Broadcast condensed, not on in fall (7)
I believe the answer is:
descend
'fall' is the definition.
('descend' can be a synonym of 'fall')
'broadcast condensed not on' is the wordplay.
'broadcast' is an anagram indicator.
'not' is a deletion indicator.
'condensed' with 'on' taken away is 'cdensed'.
'cdensed' is an anagram of 'DESCEND'.
'in' acts as a link.
(Other definitions for descend that I've seen before include "Climb down" , "Go down" , "Alight" , "Move downwards" , "Plunge" .)
