Gossip about the dial moving round (4,4)

'the dial moving round' is the definition.
I know nothing about this answer so I can't tell whether this works.

'gossip' is the wordplay.
I cannot really understand how this works, but
'gossip' could be 'chat' (synonyms) and 'chat' is located in the answer.
The remaining letters 'idle' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

'about' acts as a link.

Can you help me to learn more?
