I have several radio's that have not been in service for a while. They're running 11.2 software and when I try to upgrade them to 12.1 or 13.1.3 I get an error message:
"Radio closed FTP connection FTP transfer files failed ....." This happens on several different radios. These radios have default configuration and I'm communicating with them on the Ethernet interface. Has anyone experienced this problem? Solution? Steve
