Question 6A564

The correct procedure for making a distress call, as outlined in international radio regulations adopted by the FCC, prioritizes clarity and redundancy. The distress signal itself (MAYDAY for voice, SOS for Morse code) is transmitted three times to ensure it is clearly recognized as a genuine emergency. This is immediately followed by the word "DE" (meaning "from"), and then the callsign of the station in distress, also transmitted three times. This repetition significantly increases the chance of successful reception and identification, especially under difficult communication conditions. Option A is too vague, as merely stating the call is made "three times" doesn't specify the precise structure. Option B is incorrect because the distress signal (SOS for CW) is repeated three times, not twice, and "MAYDAY" is used for voice. Therefore, C accurately describes the standard, universally recognized distress call format.
