'programme' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps there's an association between them I don't understand?

'raid organised by old extensive actors' is the wordplay.
'organised' indicates anagramming the letters.
'by' is a charade indicator (letters next to each other).
'old' becomes 'o' (abbreviation).
'extensive' becomes 'broad' (similar in meaning).
'actors' becomes 'cast' (group of actors).
'raid' anagrammed gives 'radi'.
'radi'+'o'+'broad'+'cast'='RADIO BROADCAST'

'making' is the link.

Can you help me to learn more?

(Another definition for radio broadcast that I've seen is " transmission".)
