Desire broadcast to be live (6)
I believe the answer is:
reside
'be live' is the definition.
(I've seen this before)
'desire broadcast' is the wordplay.
'broadcast' is an anagram indicator.
'desire' anagrammed gives 'RESIDE'.
'to' acts as a link.
(Other definitions for reside that I've seen before include "Live (at an address)" , "Lodge" , "Dwell permanently" , "Make one's home permanently" , "Dwell - settle" .)
