[Elecraft] FT8 using internal USB sound on the K3S

Mon Jun 25 11:39:18 EDT 2018

You mean that in WSJT-X's Settings window under the Audio tab, it won't let
you select the K3S's USB Audio Codec for input or output? That's not how I
read your message, but if that is the case, then you may have fallen victim
to a recent Windows 10 "improvement".

In the Windows 10 Settings window, choose Privacy. Then on the left side,
choose Microphone. A setting called "Let apps use my microphone" should
appear. Turn this to On. If this is the problem, turning this option to On
should permit WSJT-X to get access to the sound card again.
