I am a ham radio operator.  I'm trying to use the notebook for digital communications.  It has a combination mic/headphone jack.  In order to connect my digital interface I need to know the pinout of the jack.  I've found several different pinouts of plugs on the internet, all different!

 

Thanks in advance,

    I believe the combination jack is a 3.5mm 4-connector TRRS

    Your's might be completely different. Hope this helps

    Thank you for your reply!  That is one of the iterations I came across when searching the internet.  I have the 3 ring +tip plug and splitter cable.  It would be simple to just plug them into the radio to see what works, where.  But (and there's always a but) each one has a different connector at the radio.  I have rung out the cable and plug which is fine but which is which.
