Re: IMPORTANT. New MD-UV380 or RT3S are not compatible

I received a walkie-talkie from Ali today. Doesn't run on OpenGD77. RT3S with GPS, s/n 2202R03S1100577 I hope there will be a firmware for these radios. Do you have a seal/sticker behind the battery over one of the screws on the radio ?, normally it's marked with year and month ( 1 to 12 ) Even if ...

I don't know what the "NEDECN codeplug" is, but I'm glad the radio is working for you
Guess it was "New England Digital Emergency Communications Network"

Re: IMPORTANT. New new MD-9600 and RT-90 may no longer be compatible

Do we have some report that MD-9600/RT90 have delivered radios with the clone chip? I see it more like a warning that it can be affected similar to MD-UV380/MD-UV390 /RT3S BTW, the subject "IMPORTANT. New new MD-600 and RT-90 may no longer be compatible" should be: "IMPORTANT. New new MD-9600 and R...

Re: IMPORTANT. New MD-UV380 or RT3S are not compatible

I checked and STM32F405VTG CPUs are still available in China e.g. https://www.aliexpress.com/item/1005004137675365.html So this is just a cost saving exercise by TYT. Perhaps someone needs to tell them, that the reason they are selling a lot of UV380 / RT3S is that people want to run OpenGD77 on th...

Re: Possibly not compatible with new Non-GPS MD-UV380 or RT3S

I have a non GPS rt3s arriving shortly, dunno the serial yet but I will notify here. Will be interesting to see what MCU this one has, just arrived from Amazon in Germany. It's a non GPS unit. But I have some German beer first (Weiherer Landbier) https://i.ibb.co/H7tqKj6/20230128-143821-2.jpg This ...

Re: RT3S firmware won't run

As Roger said, if your radio returns REV: 0x9 then it will not at the moment work with OpenGD77. None of the developers has one of these radios, so it is almost impossible to develop a fix. Just for completeness My RT3S returns REV: 0x100F which is different to Rogers but still works OK. My MD390 r...
