Marconi’s Atlantic leap and Telegraph exhibit

Telegraph Key

     In the Marconi Hotel is the Quarter Century Wireless Association (QCWA) Telegraph and Marconi’s Atlantic leap exhibit.  This hands-on educational exhibit is enjoyed by all.  There is something magic about sending coded messages.  The exhibit features a room length model of a basic telegraph system and a wall size graphic of Marconi’s 1901 wireless ‘leap’ across the Atlantic Ocean.  

     The telegraph exhibit has a key at each end of the rail line for Morse code practice between rail stations.  A fun effect is each miniature telephone pole has a LED light on top showing the transmission of the signal from station to station.  Some how the signal transmission speed is far slower than the speed of light.   For those who have never hear a sentence in Morse code, a touch of a button will reproduce the first Morse code message sent between Baltimore, Md. and Washington D.C. in 1843.

 In 1901 Marconi achieved the impossible.  His experimental wireless system sent a wireless signal across the Atlantic Ocean.  Known as the ‘Atlantic leap’ it was breakthrough in world wide wireless.  The wall size exhibit is complete with a piece of the ionosphere on the ceiling for the signal to reflect back to earth.
