In the mail today I received a QSL (confirmation) card from EP2MKO, a station I worked in Iran. It's not often you can work a station in Iran, and even more difficult to get a confirmation.
This contact took place several years ago, and I had sent a request (my own card) but never received a reply. Recently I found a new updated email address for the operator -- a Russian who was operating from Iran -- and re-sent my request to him.
I have sent a QSL to PJ4LS in the Netherland Antillies for our recent contact, which will be country #311 for me, and put K6CU on the DXCC Honor Roll!
