SKU CH-Q3NZ-V8EFS

Covert acoustic tube earpiece with PTT microphone for Motorola GP340, GP328 and GP1280 radios

  • Compatible with Motorola GP340 GP328 GP1280 radios
  • Covert acoustic tube keeps conversations private
  • Integrated PTT microphone enables hands-free operation
  • Radiation-proof design reduces electromagnetic exposure

Compatible Radio Models

This internal power cable is designed for Motorola GP340 GP328 GP1280 two-way radios. It provides the electrical link between the radio chassis and the headset or accessory module. Installers and radio technicians use it when building or repairing covert acoustic-tube headset kits. The part matches the pin-out and voltage requirements of the listed models.

Sustained Load Behaviour

Under continuous transmit cycles the cable maintains stable current delivery without voltage sag that would distort the push-to-talk microphone signal. The insulation resists heat build-up inside the radio housing during long shifts. Connectors stay seated despite vibration from vehicle mounts or body-worn use. The assembly is not rated for high-voltage applications beyond the radio’s native supply rail.

Questions about this item

Does the headset draw power from the GP340 battery all day?

The acoustic tube earpiece is passive; it uses the radio's own microphone and speaker circuits so no separate battery is needed.

Which Motorola two-way radios must I already own for the GP328 connector to fit?

The plug is moulded for Motorola GP340, GP328 and GP1280 models; other radios will not accept this connector.
