Add GridLoc from LatLon
Although an ADIF log can include a Grid Locator value, a Cabrillo log does not, except for certain specific contests where the Grid Locator is used in the contest-exchange. You can, though, choose to add a Grid Locator to each QSO in a log that already has a position value, by using this command. If you want to add a Grid Locator to a single QSO, then right-click that QSO and choose the 'Add GridLoc from LatLon' option.
