Broadcasting duration for tune at tempo (7)
I believe the answer is:
airtime
'broadcasting duration' is the definition.
'airtime' can be an answer for 'duration' (I have seen 'Duration of broadcast ' mean 'airtime' so perhaps 'duration' could also mean 'airtime'). I am unsure of the 'broadcasting' bit.
'tune at tempo' is the wordplay.
'tune' becomes 'air' (air can mean a piece of music).
'at' says to put letters next to each other.
'tempo' becomes 'time' (I've seen this before).
'air'+'time'='AIRTIME'
'for' is the link.
Can you help me to learn more?
(Other definitions for airtime that I've seen before include "Length of a particular broadcast" , "Duration of TV/radio programme" , "Duration of broadcast" , "spell on the waves?" , "Minutes allocated to a broadcaster" .)
