Go back and read the post I made two days ago on this topic. It tells you EXACTLY what to do. In short, tip to mic input, ring to 8V through a resistor in the 5K to 10K range. If you want to know more, see http://audiosystemsgroup.com/HamInterfacing.pdf and the tutorial on audio in an appendix of http://audiosystemsgroup.com/RFI-Ham.pdf 73, Jim 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
