Greetings to all. I would like to operate a Telex 750 aviation headset formerly used in my past life.My goal is to use the headset for hands free ops at the shack and future mobile/portable ops. There are two male plugs, one 3.5 mm plug (mono) for the headphone side and the other a ¼” plug (stereo) for the microphone.The mic is an electret type. Impedance info states that it is between 15-600 ohms.Fortunately, both male plugs are still installed.I plan on connecting through to a female stereo plug, then connected to the K3’s front panel eight pin connecter. Anyone having step by step installation experience with would be appreciated.
