Morse Tree

I made a Morse Codes Table and a Morse Tree which can be used for both International Morse and Japanese Morse.

Here your are !

As you see, Japanese Morse Code has almost double number of characters than for International Morse Code. Until 1996, we had to master both of them to get the 1st Class Amateur Radio Operator license.
In October, 2011, the Morse Code proficiency has completely deleted from the requirement of all sorts of amateur radio operators license.
