Who is eligible to be the control operator of an amateur station?

The correct answer indicates that a control operator for an amateur station must either have an amateur operator or primary station license grant that is recorded in the Federal Communications Commission (FCC) database or be authorized for alien reciprocal operation.

This requirement ensures that only individuals with verified licenses, which demonstrate their knowledge of regulations and operational skills, are responsible for the operation of amateur radio stations. The FCC maintains a database that lists licensed operators, providing a clear and accessible way to confirm that someone is legally allowed to operate amateur radio equipment.

Moreover, the recognition of alien reciprocal operation allows licensed operators from other countries to be control operators under specific agreements, promoting international cooperation in amateur radio. This reflects the global nature of the hobby and adherence to international regulations concerning radio spectrum use.

The other answer choices describe various limitations that are not aligned with the actual FCC requirements. For instance, a person does not need to be a U.S. citizen or over the age of 18 to be a control operator; younger operators can hold licenses at any age, and international operators can engage in amateur radio activities as long as they meet the authorization criteria. These elements highlight the inclusive nature of amateur radio while maintaining the necessary regulations to ensure responsible operation.
