Why this guide
- Built directly from the public FCC/USCG Element 7 question pool and 47 CFR § 13.203 — the same material used in approved GMDSS courses
- Equipment-by-equipment structure — VHF-DSC, MF/HF, Inmarsat, NAVTEX, and survival craft each get their own section because Element 7 tests each console separately
- Procedures you actually press — step-by-step distress alert sequences, DSC test calls, SafetyNET polling, and EPIRB/SART self-test routines
- FCC + STCW alignment — explains the difference between the FCC license (required to operate) and the USCG STCW endorsement (required to sail) so you know which certificate does what
- Print-friendly — full guide for classroom study, two cheat sheets for quick console review, pocket crib sheet for the bridge
Who this is for
- Deck officers seeking the FCC GMDSS Radio Operator’s License (GOC) for STCW ships
- Mariners who operate VHF-DSC, MF/HF, Inmarsat, NAVTEX, and EPIRB/SART equipment
- GMDSS course graduates preparing for the FCC Element 7 examination
- Shipboard electronics technicians upgrading to the GMDSS Maintainer endorsement
- Offshore, ferry, cargo, and cruise crew who need Sea Area A1–A4 communications competence
What you'll learn
- General Information and System Overview: GMDSS concepts, equipment systems, Sea Areas A1–A4, functional/carriage requirements, and maintenance options
- Digital Selective Calling (DSC): call signs, SELCALs, MMSI/MID, Inmarsat mobile numbers, DSC format, information sent, DSC operations, and DSC frequencies
- Distress, Urgency, and Safety Communications: sending distress alerts, follow-on voice transmissions, response to distress alerts, distress relays, false alerts, radio silence, urgency/safety traffic, and frequencies
- Survival Craft Equipment and SAR: SART activation/testing, EPIRB operation, homing/locating signals, survival-craft transceivers, on-scene communications, and SAR/MCC/RCC procedures
- VHF-DSC and Maritime Safety Information: VHF controls, channel system, USA-INT/simplex/duplex operations, NAVTEX operation/programming/message format, SafetyNET, EGC, HF MSI, and NAVAREAs
- Inmarsat and MF-HF Equipment: Inmarsat B/C/F77/Sat-C controls, ocean-region selection, log-in/log-out, LES selection, addressing/dialing, transceiver controls, SITOR/NBDP ARQ and FEC modes, propagation, and battery testing
- Regulatory framework: 47 CFR Part 13 (Elements 1 and 7), 47 CFR Part 80 Subpart W, § 80.1069 Sea Area definitions, § 80.1081 operator functions, SOLAS Chapter IV, and the USCG/FCC joint Element 7 question pool
