Which of the following is an acceptable method for identifying yourself during an amateur radio transmission?

• A. By your station's call sign only
• B. Using a pseudonym
• C. Broadcasting on any frequency
• D. Using your first name only

Answer: (A)

Identifying yourself during an amateur radio transmission is a fundamental requirement of the FCC rules. The correct method is to use your station's call sign. This call sign is a unique identifier assigned to your amateur radio station, and it serves several key purposes: it helps differentiate your transmissions from others, ensures the proper routing of communications, and fulfills legal obligations set by the FCC.

Using your call sign is also significant for maintaining clear and regulated communication within the amateur radio community, as it provides accountability and traceability for each operator. This method aligns with the rules set forth in Part 97 of the FCC regulations, which state that every amateur station must be identified by its assigned call sign at least every 10 minutes during a transmission and at the end of the communication.

In contrast to using a call sign, methods like a pseudonym or just your first name do not provide the necessary identification and could lead to confusion or non-compliance with the regulations. Broadcasting on any frequency is not a method of identification, as it disregards the importance of proper frequency usage as regulated by the FCC, and could potentially interfere with other communications. Thus, relying solely on your call sign is the only acceptable method that meets regulatory standards.
