There's a simple fix for this. Go into Windoze Control Panel, open the "Sounds and Audio Devices" setup screen, click on the "Sounds" tab, and select "No Sounds" for the Sound scheme. Click OK and you've slain that dragon. >Just connect the line-output from the sound card to the line-input of the >K3 (note that the K3 line-input is a mono jack) and connect the line-output >of the K3 to the line-input of the sound card, and you are done with >connecting your computer to the K3.

I've always used the sound card built into my Thinkpad laptops for PSK, RTTY, and to play voice messages for SSB contests. Works fine. See my tutorial/app note on Ham Interfacing for simple wiring methods to avoid hum, buzz, and RFI. http://audiosystemsgroup.com/HamInterfacing.pdf There's nothing WRONG with using a Signal Link or something like it, but it is money you don't need to spend if you follow the simple directions in my tutorial. 73, Jim Brown K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
