He raises game in early edition of programme on radio (6)
I believe the answer is:
beater
'he raises game' is the definition.
(person who raises game birds for shooting)
'early edition of programme on radio' is the wordplay.
'early edition of programme' becomes 'beta' (as in a beta version of software).
'on radio' shows a homophone (sound like).
'beta' sounds like 'BEATER'.
'in' acts as a link.
(Other definitions for beater that I've seen before include "guy rousing game" , "Person employed to rouse game" , "One raising game birds" , "One disturbs game" , "One who makes birds fly for a shoot" .)
