OpenGD77

I am having an issue with my Retevis RT3S (tyt CPU) where if I am scanning and I land on an active static talkgroup from my hotspot, the audio stutters - indefinitely, even when the person transmitting changes. But If don't scan and just tune radio to static talkgroup, it works fine. Easiest to repr...

I am on the OpenGD77 facebook group, and people routinely get hung up UV380 vs UV390 flashing instructions since new users don't know UV380 refers to a "family" of radios including the RT-3S. Often people say the CPS doesn't list UV390.. or they are asking where the UV390 firmware is since they can ...

I had questions about my only DMR local repeater sounding pretty bad, when the analog repeaters around me sound phenomenal. So I got a MMDVM board from Aliexpress and setup WPSD on an old Raspberry Pi 3B+ to settle if it was the repeater or my radio. And the hotspot sounds sooo much better than my l...

I'm new to DMR.. Lets say I'm tuned to a repeater on TS2. Should the green RX light and the signal meter be active when nothing is happening on TS2 but there is an active talkgroup on TS1? I'll hear silence on the static talkgroup I have specified on TS2 the radio, yet the LED and signal meter will ...

I noticed GPS works indoors on my RT-3S and gets a lock quickly when I use the stock antenna, but it never gets a lock indoors when I use my 2m/70cm Signal Stick antenna from Signal Stuff. I didn't think the VHF/UHF antenna would impact GPS reception? Anyone have any ideas? :? The Signal Stick anten...

There are some threads on improving GPS - This one is about an easy to fix manufacturing issue: https://www.opengd77.com/viewtopic.php?f=19&t=3184 This thread has some very detailed instructions for modifications to improve reception (toward the end of the thread): https://www.opengd77.com/viewtopic...

Are there instructions for upgrading from an older OpenGD77 to a newer one? I managed to upgrade properly by just putting it in DFU mode and upgrading, but I am missing settings I changed on the radio. Is there some step I missed?

I thought someone had posted about how they got the CPS working with Linux using Wine, but I'm not sure whether they mean completely working in terms of Com ports etc. I recently came across this post from UB6LUM implying they got Wine working: https://www.opengd77.com/viewtopic.php?f=12&t=2091#p27...

Can anyone with a UV380/390 Plus, or a non-STM32 CPU UV380/390 please try this version and tell me the CPU information displayed on the Firmware info screen Here is my Retevis RT3S with October 2023 build date (according to security sticker in battery compartment). I never knew the OpenGD77 CPS had...

Just out of curiosity, is your RT-3S new ? The radio I ordered directly from Retevis.com has a build date of October 2023 and does seem to have better GPS.
