The Icom SM-J1 is a commercial-grade desktop gooseneck microphone manufactured by Icom Inc. in Japan. Purpose-built for base station, coast station, and wheelhouse desk operations with Icom marine HF/VHF transceivers and commercial radio systems, the SM-J1 provides flexible positioning and clear, high-intelligibility voice transmission.

Featuring a multi-position flexible gooseneck stem mounted on a weighted desktop base, the SM-J1 is equipped with integrated Push-To-Talk (PTT) and PTT Lock switches for hands-free or continuous broadcasting during maritime watches. The microphone capsule is acoustically tuned for voice clarity, attenuating low-frequency ambient hum and vessel cabin noise across commercial bridge communication setups.

Key Features:
• Flexible Gooseneck Design: Allows precise, multi-angle positioning of the microphone capsule for ergonomic, hands-free operation.
• Integrated PTT & PTT Lock Switches: Features a responsive Push-To-Talk bar and a tactile lock button for continuous transmissions without holding down the switch.
• Speech-Optimized Audio Pickup: Dynamic/electret capsule engineered for maximum voice clarity and background noise reduction.
• Weighted Non-Slip Base: Heavy-duty base unit provides high stability on vessel chart tables, radio desks, and bridge consoles.
• Heavy-Duty Shielded Interface Cable: Outfitted with a durable noise-shielded cable terminating in a standard 8-pin connector for secure lock-in attachment.
