Folks, this should be my final post here on this but I think the information applies to any of us who use the K3s Codec with WSJT-X, maybe AFSK too, I haven't researched that possibility.
A brief recap to the issue at hand: The only way I could get WSJT-X to get the K3S to transmit was if I selected the K3s codec as default in windows. Doing so transmitted computer/internet generated sounds along with the WSJT-X signal. - Doing the procedure below will resolve this issue. Thanks to Peter, VK4JD who does not use WSJT-X for pointing this obscure setting out to me. How difficult my signal was, and maybe yours unknowingly to you, has to be to decode.. Peter's suggestion below is perfect. I wanted to find out the easiest way to demonstrate this windows "feature". Here is a URL that describes how to find this page in windows 10. Not sure about earlier versions of windows, I only have 10 now. https://tinyurl.com/y7dc57vm Now... Something I discovered: you must have WSJT-X running to see the option in this windows page! When I went to the page, WSJT-X was not showing and then I realized I was not running it. I use Win4K3Suite so I started that and then started WSJT-X. Moments later the WSJT-X sound ap was showing. Here is what it looks like in win 10: http://doctorgary.net/ap-vol-dev-pref.jpg When Peter's suggestion below led me to this windows page, the WSJT-X output and input were the windows default output and input. I selected the USB codec and that is what immediately stopped the K3s from sending out superfluous audio with my WSJT signal. To be sure, both the WSJT-X and audio from the computer were being sent out simultaneously. Not windows sounds, those have been off from day 1. I'm talking about any sound from any web page or audio ap that may be running without you hearing it. In this case that caused me issues with WSJT-X and the K3s, it was a youtube video that was playing & I didn't know it. I am posting this information to the WSJT-X list but since it dealt with the K3s, this answer also belongs here. Perhaps it is the same with any external card you use, as in the K3 with external digital soundcard? Hope you check your windows setting, you might be surprised. 73, Gary KA1J > Peter, > > Absolutely brilliant!
