Island ways broadcast (6)
I believe the answer is:
rhodes
'island' is the definition.
(Greek island)
'ways broadcast' is the wordplay.
'ways' becomes 'roads' (road is a kind of way).
'broadcast' indicates a 'sounds like' (homophone) clue (how the word might sound on the radio or TV).
'roads' sounds like 'RHODES'.
(Other definitions for rhodes that I've seen before include "She and Rod have a Greek holiday here" , "Largest island of the Dodecanese" , "Hordes go to the Greek island" , "Greek island, ten miles off the Turkish coast" , "Hordes visit the Greek island" .)
