Yet another new radio

This makes three that I own.

The inventory as follows:

  1. A Yaesu VX-7Rb does 70cm, 1.25m and 2m translation from 400-480MHz, 222-225MHz and finally on the 2m side it’s 144-148MHz.
  2. A Baofeng B580T does 70cm and 2m
  3. And all new a TYT MD-380 70cm DMR radio

I’ll be very honest here I like the MD-380 – it’s a very solid radio. The entirety of it cost me $100 but for an HT that does digital that’s pretty impressive. It comes with battery, metal belt clip, two antennas one stubby the other a whip, and charger stand and plug adapter as well as programming cable and software. It also comes with a fairly comprehensive manual even if it is in Chinglish. As an example of the latter it’s on the very first page where it states:

To Customers

Thank you very much for using TYT our two-way radios. This product has a newly developed function menu and humanism operation design, making it easy to use.

The humanism operation design bit really gives it away. And Chinglish if you’re wondering is original Chinese translates into English where certain things just stick out, like the above.

Once it’s charged up I’ll install their software, see how crappy it is and then go with Chirp instead.

Amateur Radio: Stealing the Thunder – Cheap DMR radio coming

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!
