Something has changed the identification string for your radio to something that CHIRP doesn't recognize.

I have modified the RT22 driver module in a way that should all CHIRP to temporarily download from/upload to your radio. Please test the attached custom driver module to see if it works for your radio.

Here is how you use the custom driver module.

save the custom driver module to a convenient location (DO NOT RIGHT-CLICK THE LINK. Left-click the link and then on the page that loads, left-click the download link near the top left corner.)¶

click Help¶

enable Enable Developer Functions¶

click File¶

click Load Module¶

locate and load custom driver module that was saved in step 1¶

The CHIRP background will now be red to indicate it is running with a externally loaded driver module. You can now test the custom driver module.

Test by downloading from your radio. Once you obtain a successful download, save it, unedited, to a CHIRP Radio Images (*.img) file and attach it to this issue. Once I have this "image" I can determine the best path forward from here.

Note: The test driver module does not permanently change your CHIRP installation in any way. Every time you load CHIRP you must load this driver module to have access to its fixes or added features.
