Interesting commentary on the Heard Island QSO break-out.  I have
one question; Did these numbers get broken out by call sign or from
where the station actually operated.  In other words, if a N2CKZ worked
Heard from Illinois, was that listed in the W9 or Central US
category or simply credited as a W2?  Inquiring minds need to know.

73, and good hunting,
