Hi
Windows 10, starting with build 1903, provides the option to disable access to your Microphone to desktop applications, use Winkey+I, Privacy, Microphone, then scroll down in the RHS pane until you see "Allow desktop apps to access your microphone",
Despite the description of "Microphone", this setting also affects the "Line" input which is used for I/Q input to the G8JCFSDR. If this setting is set to
OFF, then when U click the power on button in the G8JCFSDR U will get the dreaded Run-time error '-2147467259 (80004005)'? message, and yet all the usual diagnostic tests, eg DXDiag.exe will say that your audio device(s) is/are working correctly. I recently worked with John Coulter - thank you John - to track down why he was getting this error message despite all the signs that his PC's h/w was working correctly and we finally tracked down the problem to this "new and improved" privacy setting !
So please make sure that you have "Allow desktop apps to access your microphonr" set to
ON.
