The GNS-480 decodes it for you and displays the letter

wrong but I would be able to correct it by listening myself.

Does it actually decode it or just display to info from its database.

It actually decodes it, and it has to decode it twice in a row the same way
before it display it. On a really weak signal, you can sometimes see it
get one of the letters wrong, then shortly after that, correct it.
