Many changing cutting edge broadcast for satellite (8)
I believe the answer is:
ganymede
'for satellite' is the definition.
(I've seen this before)
'many changing cutting edge broadcast' is the wordplay.
'changing' is an anagram indicator.
'cutting' means one lot of letters goes inside another (some letters cut their way into a word).
'broadcast' is an anagram indicator (letters scattered or cast around).
'many' with letters rearranged gives 'anym'.
'edge' is an anagram of 'gede'.
'anym' put inside 'gede' is 'GANYMEDE'.
(Other definitions for ganymede that I've seen before include "heavenly body seen by Jupiter" , "Jupiter's largest moon" , "One of Jupiter's moons" , "Beautiful youth" , "beautiful boy" .)
