For a period of ca. seventy years telecommunication was only possible by way of transmission methods using the Morse code. The Morse alphabet, in the form still officially and globally widespread to this day, was invented a good 150 years ago by the German Clemens Gerke. This art of broadcasting messages by way of Morse telegraphy was and still is only possible if one has specialist knowledge and skills. It is a type of intercultural form of culture and communication that overcomes the barriers of time and space ( Morse Code as UNESCO Intangible Cultural Heritage). The transmission of messages by way of the Morse code is nowadays no longer necessary for technological, economic and military reasons. Morse code is fun to learn (lcwo, N0HFF) and due to its simplicity wide range of experiments with communication technologies can done with little cost.
