The Samyung SM-1150 is the standard Handset/Microphone used for the Samyung SRG-150DN and SRG-250DN MF/HF GMDSS radio systems. It is designed for high-durability maritime use, featuring noise-canceling technology to ensure clear communication in loud engine room or bridge environments.

The SM-1150 is a palm-type microphone/handset that connects directly to the front panel of the SRG-150DN transceiver. It utilizes a multi-pin circular connector and is built to GMDSS (Global Maritime Distress and Safety System) standards.

• Function: Handles Push-to-Talk (PTT) voice transmission.

• Controls: Typically includes PTT (side switch) and sometimes UP/DOWN channel selection buttons on the top or side.

• Audio Quality: Employs digital filtering and noise-suppression logic (when paired with the SRG-150DN’s DSP) to eliminate ambient ship noise.
