When we're doing a QSO last action of kindness is to send a QSL card confirming the contact. It' s important not only to remember the QSO done, but also to acquire the credit for awards.
Don't send the QSL card, if an operator is good to send it, means not respect the normal behavor among radioamateurs or radio enthusiasts. I think we have to pay attention and we have to remember last action, after the end of our QSO. Thanks a lot. Angelo I0RNK
