🔍 Key Concepts

• FCC commercial operator licenses and how upgrades are handled • Whether multiple radiotelegraph operator licenses of different grades can be valid at the same time • What it means, administratively, to modify, cancel, or let a license expire

💭 Think About

• If a mariner already holds a lower-grade radiotelegraph license and later qualifies for a higher grade, what is the most logical way for the FCC to keep the records simple and clear? • Look carefully at which options would create confusion in determining what privileges the operator actually has at sea. • Think about the difference between a license automatically changing status versus just having more than one active at once.

✅ Before You Answer

• Check which options imply holding more than one unexpired radiotelegraph license at the same time. • Note the difference between a license being modified/updated versus being canceled or just allowed to expire. • Ask yourself: for enforcement and inspection, would the FCC more likely want one current certificate that reflects your highest qualification, or several overlapping ones?
