The International Morse Code(CW)
Introduction.
At the time I applied for my 5Z4FT license about late 1980's, while still in high school, proficiency in The International
Morse code was a requirement. I learnt CW only to satisfy licensing requirements at the time, and
forgot about it as soon as I made my first SSB QSOs. As a necessity, I have had to polish-up my
International Morse Code skills, and having enjoyed myself in the process, thought-up this page to
help those operators who may wish to improve their CW skills, or for those who want to learn a new
skill.
The International Morse code is a mode developed by Samuel Morse among others, to transmit
information using on, and off keying of a signal or light source, a combination of these on, and
off elements being used to build single characters into words. It was the first digital
communication mode, and still remians as such. For illustrative purposes ,the dot element may be
considered a single bit element, or logic one, the dash a series of single bit elements, or logic
ones, following each other consecutively, while the space/time element, the absence of a tone bit
or logic zero(Using Positive Logic). It remains the easiest mode to use over long distances, with
simple equipment on low power, under difficult conditions. When compared to other digital modes has
the lowest baud rate, which gives the apparent sense of obsolescence in todays high speed data
world. For many people who may be disabled, or lack cross language skills, the simple Morse Code
English language abbreviated shorthand allows operators to communicate effectively. Apart from the
obvious Mathematical sense, the Morse Code has a Musical sense to it, and is fun to use.
