The Heil AD-1-K adaptor works fine on a K3S with my electret mic so no adaptor modification should be needed, unless yours is defective. As others have said, you can try the back mic jack.

I believe the ModMic is electret - requiring BIAS, which I know is turned on at CONFIG > MIC > press #2, so the end result is FP.H BIAS. A Heil AD-1-K is plugged into the front panel; however, pin 6 (8v) is not wired to the mono 1/8 mike jack on the adapter. The Modmic uses a T-R-S 1/8 inch. What is the correct pinout for the K3 front mic jack to the Modmic? --Scott, W5WZ ______________________________________________________________ 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
