I stand corrected, it's NOT P25, rather MotoTrbo.  I am familiar with both.

      is hardly a waste of time and money. D-Star was developed FOR

      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.  


    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.         


    "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.)


    3)    The same proprietary DVSI (Digital Voice Systems Inc) codec is
    used in ALL 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.
