VHF DSC Radio · GMDSS
The Sailor 6248 VHF DSC is a marine VHF DSC radiotelephone. It is normally installed at the bridge GMDSS/radio console with VHF antenna and position input. It is designed for routine VHF voice traffic plus digital selective calling for distress and safety functions. The operating principle relies on VHF voice communication combined with DSC calling and identity/position data. Compared with neighbouring models, the relevant differences are DSC controller, remote stations, AIS integration and approval configuration; these must be confirmed from the installed documentation rather than inferred from the model designation alone. Service and survey attention should concentrate on voice and DSC tests, MMSI/position input, antenna condition, distress controls and emergency power. For exact ratings, dimensions, tolerances, test limits and model-specific settings, refer to the manufacturer documentation for the exact figure.
What our service work and the manufacturer documentation say about keeping this model running.
Carry out the permitted operational/self-tests, inspect antennas, feeders, connectors, controls and cooling, and verify normal and emergency power where required. Check vessel identity, position and interfaces appropriate to the equipment type and review recurring alarms or logbook entries. A radio surveyor should confirm the installation and programmed data against the approved radio documentation.
Carry fuses, approved handsets/microphones or control accessories where applicable, antenna connectors and feeder repair items, selected power-supply components and manufacturer-recommended interface/control spares. The spare scale should match the vessel's declared GMDSS maintenance method.
