Icom HM-200B Marine Speaker Microphone for M324 & M324G

Description

Genuine OEM IPX7 Waterproof Marine Hand Speaker Microphone

Original equipment replacement palm microphone featuring channel controls, durable coiled cable, and Molex connection for Icom IC-M324 fixed-mount VHF transceivers.

The Icom HM-200B (catalog part HM-200B / HM200) is an authentic original equipment manufacturer (OEM) marine hand speaker microphone designed specifically for Icom fixed-mount VHF maritime transceivers. Engineered as the direct factory replacement for the microphone originally supplied with the IC-M324 and IC-M324G radios, this palm mic restores crystal-clear voice modulation and dependable Push-To-Talk (PTT) operation. Whether replacing a unit worn by salt spray, damaged by severe offshore weather, or lost during vessel refits, the HM-200B delivers factory-grade acoustic clarity and instant channel navigation from the helm.

Built to withstand demanding nautical environments, the Icom HM-200B features an IPX7 submersible waterproof rating, capable of surviving temporary submersion in one meter of water for up to 30 minutes without seal failure or audio distortion. The ergonomic housing incorporates tactile channel UP and DOWN buttons alongside high/low transmit power and emergency Channel 16/9 access controls, allowing captains and crew to manage radio functions without reaching for the main radio console. Terminating in a heavy-duty, corrosion-resistant Molex connector with an industrial-grade coiled lead, the HM-200B operates in full compliance with maritime FCC Licensing standards to keep vessel communications dependable offshore.
