Radio telephone stations required to keep logs of their transmissions must include?

• A. Date and Time of Transmissions
• B. Call Signs Involved
• C. Message Content
• D. All of These

Answer: (D)

Keeping a complete record of radiotelephone transmissions is required to provide an auditable trail for safety and regulatory oversight. Each log entry should include the date and time of the transmission to establish when it happened; the call signs involved to identify the communicating stations; and the content of the message so the exact information conveyed is preserved. Without any of these elements, the log would be incomplete: missing time obscures sequencing, missing call signs hides who talked, and missing content leaves what was said unknown. Therefore, a proper log must capture all three aspects.
