I am not a QSL bureau member and do not send QSLs direct. Therefore my QSOs can be confirmed only by electronically. Actually, I do not have any printed QSL cards neither my own nor received ones.
There are various ways in enjoying ham radio. I am not a card collector or award chaser, but the number of entities could be some indication of my activities.
Obviously, there is a lot of room to keep me interested in this wonderful hobby for a very long time.
