Hi,
My radio was working but I did a clean install of the software and removed the user %appdata% directory and installed the latest 1.0.3 version of the software.

The band data does not switch my SPE. It turns the amp on and off but switching bands is not working via BAND DATA. I have set the band data in the software.

Any advice?

I fixed it by restoring the user Expert directory that was in my windows rubbish bin. It is working now. So there must be an issue with the latest version of 1.0.3.
