ARRL Technician Practice Exam

What must an amateur operator do when making on-air transmissions to test equipment or antennas?

1. Use a pseudonym

2. Properly identify the transmitting station

3. Inform others of the test plan

4. Coordinate with local authorities

The correct answer is: Properly identify the transmitting station

When making on-air transmissions for testing equipment or antennas, an amateur operator must properly identify their transmitting station. This requirement is critical because it maintains proper operating standards and compliance with regulatory rules established by the Federal Communications Commission (FCC). Proper identification ensures that other operators on the frequency are aware of who is transmitting, which helps to avoid confusion and coordinate communications effectively. Proper identification typically involves stating the call sign of the transmitting station at regular intervals, as dictated by FCC regulations. This practice promotes accountability and maintains an organized communication environment in amateur radio. It also assists in identifying potential interference and ensures that the airwaves are used responsibly. The other choices touch on aspects of communication but do not align as closely with regulatory requirements. For instance, using a pseudonym can lead to confusion, as it does not comply with identification rules. Informing others of the test plan and coordinating with local authorities are good practices for certain situations, but they are not mandatory for fulfilling identification requirements during equipment testing.
