While some software only deciphers Morse code, training software is also available so you can learn to decipher Morse code yourself.
Just Learn Morse Code
Just Learn Morse Code is simple, free Morse code software that uses the Koch's method to teach Morse code. The Koch's method starts by training you in two letters of Morse code in five minute intervals. When you have mastered those letters as demonstrated by a 90% accuracy rating tracked by the Morse Code training software, additional letters are added. Ideally, you will progress at the correct rating, learning more and more Morse code as you progress through the Just Learn Morse Code program.
The Just Learn Morse Code software allows you to record your sessions into audio files, which can be replayed at a later date. Use the practice software to learn Morse code, or type in your message and save it as a recording to be transmitted at a later date. Just Learn Morse Code is free to download and use, but there is a donate button to contribute to the software author for his work and for future development of the program. However, donations are not required to use the software.
