--- - - - --- Steve, If you are going to be experimenting, then I suggest the Rework Eliminator(TM) K2 Internal Mic Adaptor (IMA). It supports jumper configurable wiring of the pin-out as well as seven jumper selectable bias resistances between 820 and 10k Ohms. All Alinco, Elecraft, Heil, Icom, Kenwood, Ten-Tec, and Yaesu 8-pin Foster microphone pin-outs are supported. And best of all, you don't have to disassemble the radio to change configurations! All that's required is removal of the left side panel! See http://www.unpcbs.com/#rework_eliminator_TM_products for a brief description, or visit http://www.unpcbs.com/adaptor/ for full details. 73, Gary KI4GGX (webmaster) ______________________________________________________________ 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
