AIS Transponder · Navigation & Bridge Equipment
The Weatherdock easyTRX3-IS is an AIS transponder. It is normally installed on or near the bridge with VHF/GNSS antennas and bridge data interfaces. It is designed for automatic exchange of vessel identity, position, course, speed and voyage information. The operating principle relies on periodic AIS data transmission and reception over marine VHF channels. Compared with neighbouring models, the relevant differences are transponder class, sensor interfaces, display functions and antenna arrangement; these must be confirmed from the installed documentation rather than inferred from the model designation alone. Service and survey attention should concentrate on own-ship data, GNSS/heading inputs, target reception, antenna system and bridge interfaces. 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.
