  No he can't. The light pulses sent by the external observer won't ever
reach the falling object, from the external observer's point of view, for
the exact same reason that it looks to him like the falling object never
crosses the EH.

  The falling object won't be able to send anything back because he is
inside the EH.

  Of course he has.
