Re: ThumbDv and Windows 10
This is probably a problem with WinDV, which is supported by DUTCH*Star -- NW Digital Radio manufactures the hardware, but software support comes from the authors.
You can pull down ThumbTest.exe from https://nw-digital-radio.groups.io/g/ambe/files to test if your ThumbDV is communicating. If it passes this test, then the issue is not with the ThumbDV.
What you may wish to try is to remove all references to the DUTCH*Star software from the Windows Registry then reinstall.
