2020-05-24 Shared my script to optimize outgoing QSL cards 10 months ago
As a radio amateur I like sending and receiving QSL cards. QSL is the Q-code for "I confirm reception" and a QSL card is the way to confirm a contact. I have my own QSL card design and a big box of cards to send out. With contacts I usually do a check if a fellow amateur mentions the wish for cards via the QSL bureau on her/his qrz.com page, because I only want to send cards to interested amateurs. Due to the way I process my cards I can put up to 4 contacts on one card, so it's a simple optimization that if I have one contact that I want to send a card for I also check for other contacts with the same callsign. The qslmaximizer.pl script does this for the CQRLOG database.
