Broadcast exposed anger (3)
I believe the answer is:
ire
'anger' is the definition.
(ire is intense rage)
'broadcast exposed' is the wordplay.
'broadcast' becomes 'aired' (synonyms).
'exposed' says to take the centre (the inside of the word is exposed).
The centre of 'aired' is 'IRE'.
(Other definitions for ire that I've seen before include "Anger among admirers" , "Fury" , "Strong feeling" , "Hot temper" , "'Anger, wrath (3)'" .)
