Unless I am missing something in your description, the only hardware you need is a single stereo patch cable (one with 3.5 mm stereo plugs on both ends) from the stereo Line Out jack on the K3 to the stereo Line In jack on a standard 2-channel sound card. If your sound card has only a mono input, use a different sound card (one with stereo inputs). In the Windows setup for the sound card, make sure it is configured for two channels.
The main RX audio will be recorded in the left channel and the subRX audio will be recorded in the right channel of the stereo recording. Transmit monitor audio will appear in both channels. On playback through headphones, you will hear the main RX in your left ear and the subRX in your right ear. For dual-RX RTTY with the identical hardware, run two separate copies of your RTTY program(s), one copy configured to use the left channel of the sound card (for the main RX) and the other copy configured to use the right channel of the same sound card (for the subRX). 73, Rich VE3KI K7HP wrote: I [...] have not figured a way to record the SUB rx output at same time unless I made some sort of external circuit xfmr or resistors to feed LINE OUT tip and ring to a single input Maybe there is something I am missing ? This would also allow decoding RTTY from either MAIN or SUB rx . ??? ______________________________________________________________ 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]
