Like some old Peruvians ready to broadcast? (5)
I believe the answer is:
incan
This clue is a double definition.
'like some old peruvians' is the first definition.
(the Inca were a historical people of Peru)
'ready to broadcast?' is the second definition.
('in the can' means on tape)
(Other definitions for incan that I've seen before include "Of an ancient civilisation" , "Royal Family member" , "One of the old people" , "Relating to ancient South Americans" , "Former tribesman" .)
