    Wired remote access microphone for compatible Standard Horizon VHF radios, giving helm stations full radio control, AIS viewing, and DSC access from a second location.

    Designed for Standard Horizon GX1800, GX1800G, GX1850, GX1850G, GX2400, and GX6000 radios, this wired remote microphone extends control to wherever it’s needed on the boat. The unit includes a 23-foot cable for flexible placement at the helm or another working station. Its IPX8 waterproof rating supports submersible use, and the display is built for easy reading in bright marine conditions. The SSM-70H is not backwards compatible with other Standard Horizon models.

    • Controls the main radio’s functions from a remote station for faster access at the helm.
    • Supports up to 2 RAM4 wired remote stations for multi-point operation.
    • Includes intercom communication between the radio, RAM4, and Wireless RAM4W microphones.
    • Shows AIS targets on a larger high-resolution display with bright backlight.
    • Provides DSC functions including individual calling, group calling, and position polling.
    • Supplied with a 23-foot routing cable for practical installation options.

    Use this remote microphone when the main radio is mounted away from the person running the boat. By placing controls closer to the helm, it reduces back-and-forth movement while keeping key radio functions within reach.

    The rotary channel and volume controls make everyday adjustments straightforward, while programmable hot keys help speed up menu access. The waterproof design and 3-year waterproof warranty add confidence for marine environments where spray and exposure are common.

    This model is intended for select Standard Horizon radios and should be matched to compatible systems before installation. For boats that rely on frequent calling, AIS monitoring, and DSC operation, it adds a dedicated remote interface without changing the main radio location.
