I send a QSL-card via the bureau and via eQSL.
In some special cases i will sent direct.
I choose also for the electronic way because its fast ! And i believe its also save. This is all hobby and those people who want to cheat are not really radio-amateurs.
So also check for your(my) qsl-card on esqsl.cc
All QSO's will be confirmed ( contests included ! ) Please return a QSL-card by the bureau and/or eQSL.
