AE Morse HD Plus a Droid application that teaches you Morse code (CW). It has an interactive screen for learning the alphabet plus much more. The best way to learn Morse code is by ear. AE Morse plays actual Morse code sound instead of just blinking or vibrating your Droid.In addition to training screens, there is a screen that allows you to play Morse code (CW) practice files directly from the AE web site. Files display the text and play the audio at a speed of 5 to 30 words per minute. Files are updated regularly, so you will consistently get new files to practice.Please send any suggestions for improvement, or requests to jadkins@jadkinsenterprises.com so we will know how we are doing.CW can successfully be received under some conditions where voice can not. You can tune out more of the interference on a received CW message using a decent ham radio. Having the skill of CW can be an asset during emergency situations where other forms of communication may not be possible.
