It's a vocoder so it's gonna sound mr roboto.

again I didnt like the Harris digital voice either. Its me..
Okay...stop making sense ...my head will blow up

Firstnet is still an 8 billion dollar pipe dream. VoLTE is still

Tetra isn't an option because there aren't enough 25KHz channels
to make a large system work in most cases. And if you want to see
expensive try out a tetra terminal. They make P25 look reasonable.
By the way, Motorola invented Tetra too.
Blaming Motorola for inventing something, and then not wanting to
give it away is simply rediculous. Would you do that?
Lastly, you are not seriously comparing a $100 Chinese piece of
crap to a piece of gear you would bet your life on are you?
Really? About the cheapest P25 portable you can get is $1250 while
the same model without P25 is about $855. So the license to do P25
is about $400. Pretty pricey no doubt. Maybe to much, but also
reliable.
But, not everyone wants the reliability, interoperability, or the
price tag that goes with it.
I honestly think DMR TIER 3 has some compelling arguements at a
better price point. But like most other protocols it is late to
the party.

P25 or Project 25 was a Motorola proprietary technology that
was developed in the 80’s. They championed it to APCO to
become the digital standard for public safety radio systems.
APCO would not adopt it until Motorola agree to license it to
other manufacturers. That delayed the process a very long time
and Motorola went kicking and screaming in to the agreements
at first. It was not cheap for a manufacturer to go that way
but APCO did not want a single vendor solution. In the rest of
the world the Tetra standard was adopted but again this are
older technologies. Now the push is for LTE and Voice over
LTE. When the FCC mandated narrowbanding for analog VHF and
UHF radio systems they gave a 15 year window to migrate. Even
with that much lead time big cities like NYC, Boston, DC and
others did not make the deadline because it was typically a
complete system replacement. These big cities got waivers with
a plan to migrate, those plans were special licenses for the
Firstnet spectrum and the plan to develop a public safety
grade/reliable voice over IP type network to become their
primary dispatch radio system in conjunction with their data
deployments. That VoLTE development is ongoing. They need a
lot more reliability than what Nextel and CDMA push to talk
cellular solutions currently deliver.
Given that VoLTE development and the push for FirstNet
systems, many folks argue that it’s a waste of money to go P25
at this point. There are even some Tetra deployments now in
the US. Seems to me a standard that follows LTE and will also
work in the narrowband spectrum of public safety radio systems
is more productive. I started my wireless career in public
safety radio designing and selling Motorola systems. I think
they build a great product but P25 radios are way too
expensive for smaller agencies to afford them. With the
proliferation of sub $100 FCC approved Chinese radios out
there, it’s real hard to justify these digital systems when
one is on a budget. P25 radios are in the $1500 per radio
price range. Small fire, EMS and law enforcement agencies have
a hard time paying those prices. There are benefits to digital
systems but in all honesty many users don’t take advantage of
them. The cost of the central site controllers for the system
really pushes the price tag up. To add insult to injury almost
all federal grant programs now state that if there are radios
involved, they HAVE to be P25 compliant. The DOD has mandated
all radios be P25 compliant. If Utah is getting grant money
that is probably why they are going P25.

Illinois has state-wide P25 (owned and operated by Motorola
Solutions). Interoperability between agencies and all of the
other P25 stuff is nice, but every little town can't afford it
and that's why we still have little dispatch centers that
represent small communities and make use of regular old analog
VHF. Plus, a lot of users on the state system say the coverage
sucks, and that would be Motorola not building enough sites.
