Broadcast refined git upgraded for the nobs (10)

I believe the answer is:

gentrified

'upgraded for the nobs' is the definition.
(nobs can informally mean upper-class people)

'broadcast refined git' is the wordplay.
'broadcast' is an anagram indicator (letters scattered or cast around).
'refined'+'git'='refinedgit'
'refinedgit' anagrammed gives 'GENTRIFIED'.

(Another definition for gentrified that I've seen is " such an improved area?".)

I've seen this clue in The Times.
