Radio: Chris heard latest broadcast (7,3)
I believe the answer is:
crystal set
'radio chris' is the definition.
'crystal set' can be an answer for 'radio' (thesaurus). I'm unsure of the 'chris' bit.
'heard latest broadcast' is the wordplay.
'heard' becomes 'crys' (I can't explain this - if you can you should give a lot more credence to this answer).
'broadcast' is an anagram indicator.
'latest' anagrammed gives 'talset'.
'crys'+'talset'='CRYSTAL SET'
Can you help me to learn more?
(Other definitions for crystal set that I've seen before include "Radio" , "Receiver" , "used to receive long ago" , "Matching glasses" , "matching items of glassware?" .)
