Liner sets out to get radio audience (9)
I believe the answer is:
listeners
'radio audience' is the definition.
(I've seen this in another clue)
'liner sets out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'liner'+'sets'='linersets'
'linersets' is an anagram of 'LISTENERS'.
'to get' acts as a link.
(Other definitions for listeners that I've seen before include "Those who pay attention" , "They follow advice" , "The audience" , "Radio fans" , "Hearers" .)
