When must an amateur station have a control operator?

An amateur station must have a control operator whenever the station is transmitting. This is because the control operator is responsible for ensuring that the station operates in accordance with the rules and regulations set forth by the Federal Communications Commission (FCC). The control operator must be present to manage the transmission, ensure compliance with operating privileges, and handle any issues that may arise during the operation of the station.

The presence of a control operator is particularly important during transmissions to ensure that all communications are conducted legally and within the amateur radio service guidelines. This includes observing bandwidth limits, following proper operating protocols, and avoiding interference with other broadcasts. Even if the radio is being operated via automated systems or remote control, a control operator must oversee the operation if the station is actively transmitting signals.

In scenarios where the station is not transmitting, it may not require a control operator, reflecting the fundamental requirement that the control operator's responsibility arises specifically during transmission activities. This requirement helps maintain the integrity of amateur radio communications and the responsible operation of the equipment.
