Fail to broadcast (4,3)
I believe the answer is:
give out
I believe this is a double definition.
'fail' is the first definition.
('give out' can be a synonym of 'fail')
'broadcast' is the second definition.
(I've seen this before)
'to' is the link.
(Other definitions for give out that I've seen before include "Announce or emit" , "Broadcast" , "Distribute or complain slangily (4.3)" , "stop functioning" , "Distribute or complain informally" .)
