DXRC QSL-card Design School Delta-Xray Radio Club has made a set of Guidelines, in order to support our members when designing and printing QSL-cards. At this page we present a list of "things" that we believe should be remembered while designing a good QSL-card. In order to be as precise for you as possible the information is divided into two sections: - Section A: Personal QSL-cards - click here. - Section B: Activity QSL-cards - click here.
