It turns out I DID work Z81X the first night, Nov. 17, after all. The online log I looked at had only been up to 10pm on the 17th and I worked him just before midnight. I saw other QSO’s after midnight in the log and assumed the log was more up to date than it really was. Today the log shows both of my QSO’s, the 17th and the 18th. Nice. I used Club log request a card, for $4.00.
