If I work a number of stations during a contest, but I don’t plan to mail out QSL cards to everybody I worked and I want to change QSL Sent to “N” in one move how do I do it?? I know that I go into the DXKeeper Advanced Sorts, Filters & Modifiers.? Then create a Filter to isolate them.? Finally, under “Modify QSOs in Log Play Display I set QSL_Sent to “N”.? The question is what would the filter look like?
