Agree that! Forget the little charts, and learn the music of the morse. I learned it back in the dark ages for my amateur radio licence, and it's been a great help when flying.
Yes, the examiner will "comment" if you don't look at the printed dots and dashes, but explaining that you read morse will avoid any problem. It's great when you mistune a VOR or press a wrong button, and recognise the different (unexpected) ident.
The FAA certainly wanted me to ident any navaid on my IR checkride - and to leave the ADF ident running the whole time I was using it, in case it went "off air" during the procedure or missed.
