No.
Its a completely different radio to the DM1801
The hardware of DM-1702 is quite different from DM-1801 - but it's very similar to RT-3s: STM32F405VGT6, HRC6000, AT1846S.
Unless someone cracks the firmware encryption, it would never be possible to put any firmware on this radio.UA0LMC wrote: ↑Sat Sep 24, 2022 10:59 pmThe hardware of DM-1702 is quite different from DM-1801 - but it's very similar to RT-3s: STM32F405VGT6, HRC6000, AT1846S.
So I hope it will be possible to port opengd77 to this radio some time in the future.
DM-1702 and DM-X are basically the same radio in different cases, even the main PCB in my DM-X is marked as DM-1702-V1.4
Also GPS receiver module in DM-X is the same as in RT-3s (ATGM-336H) - but GPS antenna is waaay better.
It even looks like when making RT-3s they've thoroughly read the GPS antenna docs - and done exactly the opposite
Don't know if it's the thing - but please check https://github.com/OK2MOP/MD1702-tools
Looks interesting, but the tools in the folder only upload the firmware and codeplug for the radio, it does not seem to contain any information about the firmware.UA0LMC wrote: ↑Mon Oct 10, 2022 9:12 amDon't know if it's the thing - but please check https://github.com/OK2MOP/MD1702-tools
Looks like it can read/write firmware - or at least that's what author said in the description.
Implies that there must be unencrypted firmware for this radio somewhere.To update firmware, an unencrypted firmware image is required.
