Time on the radio tackling Duke is making spectacular show (3,7)

'time on the radio tackling' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'duke is making spectacular show' is the wordplay.
I cannot quite see how this works, but
'duke' could be 'd' (abbreviation) and 'd' is found within the answer.
'is' is found in the answer.
'show' could be 'play' (play is a kind of show) and 'play' is present in the answer.
The remaining letters 'air' 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).

Can you help me to learn more?
