Band chat on radio (4)
I believe the answer is:
torc
'band' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for torc that I've seen before include "Rigid circular necklace" , "Choker" , "One gets into a twist" , "Twisted metal neck band" , "Metallic neck ornament" .)
