The JRC JSS-2500 is an ultra-high-power Class A MF/HF radio communication system engineered by Japan Radio Co., Ltd. for commercial vessels operating across GMDSS sea areas A2, A3, and A4. Built for maximum long-range signal reach, it delivers up to 500 watts of transmit power under AC operation, ensuring crystal-clear voice communication, Digital Selective Calling (DSC), and optional telex/NBDP data logging in harsh maritime environments.

Designed with a heavy-duty modular architecture, the JSS-2500 combines a compact controller unit, automatic antenna tuner, dedicated power supply unit, and an integrated 6-channel DSC watch-keeping receiver. By continuously monitoring all six distress and safety frequencies, it serves as an indispensable GMDSS safety lifeline for deep-sea merchant vessels, ocean tankers, and offshore platforms.

Key Features:
• 500W High Transmit Power: Provides maximum signal reach and transmission clarity across all maritime MF/HF bands.
• Integrated 6-Channel DSC: Continuously scans all standard GMDSS distress and safety frequencies simultaneously.
• Full SOLAS & IMO Compliance: Meets strict international regulations for Class A MF/HF radio station installations.
• High-Visibility Controller: 3.8-inch backlit LCD screen with 10 dimming settings, contrast controls, and custom user keys.
• Spring-Loaded Distress Activation: Protected emergency button prevents accidental activation while enabling instant alert broadcasts.
• Rack-Mount Power System: Designed with a dedicated heavy-duty power supply unit for reliable continuous full-power transmission.
