The Icom HM-180 is a ruggedized, heavy-duty hand microphone manufactured by Icom Inc. in Japan. Purpose-built as a primary or replacement microphone for Icom commercial marine HF SSB radiotelephones and land-mobile HF transceivers, the HM-180 provides clear voice transmission across long-range GMDSS and commercial maritime radio communication links.

Constructed from impact-resistant polymer housing, the HM-180 features an ergonomic side Push-to-Talk (PTT) switch and a high-clarity microphone capsule tuned to minimize background engine room and cabin noise. The unit comes equipped with a heavy-duty coiled cable, strain relief boot, and an 8-pin metal connector for secure lock-in attachment to radio front panels.

Key Features:
• Heavy-Duty Construction: High-impact ABS composite housing engineered for tough maritime and commercial bridge environments.
• Ergonomic PTT Operation: Large, positive-action side Push-To-Talk button allows easy operation even when wearing work gloves.
• Speech-Optimized Audio: Microphone element tuned specifically for voice clarity, reducing ambient bridge and background vessel noise during HF/SSB transmissions.
• Heavy-Duty Coiled Cable: Flexible, high-durability coiled cord with reinforced strain relief prevents tangling and cable fatigue.
• Secure 8-Pin Metal Connector: Screw-lock 8-pin connector ensures reliable electrical contact and prevents accidental disconnection under heavy vessel vibration.
