TV channel in an uplifted state (6)
I believe the answer is:
nevada
'state' is the definition.
(Nevada is an example)
'tv channel in an uplifted' is the wordplay.
'tv channel' becomes 'Dave' (UK TV channel).
'in' is an insertion indicator.
'uplifted' says the letters should be written in reverse.
'dave' going inside 'an' is 'adaven'.
'adaven' back-to-front is 'NEVADA'.
(Other definitions for nevada that I've seen before include "State of western USA" , "Western US state" , "US desert state" , "State including Las Vegas" , "part of US" .)
