Well, I got some updates made that allow me to download and upload to my radio (a Baofeng UV-5R) on Linux (Ubuntu 20.04, in case that is relevant).

All I had to do was to run 2to3 on the entire project, undo the double parenthesis on the print statements, and add a convert to byte to the download from radio method (when appending the model).

I also tweaked the File, Open filters to default to both .csv and .img.

Not having any other radios, I'm not sure what else I can do.
