If I use my laptop without wifi the caller’s QTH does not populate. Of course. But is there a way to lookup the callsign when I get back in to the shack without having to lookup each contact separately?
Unfortunately, at the moment you can’t do this.
Earlier releases of the HAMRS app, prior to version 1.0, had a “lookup all” feature but there were problems with it that, on rare occasion, led to data loss. So it was removed.
I’m not sure if @jarrett has plans to bring it back or not. I think it would be a time-saver and would like to see it, too.
