Obscure? Easily picked up within borders of country (6)
I believe the answer is:
cloudy
'obscure?' is the definition.
(I've seen this before)
'easily picked up within borders of country' is the wordplay.
'easily picked up' becomes 'loud' (easy to hear or 'pick up').
'within' is an insertion indicator.
'borders of' means to remove the middle letters.
'country' with its centre removed is 'cy'.
'loud' going inside 'cy' is 'CLOUDY'.
(Other definitions for cloudy that I've seen before include "Obscure" , "'Overcast, nebulous (6)'" , "Murky or nebulous" , "Blurred" , "(Of a liquid) not clear" .)
