Broadcast miracle save (7)
I believe the answer is:
reclaim
'save' is the definition.
(thesaurus)
'broadcast miracle' is the wordplay.
'broadcast' indicates anagramming the letters (letters scattered or cast around).
'miracle' anagrammed gives 'RECLAIM'.
(Other definitions for reclaim that I've seen before include "Miracle (anag)" , "Make (land) available for use" , "Get back (eg from the sea)" , "Convert" , "Get back (airline baggage)" .)
