Going off right away - doing this to find a station (6)
I believe the answer is:
tuning
'doing this to find a station' is the definition.
(I've seen this before)
'going off right away' is the wordplay.
'going off' becomes 'turning' (eg rotting food turns or goes off).
'right' becomes 'r' (common abbreviation).
'away' indicates named letters should be taken away.
'turning' with 'r' taken away is 'TUNING'.
(Other definitions for tuning that I've seen before include "Calibrating to a standard frequency" , "Correcting musical pitch" , "Adjustment (which can be fine)" , "Calibrating a musical instrument" , "This fork is used ot adjust piano" .)
