[Elecraft] KX3 Mic alternative

[Philip Godbold]

Reading the list with respect to adding an internal mic - there is an easier option.

Take a 90 deg 4 pole mic plug and mount an electret insert inside.

Method

Open the plug cut the cable strain relief down to about 2.5mm  1/10 inch remaining from the end of the plug

Mount the electret insert behind this, inside of the plug.

Wire to ground and mic

Put a tiny piece of sponge in the end of the strain relief, close the plug.

You now have a miniature mic to use with VOX - it works !  

You can turn the mic to the direction required and it takes the minimum of space, you can even leave installed ready to use.

I have a picture available if needed.
