It also looks likely that we will be able to develop a version which works on the TYT MD-2017 / Retevis RT-91
Currently the DM-1701 version still has some problems with the user interface keypad mapping, but we hope to improve this as soon as the DM-1701 which I ordered on 4th March arrives.
The latest firmware for the DM-1701 can be downloaded from here
The CPS is already being modified to support loading firmware onto these radios.
See the version of the CPS with the newest date in downloads/CPS/Latest/
