People who get a radio sent from China need to realize should the radio need to be returned to China, the return shipping costs more than the radio. China subsidizes the shipping costs from China to North America, but it doesn’t work that way going back.

$65.24 for a gd-77 on amazon for a short time. Sold by radioditty and fulfilled by amazon. Might be worth the trouble, but probably not.

I find that I'm having issues receiving DMR traffic. Tx is fine.

CPS ver 2.0.5/fw 3.0.06.

I understand new versions are available, but I can't make any sense of how to install this software or upgrade the radio. Can anyone shed some light on the how to?

Semper Fi

Everything I've been reading states that it only does 400 - 470 Mhz TX
There are other radios that will do 400 - 480 Mhz TX

Looks interesting , Will this radio do 477MHZ analogue TX ?

Since it is not a commercial radio, anything above 450 and above are not legal in the US anyway so it is a mute point. I have read from more than one source that the GD-77 (and other low end DMR radios) are actually made by TYT. Looking at some of the CPS for various radios tends to confirm this.

I think you mean moot point.
Yeah I agree about the radio info

It will program up to 512 MHz or so with some hex editing. I've never used anything above 485 with a GD-77, but it definitely works up there.

The GD-77 is an go it alone by Radioddity. Its their upgrade of the old GD-55 flop. They just upgraded the format a little more so it actually does DMR Tier I and II and actual dual time slots properly. Its one of the few they went in on and then took over completely. Their other joint venture is with Baofeng on the RD-5R, which they did not go alone on. From the reviews on youtube by a few amateur radio guys, its actually a pretty good radio, and audio wise, is outstanding. If I was not dead set on saving up for an Motorola XPR, I'd pull the trigger on one.

Not quite. It's actually manufactured by TYT (it's the MD-760) and rebranded by Radioddity, along with their own custom-built firmware. Radioddity does not actually make radios, and for that matter, they don't actually code the firmware either. That is outsourced as well.

It is definitely a very good radio for what it is. The receive is as hot as any of my 7550e's, which arguably have the hottest receive out of any radio on the market. The front end is lacking, of course, and the internal memory is lacking compared to some of the other DMR amateur radios on the market, but it's a great little radio.
