Knowledge base
Tests show what you know. The articles explain why.
Eighteen articles written for the SRC exam rather than adapted from a textbook, split into four parts.
Alerting
MAYDAY, MAYDAY RELAY and radio silence, PAN PAN, SECURITE, and how to cancel a false alert.
Equipment
The VHF radio with DSC, the EPIRB beacon, the SART transponder, NAVTEX, and the path your alert takes through COSPAS-SARSAT, with photos of the hardware.
Communication
The phonetic alphabet, VHF channels, calling a ship or a coast station, and reading out numbers, positions and time.
Basics and regulations
How the exam runs, GMDSS and sea areas A1 to A4, MMSI and ship documents, priority of communication and the duties of a radio operator.
Every article carries an estimated reading time and ends with related topics. Search ignores Polish diacritics, so typing lacznosc finds Łączność.
