QSL cards
This is more to educate everyone. I see a lot of listings under QSL cards that are not QSL cards. They are CB radio cards. A QSL card is for amateur or " ham radio ". Requires a license and an FCC issued call sign. Some operators have vanity call signs they have requested from the FCC. An example would be KF0JZR, my call sign. CB requires no license and therefore no issued call sign. Most likely have the operators handle instead.
