Most of the The "Flex" radios rely upon a computer, do they not? And when (not if, but WHEN) Microshaft goes beyond Windoze 10, will it still be supported? Or ANY operating system, (Windoze, LINUX, etc.) have support, and just WHO will support it, and for how long? I still use transceivers built even before computers were commonplace (DOS 3.2 or earlier come to mind) that would be mere doorstops if they relied on a computer, yet they are still totally functional. Can THAT be said for the FLEX offerings 10 or 20 years down the road?
