The length of the burst of sparks could be lengthy or quick, relying upon how lengthy the transmitting key was depressed, and no sparks had been produced when the key was not pressed, and thus a Morse code message could possibly be despatched. The receiver used a coherer, which detected the sparks, linked to an aerial and the ground, and operated only when the transmitter was inactive. The receiver was linked to a printer that operated when a signal was found, and the messages had been then decoded by telegraphists.

However the physicist whose work should most of all be put in evidence is, without concern of contradiction, Heinrich Hertz It was he who demonstrated irrefutably, by experiments now classic, that an electrical discharge produces an undulatory disturbance within the ether contained within the insulating media in its neighbourhood; it was he who, as a profound theorist, a intelligent mathematician, and an experimenter of prodigious dexterity, made identified the mechanism of the manufacturing, and fully elucidated that of the propagation of those electromagnetic waves.
