Which of the following are required for remote control operation?

Remote control operation is defined by the FCC as the operation of a station where the control operator is not physically located at the station transmitter. Because a human must still be in charge to ensure regulatory compliance, a control operator is absolutely required at all times during operation. Furthermore, this control operator must be present at the designated 'control point' (where the control interface is located) and must indirectly manipulate the station's controls, often over a network or a separate radio link. Since all three of these individual statements are true requirements for remote control, the correct answer is that all of these choices are correct.
