TYT MD-380 / RT-3 - Not supported [FM only sources]

Post by VK3KYY » Tue Mar 14, 2023 12:21 am

Current Status - Not supported

This radio is not currently be supported because it uses an older DMR IC ( HR-C5000 ) which does not function the same as the HR-6000 in the supported radios.

Known problems with the HR-C5000 are :

* Existing DMR source code, written for the HR-C6000 does not work with the HR-C5000. The IC hardware interface, registers and commands, for DMR operation is different; This functionality would need to be written from scratch.
* Does not support FM CTCSS Tx or Rx; This functionality would need to be written from scratch using the CPU
* Does not support FM DTMF; This functionality would need to be written from scratch using the CPU
* Does not suport the "OpenMusic" channel used in the firmware for beeps; This functionality would need to be written from scratch using the CPU


The amount of work / time require to support this radio is large, and none of the active developers have the time or interest work on converting the firmware to work with this old radio.


Sources for the FM only UHF MD-380 / RT-3 can now be downloaded from here

downloads/releases/MD380/R20230319_UHF_FM_ONLY

These sources are not totally in sync with the latest UV380 sources but the radio does transmit and receive on UHF FM

Thanks to Colin G4EML for all his work getting the MD-380 even to work on FM, as this radio has completely different RF hardware to the UV380

Can this firmware be flashed on MD380? Can you provide a tutorial on flashing the computer? Thank you!

Old story - There is since a version of OpenGD77 that works great with TYT MD-380 and Retevis RT3. Take a look here: viewforum.php?f=19

No, openGD77 is not supported in the MD380 / RT3 single band radios. The hardware is different.
