Move out of sight on the radio! (6)
I believe the answer is:
excite
'move' is the definition.
(thesaurus)
'out of sight on the radio' is the wordplay.
'out of' becomes 'ex'.
'on the radio' shows a homophone (sound like).
'sight' is a homophone of 'cite'.
'ex'+'cite'='EXCITE'
(Other definitions for excite that I've seen before include "Cause strong feelings in" , "Act as a stimulant" , "Arouse, make eager" , "fire" , "Create enthusiasm" .)
