*Question T1E07:
[97.103(a)] When the control operator is not the station licensee, who is responsible for the proper operation of the station?*  

*Correct Answer is  D: The control operator and the station licensee*  

### AI Response: (may contain errors)  

When the control operator is not the station licensee, both the control operator and the station licensee are responsible for the proper operation of the station. This is outlined in the FCC regulations.

### Explanation of the Correct Answer:
- **Correct Answer: D (The control operator and the station licensee)**  
  - The FCC rules state that the control operator is responsible for the operation of the station while it is being used, but the station licensee retains ultimate responsibility for the station's compliance with regulations. Therefore, both parties share the responsibility.

### Why the Other Choices are Incorrect:
- **A: All licensed amateurs who are present at the operation**  
  - This choice is incorrect because not all licensed amateurs present are responsible. Only the control operator and the station licensee have defined responsibilities under FCC rules.

- **B: Only the station licensee**  
  - This choice is incorrect because it ignores the role of the control operator. While the licensee is responsible, the control operator also has a duty to ensure proper operation during their control.

- **C: Only the control operator**  
  - This choice is incorrect because it overlooks the station licensee's responsibility. The control operator is responsible for the operation, but the licensee is ultimately accountable for compliance with regulations.

### Summary:
- Both the control operator and the station licensee are responsible for the proper operation of the station when the control operator is not the licensee. This ensures accountability and compliance with FCC regulations.
