Money raised during radio broadcast (5)
I believe the answer is:
bread
'money' is the definition.
(bread is slang for money)
'raised during radio broadcast' is the wordplay.
'raised' becomes 'bred' (eg bred children).
'during radio broadcast' indicates a 'sounds like' (homophone) clue (how it might sound on the radio).
'bred' is a homophone of 'BREAD'.
(Other definitions for bread that I've seen before include "Bloomers, say" , "brass" , "Nan, for instance" , "Lolly - basic food" , "Food made from dough" .)
