Good Morning, Hans,

Your microphone has four leads, which in fact are two screened leads. With a multi-meter identify the PTT switch lead and its screen. The data sheet does not seem to contain a schematic of the microphone, but you should be able to identify the PTT switch, as it will show a short circuit when the yellow button is pressed.

The other lead is the microphone connection. Connect the screen of the microphone lead and the screen of the PTT lead to the shield of a 3.5mm Tip-Ring-Sleeve (TRS) plug. Connect the signal of the microphone lead to the tip, and the PTT lead to the ring of the plug. That's it.

The microphone will be fed with a bias voltage via a current limiting resistor in the TRX2, and electret microphones are uncritical as to the exact voltage, so that should work fine.

Let me know if you need any further assistance.

Thank you very much Adrian,

This is my first electret microphone I intend to use. I read in reviews, that the Piker supposingly is a very good one. And it was a pin-in-the-butt to purchase it.

I keep you updated. I hope not asking to stupid, maybe for you obvious issues.
