<Heinrich Hertz>'s main initial experiment used a <spark-gap transmitter>. It is not something that transmits recorded sounds like voice: it only transmits noisy beeps. And as such was used for <wireless telegraphy>.

{description=
Simplified recreation with cheap modern equipment. Uses as <transmitter> power source both:
* a <piezo igniter> from a <barbequeue lighter>
* a more powerful home-made <transformer>
and the signal is observed on the <receiver> with a <neon lamp>
