Which of the following are required for remote control operation?
The correct answer is D: All these choices are correct. According to FCC Part 97.3(a)(38), remote control requires all three elements: (1) the control operator must be at the control point (where control is exercised), (2) a control operator is required at all times, and (3) the control operator must indirectly manipulate the controls (not directly at the equipment location).
Remote control allows operation when the control operator is not at the same location as the transmitting equipment, but the operator must still be actively controlling the station from the control point. The operator uses indirect means (like internet, radio link, or other methods) to control the station. All three requirements must be met for proper remote control operation.
Exam Tip
Remote control = All three requirements. Remember: Remote control requires the operator to be at the control point, an operator required at all times, and indirect manipulation of controls. All three are necessary.

Real-World Application
You have a remote station on a mountaintop, and you control it from your home office over the internet. You're at the control point (your home), you're actively controlling the station (operator required), and you're using indirect means (internet) to manipulate the controls. This meets all three requirements for remote control operation.

Why Other Options Are Wrong
This question has no incorrect options since all choices are correct. However, it's important to understand that all three elements are required for remote control: operator at control point, operator required at all times, and indirect manipulation of controls.
