I am impressed not only at the use of Morse code but the fact it’s just broken enough to barely understand what he’s saying.
The morse code translates correctly for me so I think it's your tool that's broken. If you're using a phone it might be autocorrecting the dashes into larger dash symbols and messing it up. I'm impressed how many people actually translate the morse code! It makes me happy that people are interested enough in the game to do so.
