'broadcasts' is the definition.
(I know this)

'maiden in tristan's wacky' is the wordplay.
I cannot quite see how this works, but
'maiden' could be 'm' (cricket abbreviation) and 'm' is found in the answer.
an anagram of 'tristan' is 'transit' which is present in the remaining letters.
A single letter 's' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
