Question
What is the maximum permissible duration of a remotely controlled station’s transmissions if its control link malfunctions?
Answer Options
- A) 30 seconds
- B) 3 minutes
- C) 5 minutes
- D) 10 minutes
Correct Answer: B
Explanation
Remote control allows an amateur station to be operated from a location other than the station location. This type of operation requires safeguards to prevent unauthorized or runaway transmissions in the event of a control link failure. The FCC specifies rules for what must happen if the circuit that provides the control link fails.
If the control link for a remotely controlled station malfunctions, the rules require that the station’s transmissions must cease completely within 3 minutes. This time limit is designed to prevent prolonged, unmonitored operation that could cause unnecessary interference or violate other regulations. It necessitates a fail-safe mechanism in the remote control design.
