Chen has given good advice here, but all jacks on the back of the K3 are mechanically stereo jacks.
In the case of line-in, only the tip has an electrical contact (which makes it mono electrical input). So it is convenient to just use a manufactured stereo 3.5mm plug to 3.5mm plug cable to connect from the computer sound card to the K3. Only the left channel from the computer soundcard can be heard by the K3, so make sure your application puts its audio out only the left channel (most do). BTW - you *can* use the EMU202 soundcard for both LP-Pan and digital modes, *but* not at the same time. Using digital modes, one usually has a waterfall display showing the spectrum of interest, and IMHO, the panadapter display is superfluous during those periods, your mileage may vary on that point. Using the default computer soundcard is only a problem if you are trying to use VOX - windows sounds, should they occur will be transmitted as a SSB signal. If you are using PTT generated by the PSK31 application, that problem is not present. Another soundcard is the easiest answer to many potential problems. 73, Don W3FPR Kok Chen wrote: > 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) > ______________________________________________________________ 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
