When logging communications in the field, what information is essential to record?

• A. Personal opinions about the caller
• B. Only the length of the call
• C. Date and time, call sign, summary of content, actions taken
• D. Irrelevant details

Answer: (C)

In field communications, the log must capture information that lets you reconstruct what happened, who was involved, and what needs to be done next. The essential record includes the date and time of the contact, the call sign of the transmitter or station, a concise summary of what was discussed or requested, and any actions taken or required. This combination provides a clear, verifiable trail for accountability, after-action review, and follow-up.

Personal opinions about the caller should not appear in the log, as they’re subjective and not verifiable. Recording only the length of the call fails to convey what was communicated or decided, and including irrelevant details clutters the record and can hide the important points.
