You don't need a TRRS plug. You can use a TRS plug. Mic hot lead to the Tip. PTT to the Ring. Ground on the Sleeve.
Then, in the Menu, set MIC BTN = PTT. This turns the Mic Button feature off. Mic bias is applied to the mic lead on the tip - no separate connection. See the schematic on the Elecraft website. <http://www.elecraft.com/K2_Manual_Download_Page.htm#KX3> Cheers, David/KG6IRW -- View this message in context: http://elecraft.365791.n2.nabble.com/Fw-homebrew-KX3-electret-microphone-tp7594194p7594195.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ 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 Message delivered to arch...@mail-archive.com
