I’ve been watching the digital modes on VHF/UHF shift around past couple years, WIRES, D-Star etc. But the radios are too expensive. I don’t want to ever pay close to $400 to $1,000 for a handheld radio.
t’s coming from Baofeng of course. The new DA-77 is a full up DMR radio. And the price – $129. So I’ll jump in.
Now on to what DMR – it’s a digital encoding based on 12.5KHz channels. It stands for Digital Mobile Radio. A bit of misnomer but then a handheld is in fact a mobile radio. If you want to go you can read the protocol specifications here.
It’s interesting that the ETSI who controls the DMR standards insists on calling it a “…licensed land mobile…” service. Amateur Radio in the United States isn’t just restricted to terrestrial use – there are a number of satellites whizzing around in the sky right this moment. Plus there is an amateur radio presence on the International Space Station. So Amateur Radio in the United States isn’t a land mobile thing.
But for the capabilities and price – once the DA-77 is available I’m buying one. The reason I think DMR will win in the long term is that the others I mentioned are WIRES (Yaesu) and D-Star (Icom). But they don’t play because they are proprietary protocols. But DMR is open in the sense that ANY manufacturer can use the standard. So there will in fact be a whole lot more DMR radios than WIRES or D-Star out there. if price is the driving factor that is. And believe me, it is!
