Got this from Ohio/Penn DX Bulletin :

PJ4, NETHERLANDS ANTILLES. Operators Hal/N4GG, Mayse/W4OC, Mark/N5OT and
Mike/W9RE will be active as PJ4/homecall from Bonaire between February
12-19th. Their activity will include the ARRL CW DX Contest (February
16-17th) as a Multi-2 entry signing PJ4M. Look for operations before and
after the contest. QSL PJ4M via N4GG and all other callsigns via their
home callsigns.

Quite possible you maybe ended up with an extra "dah" in the call sign
during the heat of the contest.

They were definitely signing PJ4O in the contest. At least, *someone* was
signing PJ4O - and they made enough contacts that they pretty much had to
be these guys...

I might educated-guess that this does mean N4GG is the right route for
PJ4O.

I might also educated-guess there was some kind of misunderstanding either
at the PJ4 licensing authority or among these ops (or both) as to what
call would be assigned.
