What is a QSL Card?


     A QSL card is a specially designed postcard that hams exchange in the mail whenever they make contact with one another for the first time. Hams exchange cards in friendship and to prove that they actually made radio contact.

     Each ham’s QSL card has a unique design that may include words and pictures about his or her family, friends,  and places that are special to them.       

     The cards also include information about the ham’s call sign,  radio contact equipment, date, time and type of contact,  and geographic location of the ham.

     Almost every QSL card has the number 73 on it.  Do you know what 73 means? 

Here are some of the QSL cards that  Dr. Martin Bayes has sent to contacts around the world.  What do you notice about the call signs on the different cards?  What are you wondering?
