I have had a couple of cases recently where a QSL manager has not seen that I have 2 QSO's on my QSL, and I only get 1 QSO confirmed. I put "2 QSOs" on it and underline it. What is the best way to get the manager's attention on the card? Highlighter? Or, should I just send 1 QSO per card? Tnx & 73, Tim K6GEP
