RMS Titanic "SOS"

 

The final radiotelegraph transmissions from the Titanic. This recording is in all likelihood a simulation, but its exact origin is not known. It is notable for the authentic-sounding rotary spark gap tone and also for the code speed-- rather quick for a hand key! A video of the keying waveform is provided for further analysis.
