Re: Aircraft headset speaker impedance and ubitx #ubitx
I would say your deduction is correct as regards the Jack plugs. The one where you measure the 63 ohms is the headset,the mic if electret should measure as a open circuit.Does each Jack plug just have two connections,the tip and sleeve?

I've tested the headset and the resistance which is not really the impedance seems to be 63 ohms on the 6.35 mm jack. I guess the 6.35mm jack is for speakers and the 5mm for the mic.
Could you please confirm that?
