DXbase provides the most comprehensive summary data around when it comes to knowing about your worked/confirmed standings.  Depicted below is the Summary window in DXbase.  The information in this window is automatically updated when a DX spot arrives, when you click on a spot or on a QSO in your log, or when you enter a value to find.  The blue box shows you instantly whether you have a country worked or confirmed by band and mode combination.  Click on one of miniature boxes in this blue portion and you immediately see a list of all QSOs for that category.  For example, all QSOs on 15 meter Phone with VP6D.  Click on a band button and see all QSOs for that band, and so forth.  Finding information is easy in DXbase.  Click on a short or long path and watch your computer controlled rotor turn to that heading!  The summary window lets you select from many different categories such as HF-Country, VHF country, CQ zones, Gridsquares, WPX, and more.  If you click on a QSO or when a DX spot arrives, notes you may have entered for the call sign are automatically displayed in the lower right of the Summary window.  You also see all past QSOs with this callsign displayed in the dockable previous QSO toolbar.  DXbase may not work the station for you, but once you do, it will certainly tell you everything you need to know!
