Broadcasts small tips (5)
I believe the answer is:
'broadcasts' is the definition.
(I know this)
'small tips' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'tips' becomes 'ends' (I've seen this in another clue).
(Other definitions for sends that I've seen before include "Causes to go somewhere" , "Transmits" , "Despatches" .)
