Radio broadcast by English band crew member (6)
I believe the answer is:
roadie
'band crew member' is the definition.
(I've seen this before)
'radio broadcast by english' is the wordplay.
'broadcast' indicates an anagram.
'by' says to put letters next to each other.
'english' becomes 'e' (abbreviation).
'radio' anagrammed gives 'roadi'.
'roadi'+'e'='ROADIE'
(Other definitions for roadie that I've seen before include "One handles equipment for travelling entertainers" , "Musical tour crew member" , "Touring band's supporter" , "Band crew member" , "Touring band's helper" .)
