Re: Mic wire up?

Ian Reeve

That doesn’t sound correct.

It should be tip to mic +

Ring to PTT

Sleeve should ground other mic connection and other ptt connection.


Hope this helps

Subject: [BITX20] Mic wire up?
Hi all. New uBitX owner trying to sort things out. It turns on, has volume and VFO working.  It won't transmit, so I'm starting with one question at a time.

Is my mic wired up correctly? There was little info in the "wire up" on HF signals so I wired it in series, the tip goes to the side of the mic with traces, and then to PTT which is soldered to the ring of the plug.  Is this right?

Thanks! Steven KM4WIP
