Question 262 Deck Safety

The correct answer is D) Always at the beginning and ending of a transmission. According to the U.S. Coast Guard regulations, mariners are required to use their FCC-assigned call sign when transmitting on channel 16, which is the international distress, safety, and calling frequency. This call sign must be used at the beginning and end of each transmission, as it helps to identify the source of the communication and assists the Coast Guard in responding appropriately. The other options are incorrect because: A) The call sign is required at both the start and end of the transmission, not just the beginning. B) The call sign must be used regardless of whether the Coast Guard requests it. C) The call sign is required for all transmissions on channel 16, not just in emergencies.
