Howard, Here is the?KobiConn parts number?from Mouser:? 161-5435-EX As a TRRS Jack the following?pinout is expected.? See PDF drawing attached. Pinout: Contact A is Tip Contact B is Ring 1 Contact C is Ring 2 (no contact - unless you want to wire as a TRRS Jack for a standard CTIA TRRS Headset) Contact D is Sleeve (the longest Terminal) If?you want to wire it for the CTIA TRRS Headset (US Standard and most of the ROW) then? Sleeve is MIC+ (yes, that's correct) Ring 2 is Headphone Common and Mic- Ring 1 is Right Headphone Tip is Left Headphone Then you could run VOX with the TRRS headset. Or add a second Jack wired: tip to PTT, Sleeve to?Ground. It takes plenty of force to seat it completely, but it won't fall out on its own. 73 Dave WI6R On Wed, Mar 26, 2025 at 5:15?AM Howard Lamhut via <Howardlam=[email protected]> wrote:
