Which data item includes the radio frequency and call sign?

• A. Date-Time Group
• B. Location coordinates
• C. Nationality and status
• D. Radio frequency and call sign

Answer: (D)

The data item that lists radio frequency and call sign is the one that explicitly includes both terms. Radio frequency identifies the specific channel being used, while the call sign uniquely identifies the transmitter. The other data items describe when something occurred (date-time), where it is (location coordinates), or who and their status (nationality and status), and they do not convey RF information. So the item that contains radio frequency and call sign is the correct choice.
