Remember there may be people who can hear you and can not hear the distress station. If it is an SOS the response is basically the same. The receipt response is “r SOS AR.” Stay on frequency and listen as long as you can or until the distress is over.
In modern terminology, SOS is a "procedural signal" or "prosign", and the formal way to write it is with a bar above the letters. It should be written SOS. In popular usage, SOS became associated with phrases such as "Save Our Souls," "Save our Ship", and others.
In the language of Morse code, the letter “S” is three short dots and the letter “O” is three longer dashes. Put them together and you have S.O.S. These sounds represent the international call for help because they are easy to recognize. Now, it is simply known as S.O.S.
But before “SOS” was the international distress symbol, “CQD” did the job. The signal “CQD” was derived from an earlier code, “CQ,” commonly used by telegraphers and wireless operators to address all stations at once.
Although SOS officially is just a distinctive Morse code sequence that is not an abbreviation for anything, in popular usage it is associated with phrases such as "Save Our Souls" and "Save Our Ship".

The Mayday call originated in the 1920s. As much of the traffic at Croydon airport at that time was to and from Le Bourget Airport in Paris, Mockford proposed the expression “Mayday" derived from the French word “m'aider" that means “help me" and is a shortened form of “venez m'aider", which means “come and help me".
The "mayday" procedure word was conceived as a distress call in the early 1920s by Frederick Stanley Mockford, a senior radio officer at Croydon Airport, London. He had been asked to think of a word that would indicate distress and would easily be understood by all pilots and ground staff in an emergency.
A Mayday call is a distress signal used during emergency procedures. It indicates life-threatening emergency especially by aviators and mariners. However, fire-fighters and police forces also use them. How is a Mayday call used? In times of emergency, the call is issued three times in a row - 'Mayday Mayday Mayday'.
