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:

1. Xiegu G90 Microphone Connector (8-pin RJ-45)
2. Headset with Microphone (e.g., gaming or aviation headset)
3. 3.5mm TRS (Tip-Ring-Sleeve) Jack for Headphones
4. 3.5mm TRS or TRRS Jack for Microphone
5. PTT (Push-to-Talk) Switch (Optional, can be foot pedal or inline switch)
6. Shielded Audio Cable
7. 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

1. Cut and Strip Wires: Prepare the audio cables and RJ-45 connector.
2. 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.
3. Insulate the Wires: Use heat shrink tubing to prevent shorts.
4. Test the Connections: Use a multimeter to check continuity.
5. 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.
