At the time there was no clear procedures for wireless communications. The Marconi Boys on the Titanic spent their time sending telegrams for the 1st Class passengers, telegrams that were on the order of “Isn’t this great I am still in the middle of the Atlantic” messages. There was no mandatory radio watch standing by shore installations, and ships at sea that were equipped with Marconi’s were in the same position. When passing ships tried to warn the Titanic about icebergs the Marconi’s were too busy sending those “isn’t this the coolest thing” telegrams. The Marconi transmitter on the Titanic was not particularly powerful either. Naval vessels of the time had high powered rotary transmitter of many KW’s.
Being a hamradio operator this aspect of the Titanic shipwreck is of great interest. It was a hamradio operator on shore that first reported the disaster, and at first he was not believed.
Here is a recreation of the Marconi room on the Titanic.
