Hytera Radios

[Steveradio]

Well been checking into digital systems for work and its a idea they been throwing around, not one to demo radios unless we are serious about switching over. Been to a few resorts already indoor and out door who seem to like the systems, not much to complain about.

Was reading the web site provided by Hytera (License Free PMR446) radios that operate in the 446.00 to 446.100mhz range, the extent of service we need would not be just enough for simplex operations but just curious if anyone else played around with these or not and range of the license free frequencies:

License-free radios (PMR446) from Hytera

Thanks, trying to learn more and sometimes reading/youtube doesn't help but others experience does
if we would build out digital the range would need to cover about 80 miles road way hills and valleys. Curious on stand alone systems.. Current using LTR trunking encryption which keeps going south.

PMR is license free in many countries in Europe, but not in the US. In the US, those frequencies are in the ham band and a ham license (and the associated non-commercial use rules apply) would be required. A close analogy for that band in the US would be FRS radios.

In addition to what n5IMS said, it is also very low power, half a watt I think, just like FRS.
Even if PMR446 was offered in the US, it's not going to cover the 80 miles with hills and valleys that you require, then again, I don't think anything will without the help of networked infrastructure costing in the hundreds of millions of dollars potentially.

Huh?!?!?!?! 80 miles of road... even with out knowing the terrain, he will not be needing 'hundreds of millions of dollars to cover it. Seriously.

We do know the terrain. The OP said hill$ and valley$.

That wasn't a price quote. I just said it could cost hundreds of millions of dollars POTENTIALLY.
Potentially means it could. It also means it might not. There is the potential for it.

Read the fine print. :wink:

Wouldn't cost hundreds of millions using high power base stations in VHF low band but something tells me the OP was hoping to use little walkie talkies in a car.

Lol uh ok... hundreds of millions... maybe if he was building out a system to cover an area the size of Alberta, with a P25 phase 2 system... potentially

And by doing that, you are misleading the guy... hes using an LTR system... at least keep the upper price in the same Galaxy... he wants to cover 80 miles of road, not 250,000,000km sq.

So what's it cost to build a site every 100 square miles or so?

That's what I was getting at.

That Hytera webpage is for Europe. Look for dealers on that page, & see what countries other than the US is covered. 446 mhz in the States is ham territory. Wrong radios for the US.

hmm does anyone outside of us use that?
