eQSL (what is it?)
The best way to exchange a QSL today is the eQSL. It is free, safe and fast.
It does not need any space and you can carry it with you, e.g. on your smartphone. You can send them by e-mail or you save your eQSL in the DXcluster, where a QSO is automatically confirmed with it, provided that the other station is also registered there with its own card. For Romeo Charlie members it’s standard to confirm via eQSL; non-RC operators have the possibility to get confirmation as eQSL too.
If you’re a registered member of a DXcluster like clusterdx.nl, 11dx.net or dx27.net you can design your own eQSL and store it there.
Usually different sizes and formats are used, e.g.:
