Re: Aircraft headset speaker impedance and ubitx #ubitx

I have used aviation headsets a good bit with the ubitx and others and the speakers are usually 10-15 ohms. The 600 ohm will likely not work very well without a little audio step down transformer.  On the other had, the electret mic might work very well.

Subject: [BITX20] Aircraft headset speaker impedance and ubitx #ubitx #ubitx #ubitx
Hi everyone! 
I've ordered yesterday my ubitx and I'm thinking upon the boxing and peripherals to add. 

I already have a great quality tourism aircraft headset with mic and was thinking about using it with the ubitx to have comfortable equipment for my ears.

But the impedance of the speakers is 600 ohms. I've red that the IC audio output is for something about 8 ohms. So what should be the behavior with 600 ohms? Does it will work in your opinion or best : did someone already test it?

Thank you for your kind answers.
