What you're suggesting does not do what I am looking for. First off, it's just a report, not a way to filter the log for queuing QSL labels for print.?
Secondly, it includes grids that have already been confirmed via LoTW by other stations. If a grid has been confirmed via LoTW or paper card in the past then any log filter or report should not include that grid, even if there's a non-LoTW user in it that hasn't confirmed my QSO. I don't need that grid confirmed again.
The goal is to filter the log in such a way that the only QSOs displayed should be for 6m (only) grids not confirmed already via LoTW or paper card. That is the predominant search criteria.
If a grid has one or more unconfirmed QSOs, then I need to filter the display to show every station I've worked within that grid who does not use LoTW so I can create a label and send him/her a physical card. Do this for every unconfirmed zone. Eventually I will have sent physical cards to non-LOTW stations. Once I do that, I will need to filter the log again to include unconfirmed grids where I've worked LoTW-participating stations, so I can email them and see if maybe they busted my call or whatnot, or if I'm NIL, then mark those QSOs invalid in my log.
I use FFMA since it's a subset of all unconfirmed 6m grids, and it takes the band variable out of the equation. But in reality, I want to do this for?all unconfirmed 6m grids, US or international.
