If the poster is scribbling down dahs and dits as he`s listening, he then has to look it up.
That is not how it is supposed to work. The official way is to write the navaid's ID when preparing the plog, including the dah-di-dits if needed, then confirm them in flight.
Morse code is no more an exam subject when going for the R/T license and there's a reason for that.
(yes, I did pass a separate R/T exam. EASA PPL'ers don't need to but a microlight pilot does, at least down here.)
