Morse code is a communication method - perhaps an art - that goes back to the mid 19th century. It is one of the very first ways that humans devised to encode natural language as electrical pulses. Once radio was introduced to the world, Morse code was quickly adapted to enable wireless long distance communication, long before voice transmission was possible.

In an age where worldwide communication at multi-Gigabit speeds is ubiquitous, it might seem counterintuitive that Morse code is still used by amateur radio operators and hobbyists all over the world. And thus the art of Morse code continues to fascinate and interest old-timers and newcomers alike.

The so-called Continuous Wave (CW) modulation occupies a significant portion of the ham radio bands.

Learning Morse code is nothing short of learning a new language. Fluent understanding of Morse code involves training the brain to recognize the audible sounds of each character and immediately understand them as the representation of a letter, digit or a procedural sign (prosign). More advanced learning of the code expands this skill to recognize the sound of complete words.

Just like human language is learned through practice and repetition that tells us that the consonant "see" is the audible representation of the letter "C", we can learn that the sound of

represents the same letter.

Master CW allows anyone interested in learning or improving their Morse code skills to do so as quickly and efficiently as possible. The intelligent lesson engine behind Master CW focuses the user on the characters that require the most practice when it comes to speed and accuracy.

The visual cues in each lesson help ingrain the audible and visible patterns not only in memory but in deep cognitive recognition.

Master CW was built to facilitate modern, web-based learning of Morse code, in a fun and efficient way. Go ahead and try it out, we hope you find it useful just as much as we do!
