why do you ask, did you hear a call from 343Div?
Its not impossible, but at the moment highly unlikely.
If there was a activation from the island most 11m dx hunters would be on it like flys
looking Dx proofs its stated as very rare, with no activation's on 11m.
This time of the year & taking into the conditions South America is as far away as you are likely to reach at the moment. (info taken from cluster.nl)
If you did hear a call, its either going to be a) fake b)34div mistake.
