Get this radio, use OpenGD77 right now.
My English is not good, I hope you can understand me.

I made this image based on GitHub images and added Chinese descriptions.

It doesn't have GPS, so I installed a GPS module, but it keeps restarting.
So I dismantled the GPS module, and now there is a noise floor when I am on the call, and sometimes it restarts or shuts down.
I am unable to fix it at the moment.

GPS module is 中科微电子 ATGM336H 6N-74 C92305
