Frank rigs that broadcast (8)
I believe the answer is:
straight
'frank' is the definition.
(I've seen this before)
'rigs that broadcast' is the wordplay.
'broadcast' is an anagram indicator (letters scattered or cast around).
'rigs'+'that'='rigsthat'
'rigsthat' with letters rearranged gives 'STRAIGHT'.
(Other definitions for straight that I've seen before include "Honest - direct" , "Direct, having no deviations" , "Serious" , "Linear" , "Undeviating" .)
