Offensive outside broadcast location (7)
I believe the answer is:
obscene
'offensive' is the definition.
(similar in meaning)
'outside broadcast location' is the wordplay.
'outside broadcast' becomes 'ob'.
'location' becomes 'scene' (scene is a kind of location).
'ob'+'scene'='OBSCENE'
(Other definitions for obscene that I've seen before include "Offensively vulgar" , "blue" , "Indecent or pornographic" , "repellent" , "Offensive - indecent" .)
