🔍 Key Concepts

• FCC licensing structure for marine radio (difference between Marine Radio Operator Permit, GMDSS Radio Operator, and GMDSS Radio Maintainer) • Whether GMDSS Radio Maintainer is a standalone FCC license or an endorsement that sits on top of something else • The relationship between operator privileges and maintainer/technician privileges under GMDSS

💭 Think About

• Ask yourself: Does a person who only maintains GMDSS equipment necessarily need to be licensed to OPERATE all GMDSS functions, or can these be separate qualifications? • Think about how the FCC usually layers licenses: do higher or more technical licenses always require holding a more basic one first, or are some of them independent? • Look at the wording in each choice: which options are adding extra time or prerequisite licenses that may not be mentioned in FCC rules?

✅ Before You Answer

• Verify in FCC rules whether GMDSS Radio Maintainer is described as a separate license class or as an endorsement on an existing license • Check carefully if the rules ever mention a time-in-license requirement (like “held for at least one year”) for the GMDSS Maintainer • Confirm whether any rule explicitly states that a Marine Radio Operator Permit or GMDSS Radio Operator license must be held before or with the Maintainer qualification
