Noob without mic

[email protected]
 

So the ubitx comes with an electret mic, a pushbutton, and some extra resistors.? I guess it¡¯s pretty obvious these are to build the mic with.? But where are the directions or a schematic for the mic itself?

Secondly, does a mic need to be plugged into the jack to be able to hear audio?? Can you use headphone? I believe I got in over my head this time.

Thanks, but that doesn¡¯t show how to wire it up for an idiot like me.

Ground is common to tip and ring.? Switch goes between ring and sleeve

Best to use shielded wire for mic lead.

I have a lot of positive comments on the audio quality with both my bitx40 and ubitx.? I am using stock mikes.?
 

Here's a sketch with a picture. No resistors needed, just the electret and the switch

I prefer to wire the mic to the ring and the PTT to the tip.? That way the mic won¡¯t be exposed to PTT voltage as the plug is inserted and removed from the jack.
