JSS-2500 MF/HF 500W

The JRC JSS-2500 MF/HF 500W is a marine MF/HF radio installation. It is normally installed at the bridge radio console with external antenna, tuner and earthing/counterpoise system. It is designed for long-range voice and distress/safety communication beyond normal VHF range. The operating principle relies on MF/HF radio transmission and reception, with DSC where fitted/approved. The supplied entry gives no additional verified capacity, pressure, power or dimensional figure for this model. Compared with neighbouring models, the relevant differences are transmitter output, antenna tuner, control unit and GMDSS interfaces; these must be confirmed from the installed documentation rather than inferred from the model designation alone. Service and survey attention should concentrate on transmit/receive checks, tuner/antenna/grounding, cooling, identity/position inputs and power. For exact ratings, dimensions, tolerances, test limits and model-specific settings, refer to the manufacturer documentation for the exact figure.
