"That leads me to believe that the K3 output is rapidly changing on and off"
I have not looked at the video but this sounds very similar to a problem I have seen. In my case HDSDR sound output had spontaneously changed to TS-590 TX CODEC creating a feedback loop through the PC. Break the loop and all is normal. 73, Andy, k3wyc ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
