When may an amateur station transmit without a control operator?

• A. During automated operations
• B. When using digital modes only
• C. Never
• D. When the station is unattended

Answer: (C)

An amateur station is always required to have a control operator present when it transmits. This requirement ensures that there is someone responsible for proper operation and compliance with FCC regulations. The control operator must be able to oversee the transmission to address any potential violations or issues as they arise.

While there are specific scenarios, such as automated operations or unattended stations, that might seem to imply that a control operator isn't necessary, regulations state that there must always be a qualified operator overseeing transmissions. This ensures accountability and adherence to radio operating standards regardless of the mode of transmission or operational circumstances.

Therefore, the necessity for a control operator emphasizes the importance of responsible communication practices within the amateur radio community.
