The software is similar but not the 100% same.
There are different global settings between the two but I believe the system and scanlist programming is the same.
Therefore, you can copy a VFolder (CDAT folder on the PC disk) from one radio type (TRX-1 vs. TRX-2) and then open it in the respective version of the software but you then need to properly set the global settings (General Settings and Advanced Settings tabs).
I believe the other option is to delete the global settings file in the copied CDAT folder before opening the respective destination radio software.
