Yeah - Jumper uses text bases .INI files to save the models.
If you plug your radio in with USB, hit enter in the USB menu (main screen) it will show up as a hard drive.
Go into the models folder and copy (DO NOT EDIT) it to your computer (may have to figure out which model# it is...)
if you want to use the PC to edit the files, use notepad++ (free) - DO NOT use regular notepad as it will goof up the files.
