The system and transceiver plates both carry serial number BS82424. The main equipment plate also displays CMIIT ID 2010AJ5191 and model JSS-2150N.
The JRC JSS-2150N MF/HF Radio Equipment is part of Japan Radio Co., Ltd.'s marine communication product family. The JSS-2150 is designed for medium-frequency and high-frequency radiotelephone communication and Digital Selective Calling (DSC).
The equipment is used aboard ships for long-range maritime communication, including distress, urgency, safety and routine calls when correctly installed and commissioned.
The photographed arrangement includes an NTD-2150 transceiver, NCM-2150 operating controller, NFC-2150 antenna tuner and data-terminal equipment.
The modular architecture is useful to marine service engineers because individual components can be identified for troubleshooting and replacement.
SM MARINE SERVICE™ supports enquiries for complete JRC MF/HF radio equipment, compatible modules, internal electronic assemblies and international marine communication spare parts.

Original photograph showing JSS-2150N system identification, NTD-2150 transceiver type, serial number BS82424 and Made in Japan markings.
The photographed transceiver plate specifies compass safe distances of 1.2 m for standard compasses and 0.8 m for steering compasses.
These values belong to the NTD-2150 unit and should not be substituted for the compass safe distances marked on other system components.
The JSS-2150 is a maritime radio system that supports long-range communication over medium- and high-frequency radio bands.
It combines a transceiver, controller and automatic antenna tuner. Optional data-terminal equipment allows NBDP (Narrow-Band Direct Printing) communication where fitted and properly configured.
The system provides Class A DSC with dedicated watchkeeping on six internationally designated MF/HF DSC frequencies.
The JRC radio family also supports onboard self-diagnostic functions to help identify possible equipment faults.
GMDSS compliance note: The suitability of an individual JSS-2150 installation depends on the ship's sea area, required radio fit, approvals, commissioning and operational condition. The presence of DSC or NBDP equipment alone does not establish current regulatory compliance.

JRC publishes IMO-approved specifications for the model family |
These specifications are published by JRC for the JSS-2150 150 W model. They describe the product design, not verified operating measurements from the used equipment pictured.
The NTD-2150 is the primary transmitting and receiving unit of the system. It provides the RF communication functions and integrates with the operating controller and antenna tuner.
The pictured equipment is marked:
Model: NTD-2150
Serial number: BS82424
Manufacturer: Japan Radio Co., Ltd.
Made in Japan
Its connections include the watchkeeping/receiving antenna interface, grounding and the associated system connections.
NTD-2150 transceiver reference. The actual SM MARINE SERVICE™ equipment is shown in the original photographs.

The NCM-2150 provides the operator interface for the MF/HF system. It includes an LCD, keypad, communication controls and a protected distress-alert button.

The rear panel includes connections labelled EXT SP, EXT MODEM and PRN-C, together with other controller interface connections.
JRC documentation identifies the 7ZCJD0343 controller cable as a 5 m connection cable.

The NFC-2150 is the automatic antenna tuner associated with the 150 W JSS-2150 system.
It adjusts the matching arrangement between the transceiver and the installed transmitting antenna for supported operating frequencies.
JRC's published specification identifies the tuner as approximately 3.3 kg.
The tuner contains a designated matching assembly, CFG-2150, which is an important identifier when purchasing internal replacement components.
The original complete-set photograph shows an NDZ-327 DATA TERMINAL.
The supplied product notes refer to NDZ-227, which appears in JRC documentation for the NBDP option. However, the actual display marking in the photograph should take priority when identifying this particular unit.
The NDZ-327 must therefore be quoted as the photographed model. Its compatibility and installed NBDP configuration require separate verification.
An accompanying keyboard is visible in the complete-set photograph. The supplied product information identifies the NDF-369 keyboard family, but the keyboard's own type label should be checked before assigning that model to the photographed item.
The NQW-261 handset is part of the standard controller equipment identified in JRC's system documentation.
The handset permits voice communication through the MF/HF radiotelephone.
Buyers should verify the handset model and connector arrangement when ordering it separately.
The JSS-2150 system includes multiple repairable electronic assemblies. JRC's service documentation identifies the following repair-unit numbers.

These are documented component identifiers for the JSS-2150 equipment family. None should be described as an individually photographed or available PCB without checking actual board markings and stock.
The JRC JSS-2150 is used for marine MF/HF voice and DSC communications aboard suitably equipped vessels.
Relevant applications include ship-to-shore communication, vessel-to-vessel communication, distress and safety communications, DSC watchkeeping and optional NBDP radio telex operations.
Equipment in this category is commonly fitted aboard merchant vessels such as tankers, bulk carriers, container vessels and other SOLAS-class ships where the required communication arrangement calls for MF/HF facilities.
The exact GMDSS sea-area suitability must be evaluated against the complete approved radio installation.

These are possible fault categories, not a diagnosis of the supplied radio system.
A qualified marine radio technician should record the exact model, serial numbers and fault information before carrying out inspection.
The technician should verify the approved supply voltage, equipment connections, transceiver/controller communication and antenna tuner status.
JRC's self-diagnostic functions can assist fault investigation; results should be recorded and interpreted using the correct service procedures.
High-power MF/HF equipment may create dangerous RF voltages and radiation hazards. Do not touch antenna components or dismantle energized radio equipment. Distress-alert controls must never be operated casually for testing.
Inspect controller, transceiver and tuner enclosures for damage.
Check accessible cables and connectors for corrosion or wear.
Record power supply and equipment status during maintenance.
Test MF/HF communication functions using approved procedures.
Check DSC watchkeeping and related indications.
Inspect antenna tuner mounting and cable condition.
Preserve equipment configuration and installation records.
Use correctly identified replacement units and PCB assemblies.
Arrange appropriate GMDSS radio inspections and operational tests.
The photographs show cables with exposed conductors around the equipment. These should be treated as requiring inspection and proper termination before any commissioning or electrical test.

MF/HF systems continue to provide important long-range maritime communication functions and are used as part of approved ship communication arrangements.
For ships already equipped with a JSS-2150 installation, compatible replacement modules may help maintain the original system without extensive changes to established wiring, antenna components and operator arrangements.
A suitable replacement must still meet the ship's current communication and regulatory requirements. Existing model compatibility does not automatically guarantee approval of a replacement installation.
It is a 150 W MF/HF marine radio equipment system supporting radiotelephone communication and Class A DSC.
JSS-2150N is the model designation visible on the supplied system's equipment nameplate.
It is the main MF/HF transceiver unit used in the JSS-2150 system.
It is the MF/HF operating controller used to manage communication functions.
It is the automatic antenna tuner associated with the JSS-2150 transceiver system.
Yes. JRC documentation confirms Class A DSC and six-channel DSC watchkeeping.
An NBDP configuration is available with the appropriate data-terminal and accessory equipment.
They should not be assumed identical. The photographed display is marked NDZ-327, while NDZ-227 is identified in the supplied information for another documented NBDP configuration.
