OpenGD77

It's strange that the screen is cropped at the bottom

None of the RT84 users reported that problem

What's also strange is the gap at the top of the screen.

Have they loaded the DM1701 instead of the RT84 Version?

I think we may need to add the version name to the firmware info screen

Not sure on the age, I will try on a different radio and see if it is still present. definitely when the backlight is on, but wasn't there in the original firmware. i will get it back to stock and see if its still present The official firmware does not support dimming of the display.

So I pulled the pin and ordered a DM-1701B from China, which firmware file would be the one to use for that unit, OpenDM1701 or OpenRT84, I can see that the DM-1701B is referred to as “aka Retevis RT-84” in another thread..

The Chinese Hams say the firmware works ok with the 1701B

The board looks to be populated with everything that the GPS version has with the exception of the GPS receiver, a couple of components on the receiver RF input which might be amplifier or filter (or both) and the GP...

Hi, I read in one of the topics that it is possible to upgrade the GPS in the RT3s GPS version but does anyone know if it is possible to upgrade a non-GPS RT3s to a GPS using the same method? Regards Dave G4UFS Yes. It's relatively easy to fit a GPS into the RT-3S. There will be an unpopulated comp...
