[Elecraft] Fw: homebrew KX3 electret microphone
From: lmarion Sent: Saturday, October 25, 2014 6:52 PM To: Subject: homebrew KX3 electret microphone I am trying to make a KX3 microphone, no up/down. Just PTT with MIC bias. 1) do I need 4 ring jack, or will a 3 ring work? 2) which jack ring is used for the MIC bias?

Re: [Elecraft] Fw: homebrew KX3 electret microphone
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
