I am planning to build a headphone splitter/switch so I can listen to
one K3 in the left ear and the other radio in the right ear or turn off
the audio from either radio.
Two questions:
Is there a commercial item for this purpose?
I know I will need an audio isolation transformer between each radio and
the splitter/switch. Any suggestions on what a good impedance value
would be for those transformers?
Thanks
