What symbol must be included in the preamble of every distress-traffic radiotelegram after a distress call?

• A. SOS followed by the call signal
• B. The distress signal preceding the call and repeated at the beginning of the preamble
• C. All of the above
• D. None of the above

Answer: (B)

In distress-traffic radiotelegrams, it is crucial to maintain a clear and recognized communication protocol to ensure that all emergency messages are properly identified and prioritized. The correct answer involves the inclusion of a distress signal preceding the call along with its repetition at the beginning of the preamble. The distress signal, typically represented as SOS, serves as an internationally recognized indicator that immediate assistance is required. By including this distress signal in the preamble of the radiotelegram, it reinforces the urgency of the message. The repetition of the distress signal helps ensure that there is no ambiguity about the nature of the communication, thereby facilitating swift and appropriate action from those receiving the message. Using only the call signal or merely indicating distress without clear reiteration would not be sufficient to alert operators to the critical nature of the situation. Thus, including the distress signal at the beginning of the preamble is a required practice in accordance with maritime communication protocols.
