Broadcasting it may produce friendship (5)
I believe the answer is:
amity
'friendship' is the definition.
(I've seen this in other clues)
'broadcasting it may' is the wordplay.
'broadcasting' indicates anagramming the letters.
'it'+'may'='itmay'
'itmay' anagrammed gives 'AMITY'.
'produce' acts as a link.
(Other definitions for amity that I've seen before include "Cordiality" , "warmth" , "Friendly relations" , "Friendship - goodwill" , "Cordial friendship" .)
