QMX 3D-Printed Microphone – Limited Stock

Designed and printed by Scott Baker, this compact and lightweight 3D-printed microphone is specifically created for use with the QMX ham radio, offering a practical and portable solution for voice operation.

The microphone features a clean, ergonomic design with a durable 3D-printed enclosure, making it ideal for both portable and home setups. Its small form factor ensures easy handling while maintaining reliable performance during operation.

Equipped with a 3.5mm TRS connector, the microphone follows the standard pinout:

Tip (T): PTT (Push-To-Talk)
Ring (R): Microphone
Sleeve (S): Ground

This makes it not only compatible with the QMX, but also with other radios that use the same 3.5mm TRS microphone configuration.

The unit is fully assembled and ready to use, requiring only a standard 3.5mm stereo audio cable (not included) for connection.
