Baofeng DA-77: Dual-band DMR radio

Baofeng DA-77Jason KC5HWB, Joop PA2JM, Carel PA3EHA and I had some pre-production pictures of this radio for quite a while, but some preliminary specs are now public.

The good
The most interesting fact is that the Baofeng DA-77 is a dual-band radio, something which didn’t exist so far. The second most interesting fact is the expected price point: $129,00.

The bad
Things bothering me a bit: only 160 memory positions and a meager 50 zones. Enough for professional use, but compared to the Connect Systems CS-700 (250 zones of 16 channels each) it’s far from impressive.

The ugly
The shell is identical to that of the UV-82, something I don’t like either. I do understand the decision though; re-using existing shells is much more cost effective than designing a new one. Another advantage is that accessories such as batteries are interchangeable.

Both Jason KC5HWB (Grapevine Ham Radio) and me are on Baofeng’s list for getting a review sample. To be honest I hope Jason gets one first, as he’s much more knowledgeable in this area than I am. Keep an eye on his blog.
