I have had my Call Sign for about 5 years, so I consider myself a Toddler of the hobby. As I studied for the Tech exam, I recall, "all you need to know is your own call sign when ending a QSO" Something like "73 my friend, Kilo Mike Six, Charlie November Delta". I do not end it with "73 my friend, Wiskey Alpha three Zulu, Kilo Mike Six, Charlie November Delta". If I am required to end a QSO this way, I must have missed that chapter in the study guide. Is it wrong to acknowledge to Call Sign of the person I'm about to end my QSO with? I don't think so, I just don't roll that way and the biggest "offenders" (if there is such an offense) are those that got their Call Sign's shortly after God got his! Has there been a Cultural Ham Shift over the past decades?
