Scheduled next in line for radio broadcasting? (2,3)
I believe the answer is:
on air
'broadcasting?' is the definition.
(broadcasting on the air)
'scheduled next in line for radio' is the wordplay.
I cannot really see how this works, but
'scheduled' could be 'on' (I've seen this in other clues) and 'on' is located in the answer.
'line' could be 'air' (synonyms) and 'air' is found in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for on air that I've seen before include "Broadcasting at this moment" , "In the process of broadcasting on radio or TV" , "Radio show might be" , "Currently broadcasting" , "In the act of broadcasting" .)
