OpenGD77

I have no doubt that OpenGD77 is indisputably better than the original. I already have this software in GD77, RD5R and of course DM1701. The purpose of returning to the original software in DM1701 is related to an attempt to repair a model that was damaged when the original software was upgraded. T...

Is it possible to restore such a radio from Ali... with the OpenGD77 software loaded by them to the factory software? I ordered two such radios from them, but the original software was supposed to be left in one of them, of course they didn't understand and installed OpenGD in both of them. Yep, no...

I am looking for a diagram for DM-1701 or its equivalent, because I have the impression that there is a hardware failure. After the first upgrade, still with the original firmware, the radio stopped transmitting and receiving on the set frequencies. I made various attempts with no success. Now, aft...

It's amazing. I want to alert friends that the antenna is active. This dear RT3S uses a passive gps antenna. But no problem, to make the work easier, I advise you to remove the pcb components and then connect the small coax directly to the (positive) of the antenna and of course not forgetting the ...

Hello everybody! Finally! New GPS antenna installed. Excellent results! 28db antenna, installed on top of the radio. When activating the gps, in one minute the gps starts to receive the satellites. Amazing, I wasn't expecting it. Indoors, he obtained 9 satellites. (And with the exact location of my...

Hi all, I'm having some troubles with the volume knob, and I'd like to ask you if anyone faced anything similar. Once I turn the radio on rotating the knob, it shuts down as soon as I go a little further (as everybody would do to increase the volume); at this point, if I decrease the volume turning...

Oky !


NOTE:
DFU Mode is reached with: SK1 + PTT (As far as I've been able to check)


Thanks Daniel.
