Many dx-peditions don’t expect paper QSL cards any longer. They will provide an Online QSL Request System (OQRS), where you can request your QSL cards without sending your own. Club Log has great features supporting this.
When you have requested your QSL via an OQRS, you can mark the affected QSOs using Menu–>QSL–>Mark as ‘QSL requested’. The status changes to Q.
A QSL label will not be printed now, even you get your QSL!
