don't like that all three (D-STAR, YSF,
DMR) *all* use DVSI's IP to encode the voice. It's the one thing about D-STAR I don't like. OK, there are some other things I don't like about it but those are out of scope. :-)

But it's not 2010, it's 2024, so onward. We've largely ... well ...
maybe not *largely* ... solved the D-STAR<->YSF<->DMR interop issue with reflectors that will transcode between all three (it *is* between all three, right?).

Now we need a new scheme that doesn't depend on anyone's IP but our own and M17 appears to be it.

A couple questions:

For those of us that do keep up (mostly): Source code is considered a published work and can be copyrighted. Who owns the copyright on
CODEC2 Has Dave Whose-VK-call-escapes me patented any of the methods
within it (ideas can be patented)? If so, what license are they released under? Same question, really, for the copyright.

All the same questions apply to the M17 protocol.

For D-STAR, it looks like JARL owns the copyright on the protocol, DVSI owns all the IP related to AMBE, and Icom owns the trademark on "D-STAR". Trying to figure out the equivalents for M17 in case someone asks me.


On selling to the majority of amateurs that *don't* keep up what is the elevator pitch? DV exists and people are either using it or shunning it. **Without talking about intellectual property** what is the big deal about M17?
