The QSL cards are generic in that they have a blank section across the top of the front view. This is where you would write, type or print your own callsign. You could setup a template in a word processor and easily print your callsign on each card.
We have purchased many cards and they are available for sale for a nominal cost to all club members. Anyone interested in purchasing QSL cards, please contact Ken McCormick VY2RU
