is hardly a waste of time and money. D-Star was developed FOR
amateur radio. P25 was developed for the Public Sector market.

D-Star is wonderful, and while the Codec is proprietary as I
believe is the case with the P25 Codec, the rest of D-Star is an
open standard.

Frankly, I think Yaesu trying to implement the P25 digital mode
instead of going with the ever growing and already established
D-Star digital is a mistake. Just like their Wires linking
protocol. They went this way while others went with Echolink.
Hardly anyone in the U.S. has implemented Wires.

1) I agree that WIRES is basically a flop. However, Yaesu is
*NOT* pushing P25. They are promoting DMR ("Digital Mobile Radio"
a.k.a. "MotoTRBO"), probably by re-purposing existing commercial
land mobile models for ham use. <br>
<br>
2) Once again, Motorola's marketdroids have taken an open
standard and given it a catchy vowel-challenged name (in the same
vein as "Razr", "Rokr", "Astro25" - their name for P25, etc) in an
effort to suggest it is unique to Motorola. <br>
<br>
"MotoTRBO" is Moto's trade name for "DMR" (Digital Mobile Radio), a
standard defined and documented by ETSI (European Telecommunications
Standards Institute). DMR is quickly becoming a mainstream digital
radio format for NON-public-safety land mobile users; i.e. business
dispatch, utilities, etc. (In North America, the public safety
establishment is digging itself ever deeper into the insanely
complex digital radio tarbaby known as P25.)<br>
<br>
3) The same proprietary DVSI (Digital Voice Systems Inc) codec is
used in <b>ALL</b> of these digital radio systems to convert the
voice input down to a 4.8 or 2.4 kilobits/second data stream. The
DVSI royalty on every radio (which can run as high as $100 per
radio) is becoming similar to the "Microsoft tax" on every computer,
Android phone, etc. <br>
