Happy to give European Community radio interference (8)
I believe the answer is:
ecstatic
'happy' is the definition.
(thesaurus)
'give european community radio interference' is the wordplay.
'give' is a charade indicator (letters next to each other).
'european community' becomes 'ec' (abbreviation).
'radio interference' becomes 'static' (radio static).
'ec'+'static' is 'ECSTATIC'.
'to' is the link.
(Other definitions for ecstatic that I've seen before include "Jubilant" , "Overjoyed, quite delighted" , "Extremely happy" , "Blissfully happy" , "Cites act about being thrilled to bits" .)
