I've been into HF operations for only about six weeks now, but I have faithfully mailed out paper QSL cards to every contact
My response? Only five have returned the favor
(sad, I think, that a ham who can afford to spend $15,000 on equipment is unable to afford a roll of stamps),
Is QSLing a thing of the past? I wish now that I hadn't bought so many cards from the printer....
Seriously? You have been making HF contacts for a whopping month and a half and you have already determined that QSLing is a thing of the past just because you have only received 5 cards back?
And the other 35 that have not yet sent you their card in return... how do you know they have $15,000 worth of equipment?
But to actually answer your question, QSLing
with paper cards is pretty much a thing of the past mainly because of the cost and especially now that there are electronic alternatives. If you are looking for a memento on paper of the individual contacts you have made, I think you are going to be disappointed. Sorry.
If, however, you want to earn awards such as the ARRL's DXCC and WAS, then you should get on board with LoTW (Logbook of The World):
Logbook of the World. You may hear people say what a PITA it is to set up LoTW... and they are right! But once you have jumped through all of the hoops, it is incredibly easy to use, especially if you use an electronic logbook that supports uploading to LoTW like Ham Radio Deluxe (aka HRD).
The other major player in the electronic confirmation arena is eQSL:
eQSL.cc - The Electronic QSL Card Centre. It is much easier to set up and use. The bad news is that eQSL confirmations do not count towards the ARRL awards, but eQSL has many of their own awards.
And while I am on my soap box, another virtue in the world of QSLing is patience.
Here is a screen shot of one page of my LoTW confirmations:
Look at the one circled in red. That is a confirmation of a contact I had over 20 years ago! Don't get your underwear all bunched up because you don't receive a confirmation in a week or two.If you are skillful (or lucky) enough to work a major DXPedition, it can take months to get a confirmation... even an electronic one. And if you use the incoming and outgoing QSL bureau, it can take YEARS to get a paper confirmation!
Good luck and oh, by the way.... Welcome to Amateur Radio!
