J38 Telegraph Key
J38 Telegraph KEY
wikipedia
https://en.wikipedia.org/wiki/Morse_code

The Canadian Encyclopedia;
The technology was conceived in North America by Samuel Morse in 1837,
The first telegraph message transmitted in Canada was sent from Toronto to Hamilton on December 19, 1846,

Beginning in 1836, the American artist Samuel F. B. Morse, the American physicist Joseph Henry, and Alfred Vail developed an electrical telegraph system.
This system sent pulses of electric current along wires which controlled an electromagnet that was located at the receiving end of the telegraph system.

Development and history;
Typical "straight key". This U.S. model J-38, was manufactured in huge quantities during World War II.
The signal is "on" when the knob is pressed, and "off" when it is released.
Length and timing of the dots and dashes are entirely controlled by the telegraphist.

LEARNING MORSE CODE
Excerpt;
Morse Code Speed
To understand code speed, it is helpful to look at the method in which code is generated. Code di's (dots) and dah's (dashes) and the spaces between them are sent using standard fixed time intervals.
http://www.mechanicalpuzzles.org/codepractice/learning.html

Spacing between letters within a word is three time units long, or in our slow code example, will take three seconds.
Spacing between words will be seven time units.
http://www.morsecodeclassnet.com/lesson3

One unit = 1 pixel = 1 second
graph = 51 pixels
space between words = 7 pixels
51 pixels

The length of a dot is one unit.
A dash is three units.
The space between parts of the same letter is one unit.
The Space between letters is three units.
The space between words is seven units.
Generally 1 pixel is one second and the space between words is 7 pixels.
BEEPS(sound) = Continuous Wave = CW.

calling for help When in extreme danger (for example, your boat is taking on water and you are in danger of sinking or capsizing), use your VhF radio channel 16 and say “Mayday”— “Mayday”—“Mayday.”
Then give the name of your boat, its position, the nature of your problem and the type of help you need.
if you need help but are not in immediate danger (for example, your motor has quit and you cannot reach shore), use channel 16 and say “Pan Pan”—“Pan Pan”—“Pan Pan.

Morse Code Timing
A standard for morse timing using the Farnsworth technique
In recent years there has been a renewed interest in Farnsworth timing of morse transmissions. Farnsworth timing is defined as sending the characters at a faster speed than the words. for example, sending the characters at 20 WPM but adding enough time between them to slow down the rate to 10 WPM...
