Re: Aircraft headset speaker impedance and ubitx #ubitx

I see no reason why the electret mic should not be satisfactory but I have my doubts on the 600 oh impedance head phones.The uBITX requires 8 ohms to around 32 ohms to match most earphones.I suspect that you would get very little output into 600 ohms.

Thank for letting me know. I'll try to measure my actual headset speaker impedance to be sure of that.
