Puxing jumped the bandwagon too and introduces the Puxing PX-780/PX-820 DMR Tier II radio. Prices unknown at this time; you have to mail them through Alibaba.com for more information.
The radio is available in both VHF and UHF versions. GPS appears to be a standard feature.

Not one of your tasty pasty clipart mods eh Hans?
Saying all that I feel this is the year of the mass produced DMR handheld, and if it comes at us at the right price the end could soon be nigh for Death Star!

Let’s see what the quality is like, Steve.
What I’ve seen and touched so far in the low budget DMR section must still bow to the Connect Systems C700.
The proof of the pudding is in the eating.

It works fine, I tested with Motorola radios. Similar programming, soft
is very good. Quality product.
I just received a shipment of these radios and will be posting them to GrapevineAmateurRadio.com this weekend.
Do we just not care about FCC certification for commercial rigs any more?
IDK, since this isn’t a commercial rig.
For Amateur rigs, it is preferable yes, but not 100% necessary.
Not a commercial rig? With frequency ranges of 136-174MHz /400-470MHz, that is certainly not exclusively a ham radio … (Grin)
Not exclusive, no. But not commercial only either.
There are probably commercial DMR repeaters, but I haven’t researched them. I’m planning to use this one for Ham Frequencies.
the antenna is GPS & radio 2 in 1 design, does it build in GPS function ? And does it can talk with other band DMR repeater just like the CS700 ?
For the first question you have to contact the manufacturer. Sometimes specs on paper seem to promise more than you really get. The radio will function on any DRM network.
