It was my second attempt and but this time my report of a DSC transmission by CGTM Mar del Plata, Argentina on 8414.5 kHz was confirmed. I sent my report to mpla(at)prefecturanaval.gob.ar .
CGTM stands for Centro de Gestión de Tráfico Marítimo (Maritime Traffic Management Center). It is part of the Prefectura Naval Argentina (PNA). The CGTM are the operational centers responsible for the real-time monitoring and management of maritime traffic in Argentine waters.These centers act as Vessel Traffic Service (VTS) stations and coordinate, among other things:
- tracking of ships via radar, AIS, and other systems,
- providing information and advice to vessels,
- coordinating search and rescue operations (SAR),
- responding to emergency situations (such as breakdowns, flooding, or man-overboard incidents),
- enforcing maritime safety and preventing incidents in ports, rivers, and sea areas.
There are multiple CGTM centers spread across the country. But as far as I know only those in Mar del Plata, Buenos Aires, Comodoro Rivadavia and Ushuaia are active with a DSC watch on HF. With three of them confirmed Ushuaia is still on the to-do list.
