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.
