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.

Hi to you 2

What Mikrofon do you recomment for the TRX2A Adrain?

Hi Daniel,

I use a boom microphone headset. Several work nicely with the Jume TRX2, my particular favourite is the EPOS H3, but I have also used the Yamaha CM-500, the Audio-Technica ATH-PDG1a, and the Austrian Audio PG16. I much prefer to use a headset as the transceiver is somewhat microphonic and with the speaker volume turned up this can lead to feedback. In order to use these headsets you will have to make yourself a little patch box to bring the rear speaker connection round to the front, as well as to have a push button for the PTT switch.

Many of these gaming headsets now use the Tip-Ring-Ring-Sleeve (TRRS) plug wired to CTIA standards, and you will need a 'Y' adaptor that converts this to a Tip-Ring-Sleeve (TRS) 3.5mm stereo plug for the headphones, and a similar plug for the microphone. The EPHOS H3, Audio-Technica and Austrian Audio headsets came with this cable.

Because the microphone is designed to provide an equal level right and left input to a standard stereo microphone input, both the tip and the sleeve are common. The patch box will need to be wired so that the microphone input to the TRX-2 has the microphone connected to the tip and the ring connected to the push button PTT switch and the sleeve connected to ground.

The Elecraft MH3 microphone intended for the KX3 transceiver can also plug straight into the TRX-2 and work.
