Thats nice. If anyone gives anyone any trouble about that, it's a

unlawful, at least in the US.
Only for international communications.
97.309(b)
Where authorized by §§97.305(c) and 97.307(f) of this part, a
station may transmit a RTTY or data emission using an unspecified
digital code, except to a station in a country with which the United
States does not have an agreement permitting the code to be used.
RTTY and data emissions using unspecified digital codes must not be
transmitted for the purpose of obscuring the meaning of any
communication.
I know of no international agreements concerning D-STAR voice.
If someone thinks they think they can _mandate_ a secret and
proprietary encoding scheme only available as a potted black box—
isomorphic to encryption— on amateur radio... well, I'd be amused to
see them try, and if they succeed I look forward selling one off
custom opaque codecs to anyone who wants to run a private repeater
without prying ears and lids butting in.
This is exactly what /has/ been done to us, with the cooperation of FCC
and pretty much everyone else at the time.
What you can say is "never again".
Thanks
