Topband: KZ5 again (slightly off topic)

[Steve HA0DU]

Gentlemen,

I just found an old e-mail in which Bob K3UL says thanks for info on KZ5FR.

Now I have a similar problem, but bigger.

I worked KZ5PW Pete Witcosky in 1975, and due to the direct QSLing 
restrictions of that era in Hungary, I was unable to get the card. 
Unfortunately Pete died in 1976 in a helicopter crash, and his wife died 
in the early 2000's. His daughter knows nothing about "the radio thing" 
(as she was only 2 when her father died).

Can someone offer any help? I sent e-mail to K4SQR but it was left 
unanswered. I contacted K4IU (ex-KZ5FR) but he cannot help.
