Which of the following statements about transmitting distress messages by radiotelephone is INCORRECT?
Official USCG Answer & Rule Citation
Correct Answer: Option C — It is advisable to follow a distress message on 2182 kHz by two dashes of 10 to 15 seconds duration.
Transmitting two long dashes of 10 to 15 seconds is an obsolete telegraphy practice used for direction finding, not radiotelephone procedures. Voice distress messages on 2182 kHz or Channel 16 require spoken MAYDAY protocols followed by identity and position.
