Summary: Although Morse code is no longer required to get a ham license, it's still quite popular, and can be a draw for some potential hams before they get licensed. Learning it is one thing, but being able to use it while still learning is a challenge before you're licensed and have a station set up. Scotty Cowling WA2DFI used his TAPR skills to develop an improved, inexpensive and easy-to-build CPO (Code Practice Oscillator). That led to an online system that also needed some improvement.
