You can plug the Yamaha CM500 microphone and headphone 3.5mm plugs directly into 3.5mm jacks on the back panel, and use the K3's SPKR+PH capability (which I have set up as PF1) to turn the speaker on and off. The K3 has a back panel RCA connector that you may use for something like a foot switch, if you prefer PTT.
If you prefer a front panel microphone/headset connection, the Yamaha CM500 comes with a 3.5mm to 1/4" phone plug adapter, and you can use something like the Heil Sound AD-1-K adapter (or a home-brew equivalent) that has an 8 pin foster plug, a 3.5mm jack for the microphone, and a 1/4" mono jack for a footswitch like the Heil Sound FS-3. I prefer to keep the footswitch connector on the back panel, even if I'm using a front panel headset. 73 de Dick, K6KR > Before I order the headset, I am curious as to what mic connector is provided if any? I am supposing an 8 pin connector is a required purchase for my K3, correct? > Griff...N5AG ______________________________________________________________ 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
