The baud rate of D-Star is too high for the current HF regulations. In
addition, it is 6K00F7W ... F7W is only authorized above 51 MHz.
Finally, I'm not sure anyone would appreciate 6 kHz wide digital voice
signals in the already crowded HF bands.

I agree, if it's not open, it's not ham radio.
We use FM on 10, 6, and 2 - modes included in the KX3/K3s, maybe the
future should include d-star.

You have listed 3 digital voice modes that do not talk to each other.
Furthermore, I recall that these are proprietary coding schemes.
That is not "Ham Radio" in my mind. Ham Radio is "everyone can talk to
everyone else", and those digital voice systems where you can only talk
to those hams who have purchased the same brand of equipment as you have
selected is more like commercial circuits where you want to shut out
those who do not 'speak the same language that you do'.
I don't think proprietary protocols belong on the ham bands - just my
not so humble opinion. Yes, I am also opposed to proprietary data modes.
