Description
English: Part of a Morse code message received and recorded by a telegraph siphon recorder. This was recorded after passing though an Eastern Telegraph Co. underwater telegraph cable about 830 miles long, with earth return circuit. The almost indecipherable message illustrates the great distortion of signals in early transatlantic telegraph cables.
