Deutsch: Funktionierender Funktelegraf in Form eines Löschfunkensenders zum Versenden von Morsezeichen im Elektromuseum in Frastanz
English: Working spark gap radiotelegraph transmitter for sending Morse code in the Electric Museum in Frastanz, Austria. Invented by Guglielmo Marconi in 1895, spark gap transmitters were used until about 1920. This low power induction coil transmitter worked off low voltage DC power, and may have been a shipboard transmitter. |
