Hi I'm a bit confused with pandanticity of the CW ident. the classification of the speed of sending morse is weird anyway. definition of a word ???? definition of a character ???? Why not just take the longest word in the dictionary , multiply that by 20, and count up all the letters, I guess someone will want to take the mean average of between an E and probably a J so with that you can wind the wick up until you you can send all the characters in your callsign in a couple of seconds. If its going to be read by any gov agency it will be machine read anyway antidisestablishmentarianism , that was the longest when I was at school 73
