🔍 Key Concepts

• FCC commercial radiotelegraph operator license structure (Second Class vs First Class) • Regulatory focus on prior licensing vs general experience • Difference between employment time on a ship and holding a certificate

💭 Think About

• Which options describe specific license-holding time and which describe more general or vague experience? • For upgrading in many license systems, do regulations usually require time actually holding the lower license, or just any kind of related background? • Does the question ask about general radio experience or the formal requirement tied to the First Class Radiotelegraph license?

✅ Before You Answer

• Identify which choice mentions having held a Second Class Radiotelegraph Operator’s Certificate for a minimum time • Check which options talk about employment as radio operator on a U.S. ship rather than license-holding time • Decide whether the official requirement is based on formal license history or broad message-handling experience
