Stirs up old views on the radio (7)
I believe the answer is:
excites
'stirs up' is the definition.
'excites' can be an answer for 'stirs' (exciting is a kind of stirring). I'm not certain of the 'up' bit.
'old views on the radio' is the wordplay.
'old' becomes 'ex' (prefix meaning former or onetime).
'views on the radio' becomes 'cites' (I am not sure about this - if you are sure you should believe this answer much more).
'ex'+'cites'='EXCITES'
Can you help me to learn more?
(Other definitions for excites that I've seen before include "Thrills" , "Kindles" , "Stirs up, rouses" , "Animates" , "Provokes" .)
