Next I tried reading the radio from Chirp, (Download from Radio).   That fails no matter what I try it will not download the file from the radio.

I believe the MOD is Expanded RX or TX I do not recall as I've never needed to perform the mod was aware of it from researching the radio itself.

Not that I can help with this issue, but I don't see an attached debug.log file.
