Re: Retevis RT3S / UV380 Teardown

This radio was a lot more expensive than the GD77 and it seems the quality of RF performance is lower. This radio was sold around $130 whereas i got my GD77 for $70. That`s like two times cheaper than the RT3S. The only advantage was the big screen and more memory.

Re: OpenGD77 on the Baofeng DM-1801

Now that it is working, i should get a DM-1801 from China, thank you. (In Turkey, greedy people sell these DMR radios 3 times more than the normal price, A DMR radio is sold as much as half of the minimum wage here).

Re: Port this firmware to Md380 and others...

Is there any chance for porting OpenGD77 to RT3S in the future ? I mean hardware wise, which radio would be the next possible candidate in terms of compatibility ? Thank you.

Re: Experimental version with option to disable CC filtering

I just tried the latest version and have no garbled noise anymore. I just tested with my radio, and holy cow. It's still pretty horrendous using my hotspot. Very experimental. I don`t use hotspot for testing, the latest experimental firmware works just as before for me. I had my HT monitor private ...
