🔍 Key Concepts

• Radiotelephone log requirements in 47 CFR Part 80 (ship stations) – what information must be recorded for safety and accountability • Why authorities need to reconstruct who said what, when, and to whom after an incident • Difference between a minimal log entry and a complete, compliant log entry

💭 Think About

• If there were an investigation after a collision, what specific information would investigators need from the radio log to understand the communications that took place? • Look at each option and ask: Does leaving this item out make it harder to identify the communication or the responsible operator? • Which choice best reflects the idea of a complete record of a transmission, rather than just a partial record?

✅ Before You Answer

• Verify that a proper radio log can identify time/date, which station you talked to, and who was operating the set. • Check whether regulations emphasize accountability of the operator as well as traceability of the communication between stations. • Before choosing, ask: Does any single item here logically exclude the others, or do they naturally build toward a more comprehensive requirement?
