Spark-gap transmitters running 5,000 watts make me feel all tingly inside!
Nowadays, I suspect an FT-817 running 5 watts and a Buddipole clamped to a railing could accomplish the same thing those big Marconi rigs and hundreds of feet of wire antenna did, and so much more.
After a series of maritime accidents in the early 20th century, the need to standardize procedures and systems for wireless maritime distress became increasingly apparent. The Titanic’s sinking accelerated a process that to this day continues to improve communications technology at sea.
