Liners set out for radio audience (9)
I believe the answer is:
listeners
'radio audience' is the definition.
(I've seen this in another clue)
'liners set out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'liners'+'set'='linersset'
'linersset' with letters rearranged gives 'LISTENERS'.
'for' is the link.
(Other definitions for listeners that I've seen before include "Hearers" , "Performers of tap" , "radio enthusiasts" , "The audience" , "Radio fans" .)
