2. History of Morse code The invention of the Morse telegraphy system
Samuel F. B. Morse ( )
Professor of arts and design & Inventor of Morse Code
Assistant - Alfred Vail
Development of the code & Transmit instruments
From Washington to Baltimore - "What hath God wrought?"
Morse code originated on telegraph lines with clicking sounds

3. American Morse code as International Morse
Semi-automatic “bug” keys (1902)
Employment of electronic keyers that create “dits” & “dahs”
Today’s experienced operators
Copy text without writing & Transmit 20 ~ 30 words/minute

5. Introduction of Morse code
Long & Short pulses – representing the letters of the alphabet
Assign pattern to each character
Dits – short key closures Dahs – long key closures
Dash time = Dot time x 3
International Morse users created dahs with longer key closure
Pulses are translated into electrical signals by using a telegraph key
Transmission made possible for any distance
Radio communications – The widespread of international Morse

8. Some things to know about Morse code
