Making a headset adapter for a Xiegu G90 radio requires some soldering and understanding of the pinout of the radio’s microphone and headphone jacks. Here's how you can do it:

===== Parts Needed: =====
# Xiegu G90 Microphone Connector (8-pin RJ-45)
# Headset with Microphone (e.g., gaming or aviation headset)
# 3.5mm TRS (Tip-Ring-Sleeve) Jack for Headphones
# 3.5mm TRS or TRRS Jack for Microphone
# PTT (Push-to-Talk) Switch (Optional, can be foot pedal or inline switch)
# Shielded Audio Cable
# Heat Shrink Tubing & Soldering Tools

===== Step 1: Understanding the Xiegu G90 Pinout =====

The RJ-45 Mic Connector Pinout (for the stock microphone) is:

| Pin | Function |
| --- | ------------------- |
| 1 | UP Button |
| 2 | DOWN Button |
| 3 | MIC (Audio In) |
| 4 | GND (Ground) |
| 5 | PTT (Push to Talk) |
| 6 | +8V Power (for Mic) |
| 7 | NC (Not Connected) |
| 8 | GND (Ground) |

The headphone output on the G90 is a standard 3.5mm TRS jack, which provides mono audio.

===== Step 2: Wiring Your Adapter =====

You'll need to connect your headset mic and headphones to the Xiegu G90 via an adapter that plugs into the RJ-45 mic jack and the 3.5mm headphone jack.

====== Wiring for the Microphone Input (Mic Jack) ======
* Tip → MIC (Pin 3 on RJ-45)
* Ring → PTT control (Pin 5, through a switch)
* Sleeve → GND (Pin 4 or Pin 8 on RJ-45)

====== Wiring for PTT (Push-to-Talk) ======
* Connect Pin 5 (PTT) to Ground (Pin 4 or 8) via a switch (such as a momentary push button or foot pedal).

====== Wiring for the Headphone Output ======
* The 3.5mm TRS headphone jack should be wired as follows: - Tip → Speaker Audio (Mono) - Ring → (Leave Disconnected) - Sleeve → Ground

If using stereo headphones, you might need a mono-to-stereo adapter to get sound in both ears.

===== Step 3: Assembling the Adapter =====
# Cut and Strip Wires: Prepare the audio cables and RJ-45 connector.
# Solder the Connections: - Connect the mic input to the RJ-45 Pin 3. - Connect PTT switch between Pin 5 and Pin 4 (ground). - Connect the headphone jack to the G90's 3.5mm output.
# Insulate the Wires: Use heat shrink tubing to prevent shorts.
# Test the Connections: Use a multimeter to check continuity.
# Assemble the Housing: If using a project box, secure the components inside.

===== Step 4: Testing =====
* Plug the RJ-45 into the G90 mic port.
* Connect the headphones to the G90 audio out.
* Use a multimeter to check for any shorts or miswiring.
* Test transmit (PTT) and receive audio.

===== Optional Enhancements =====
* Add a Preamp if your headset mic requires more gain.
* Use a Foot Pedal PTT instead of a hand switch for easier operation.
* Include a Volume Control for headphone audio.

===== Alternative: Buy a Pre-Made Adapter =====

If you don’t want to DIY, some sellers on eBay and ham radio forums offer G90 headset adapters that allow you to use aviation or gaming headsets directly.
