I believe the answer is:

proclaimed

I'm a little stuck... Click here to teach me more about this clue!

'broadcast' is the definition.
(thesaurus)

'classic about transport of coal by germany' is the wordplay.
'classic' becomes 'prime' (I can't explain this - if you can you should give a lot more credence to this answer).
'about' indicates putting letters inside.
'transport of' indicates an anagram (I've seen 'transported' mean this).
'by' says to put letters next to each other.
'germany' becomes 'd' (international vehicle registration code).
'coal' anagrammed gives 'ocla'.
'prime' enclosing 'ocla' is 'proclaime'.
'proclaime'+'d'='PROCLAIMED'

Can you help me to learn more?

(Another definition for proclaimed that I've seen is " Lauded".)

I've seen this clue in The Telegraph.
