Re: ALPHA TYT MD-UV380 / RT-3S Installation information

Thanks, Roger! And for the backlight, yes, I did notice that the default had it at 100%, and I usually turn it down to 50% (until I need it very bright, like in an outdoor setting), and I know it does draw quite a bit of power (usually dot matrix LCD backlight seems to draw more than those for custo...

Re: New GD77's hard to find, discontinued?

As info for others, I ordered a MD-760 on AliExpress today but seller warned that new MD-760 are not OpenGD77 compatible....I canceled my order I see. Well, maybe the seller just wanted to protect themselves. If it is the real MD-760 (and e.g. they are not sneakily shipping you an MD-750, as the nu...

Is there a Quick Menu yet so I can check the Digital Monitor setting? (Or how to get to it?).
Quick menu can be accessed by SK1 + Green. This alternate is already in the GD77 I think
I must have missed it in the very fine manual, thanks.

Re: TYT MD-UV380 / RT-3S Installation information

Hi guys. Many thanks to the developers and testers, it is a really very interesting news. I am sorry for the dumb question, but not having that kind of radio I am not very informed and I would like to be as precise as possible with a OM friend of mine who owns it. Could this experimental firmware a...

Re: DMR full duplex operation i.e. tx and rx at the same time.

- Radioddity GD-88 (a handy radio). I own both of them. The Anytone implementation is currently relatively robust, it really works, after about 2 years of development (first implementations suffered from sync problems etc). The Radioddity radio is new, the firmware looks more like in the beta stage...

Re: DMR full duplex operation i.e. tx and rx at the same time.

What do you mean by Cross Band Repeat? Is the radio acting as the the repeater, transmitting and receiving at the same time ? Yes, the radio can do this in any mode combination, but one band must be set to VHF and the other to UHF. It operates symetrically, i.e. when somebody transmits on the VHF s...

Re: DMR full duplex operation i.e. tx and rx at the same time.

Hi! I tested the SFR mode with a pair od AT-D878UVs, one of the basic type and the second with extended memory and bluetooth (PRO version). Both these models have all the necessary Rx/Tx timeslot setting options to support SFR with 578 in their recent firmware. Regards, Pavel Thanks Pavel. I only h...

Re: TYT MD-UV380 / RT-3S Installation information

Just did an echo test on a DMR repeater and I heard myself fine, so it is working! Yay! My LCD is mounted slightly to the right, so the letter for the battery voltage "V" is somewhat behind the bezel LOL. I will see if I can open it up and fix it. I can still see it if I look at it from the left at ...

Re: TYT MD-UV380 / RT-3S Installation information

I followed your instructions and so far so good. One hiccup though, during the Flash Memory backup, it didn't complete and the CPS was hanged (I had to use Task Manager to end task), as I waited more than 15 mins, and th RT3s already reverted back to the normal screen (BTW, I didn't get the 1.666 MH...

Re: TYT MD-UV380 / RT-3S Installation information

I happened to be popping by and found this! Wow!

I am testing now, on my RT3s w/ GPSr. This will be my third OpenGD77 FW device, after GD-77 (own 2, one has a non working display) and RD-5R.

Thanks so much to Rogers and the development team for this! I feel I owe you all some beer and goodies!
