Question
When may an amateur station transmit without identifying on the air?
Answer Options
- A) When the transmissions are of a brief nature to make station adjustments
- B) When the transmissions are unmodulated
- C) When the transmitted power level is below 1 watt
- D) When transmitting signals to control model craft
Correct Answer: D
Explanation
The FCC requires an amateur station to be identified at specific intervals during operation. However, there is a specific exception for control signals: an amateur station does not need to identify itself when the transmission is made solely for the purpose of transmitting signals to control model craft (like model airplanes, boats, or cars).
These control transmissions are often brief, rapid pulses that would be impractical to identify with a voice or CW call sign. This exception only applies to the actual command signals, not to other transmissions made by the control operator.
