I have used three call signs while being a member of qrz.com. The first as a technician, the second when I received my Extra ticket, and the last is a vanity call. When I apply for awards, it only provides the option of the call sign I used when I first received my Extra ticket - it won't allow a change of the call sign to the vanity call sign that I now own (use). The call sign that I had prior to the vanity is now owned (used) by another operator. What is the remedy for this?
