No worries what so ever. All of the FLEX-6000 are FULLY supported by our tech support, repair service, and software development teams. The only thing with the FLEX-6300 and FLEX-6500 is we are no longer manufacturing them, we didn't abandon them.
As a case in point, the FLEX-5000 was discontinued 7 years ago. We still provide tech support and repair services for the radio. And even though we are no longer releasing PowerSDR, we fully support KE9NS in all his software endeavors and work with him to maintain updated TURF files for those radios.
