Ergonomically positioned PTT allows for easy operation. Includes a 3 ft, compact but durable auxiliary cable to connect the microphone to your transceiver. The textured, 3D printed black PETG housing provides a secure grip during operation. Sensitive electret mic element provides sufficient signal strength for the QMX.
