Broadcast right artists on radio (10)
I believe the answer is:
transistor
'radio' is the definition.
(I've seen this before)
'broadcast right artists on' is the wordplay.
'broadcast' is an anagram indicator.
'right' becomes 'r' (common abbreviation).
'r'+'artists'+'on'='rartistson'
'rartistson' with letters rearranged gives 'TRANSISTOR'.
(Other definitions for transistor that I've seen before include "Electronic component" , "Electronic device" , "Semiconductor device" , "Radio" .)
