I thought Id mention that one of the things that was overlooked in the
Titantic disccusion is the CW was not invovled it was spark gap used in
that Morse encoded spark


Actually that is not correct.
Within the original meaning of CW, the Titanic used a CW transmitter.
It was not a spark transmitter, the rf energy was produced by an alternator
which provided 'continuous' rf power, hence CW. The output was not a damped
wave that a spark transmitter would produce, but an interrupted 'continuous
wave' (from the alternator).
