We succeded, W8IJK/KC4 is WAP USA-51!
Decisive has been the help of Scott WA4TTK who did provide his QSL of the contact with Jim Collinson W8IJK/KC4.
We sent a mail to Scott, since as far as we know, he was one of the few Hams who have worked W8IJK/KC4 from Shackleton Field Camp, Antarctica, long ago.
We explained Scott that, Shackleton Field Camp was in the process to get a new WAP reference number (which is normally issued after completing the investigation; one of the item is to get a date of activity which qualifies the authenticity of the operation).
By a quick return, we get a kind reply from Scott WA4TTK who wrote:
Hello Gianni,
Yes, I certainly remember that QSL card. It is a fantastic photograph of the Queen Maud mountain range and I have admired it since the day I received it.
The QSO was made on December 4, 1978 at 0743 UTC on 14.311 MHz. A scan of my QSL card is attached to this email.
I hope this helps in getting your new WAP reference number. Please let me know if I can be of any assistance.
73, Scott Craig, WA4TTK — Nashville, TN — USA

We would like to express our gratitude to Olivier F6EPN, to Bob K4MZU and to Scott Craig WA4TTK for their invaluable help without of which, we would have struggled a lot to have the evidence we were looking for, to issue the reference!
