This was all working before a hard drive crash. After a restore, it seems that all is working well except for the jtalert logging to dxkeeper.
No alerts seem to show up on jtalert and when I log a QSO in FT8, it seems nothing gets passed to dxkeeper.
+ When you're using JT-Alert, DXLab applications are relatively passive: they receive directives - like "lookup callsign" and "log QSO" from JT-Alert, and then execute them.
+ Focus first on getting JT-Alert to correctly interoperate with WSJT-X. When that's working, then configure JT-Alert to correctly interoperate - one at a time -- with DXKeeper, DXView, SpotCollector, and Pathfidner.
