Where goes the PTT switch?

 

I see the Orange, #5 wire from the Microphone socket to the Raduino and the violet#1 and blue #2, also - but no switch.? Maybe it's in the microphone wires, that aren't shown?? If so, please tell me which wire.
I guess this is common knowledge because no one else has had this problem.? One other problem is about the pinout of the TRS sockets.I don't know which pin is the tip or ring or sleeve. I? followed the photos
but then I think someone mentioned that the text directions are different than the photo.? I'm confused. Thank you for your help.
My sincere gratitude to Ashhar for this miracle. I consider this the Holy Grail of QRP rigs!
Tnx and 73,? larry KA7ILH
 

The supplied jack assumes that you will have a? 3.5MM stereo plug for the mike/PTT connections.? Use??shielded wire for the mike connections that has two wires in the shield.??If you are using the supplied microphone cartridge, you attach the outer case of the mike (small metal connections running from the solder pad to the case) to the tip connection of the plug via one of the center conductors of the shielded wire.? The other solder pad attaches to the sleeve connection through the shield of the wire.? One side of the PTT switch goes between the ring? connection of the plug while the other side attaches to the shield connection at the mike.
 

Hi Dennis,?? That's? a fine drawing.? How did you do that? Thank you. Could you please do one

like that of a TRS socket with the pins named and numbered?

OR, simpler yet,? just point me to a link.? I've spent hours Googling but failed. - surprisingly !

Thank you, Dennis.? I'm nearly done with the wire-up.? Shud finish tomorrow - w/your help.

Tnx agn.?? 73?? larry

This should do it:

Dennis,

I think this depends on how your mic is wired. This is the way mine is wired.?image1.jpeg

Joel:

Same here!! From a QRP Quarterly article I wrote. The switch Ashhar includes friction-fits in a hole and the wire is old telephone wire.

Joel,

Read the previous posts in this thread and you will see why the jack is laid out in this manner.
