" That's why there was an international agreed to distress call, although
at the time, radio operators were NOT obligated to listen or act upon it.
"CQD" was not a distress call per se, it was Marconi company code for
"assistance" as in "CQD CQD CQD" meaning send assistance and "CQD?"
meaning
"do you need assistance".

Telefunken operators were not privy to Marconi company internal codes,
and were forbidden by company policy (and Marconi's) to answer them.
Of course nothing is secret for long and it is quite likely that most
Telefunken operators heard the CQD call from the Titanic, understood it
and listened, although none of them were going to do anything about it.

When the Titanic operator sent the new distress call (which I can't write
due to text limitations) of ...---... as one continuous string (not the
letter
S followed by the letter O followed by the letter S), anyone listening
knew what they were sending. The confusion to the reader of this is
because
it is written as SOS with a line on top of all three, so if I could do it,

If you look at the radio logs you will find that Titanic only used SOS once
at 12:45am, and that was to MKC - her sister ship, the Olympic. The callsign
MKC indicating that she was also a 'Marconi' ship. The rest of the time CQD
was used.

Also to explode your theory even more at 12:15am Frankfurt DFT replied to
Titanic's CQD;
12:26 DKF (Prinz Friedrich Wilhelm) called the Titanic;
1am DDC (Cincinatti) replied to Titanic's CQD.
etc.etc

None of these were Marconi ships!!

and finally the Californian (MWL) was also a Marconi ship!!! So no
Telefunken operator to ignore any CQD's.
