Final answer:
The station licensee must designate the station control operator.
Step-by-step explanation:
The station control operator is responsible for the operation and control of a radio station. This includes managing the station's equipment, ensuring compliance with regulations, and maintaining proper communication protocols. In the context of amateur radio, the station control operator is designated by the station licensee.
The station licensee is the individual who holds the license for the radio station, which grants them the authority to operate the station. They have the ultimate responsibility for the station and may designate the station control operator to assist in the day-to-day operations.
