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:[[edit](https://freemwiki.com/index.php?title=Openai/67d4c7d0-e090-800a-a823-df0e8a3925a3&veaction=edit&section=4 "Edit section: Parts Needed:") | [edit source](https://freemwiki.com/index.php?title=Openai/67d4c7d0-e090-800a-a823-df0e8a3925a3&action=edit&section=4 "Edit section's source code: 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[[edit](https://freemwiki.com/index.php?title=Openai/67d4c7d0-e090-800a-a823-df0e8a3925a3&veaction=edit&section=5 "Edit section: Step 1: Understanding the Xiegu G90 Pinout") | [edit source](https://freemwiki.com/index.php?title=Openai/67d4c7d0-e090-800a-a823-df0e8a3925a3&action=edit&section=5 "Edit section's source code: 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[[edit](https://freemwiki.com/index.php?title=Openai/67d4c7d0-e090-800a-a823-df0e8a3925a3&veaction=edit&section=6 "Edit section: Step 2: Wiring Your Adapter") | [edit source](https://freemwiki.com/index.php?title=Openai/67d4c7d0-e090-800a-a823-df0e8a3925a3&action=edit&section=6 "Edit section's source code: 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)[[edit](https://freemwiki.com/index.php?title=Openai/67d4c7d0-e090-800a-a823-df0e8a3925a3&veaction=edit&section=7 "Edit section: Wiring for the Microphone Input (Mic Jack)") | [edit source](https://freemwiki.com/index.php?title=Openai/67d4c7d0-e090-800a-a823-df0e8a3925a3&action=edit&section=7 "Edit section's source code: 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)[[edit](https://freemwiki.com/index.php?title=Openai/67d4c7d0-e090-800a-a823-df0e8a3925a3&veaction=edit&section=8 "Edit section: Wiring for PTT (Push-to-Talk)") | [edit source](https://freemwiki.com/index.php?title=Openai/67d4c7d0-e090-800a-a823-df0e8a3925a3&action=edit&section=8 "Edit section's source code: 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[[edit](https://freemwiki.com/index.php?title=Openai/67d4c7d0-e090-800a-a823-df0e8a3925a3&veaction=edit&section=9 "Edit section: Wiring for the Headphone Output") | [edit source](https://freemwiki.com/index.php?title=Openai/67d4c7d0-e090-800a-a823-df0e8a3925a3&action=edit&section=9 "Edit section's source code: 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[[edit](https://freemwiki.com/index.php?title=Openai/67d4c7d0-e090-800a-a823-df0e8a3925a3&veaction=edit&section=10 "Edit section: Step 3: Assembling the Adapter") | [edit source](https://freemwiki.com/index.php?title=Openai/67d4c7d0-e090-800a-a823-df0e8a3925a3&action=edit&section=10 "Edit section's source code: 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[[edit](https://freemwiki.com/index.php?title=Openai/67d4c7d0-e090-800a-a823-df0e8a3925a3&veaction=edit&section=11 "Edit section: Step 4: Testing") | [edit source](https://freemwiki.com/index.php?title=Openai/67d4c7d0-e090-800a-a823-df0e8a3925a3&action=edit&section=11 "Edit section's source code: 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[[edit](https://freemwiki.com/index.php?title=Openai/67d4c7d0-e090-800a-a823-df0e8a3925a3&veaction=edit&section=12 "Edit section: Optional Enhancements") | [edit source](https://freemwiki.com/index.php?title=Openai/67d4c7d0-e090-800a-a823-df0e8a3925a3&action=edit&section=12 "Edit section's source code: 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[[edit](https://freemwiki.com/index.php?title=Openai/67d4c7d0-e090-800a-a823-df0e8a3925a3&veaction=edit&section=13 "Edit section: Alternative: Buy a Pre-Made Adapter") | [edit source](https://freemwiki.com/index.php?title=Openai/67d4c7d0-e090-800a-a823-df0e8a3925a3&action=edit&section=13 "Edit section's source code: 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.
