According to tropo forecasts, there is remote chance of transatlatic tropo on 2m early this week between Canada and western Europe. There are people trying on FT8. As far as I am aware we have never had a transatlantic QSO on 2m in the North. People have spanned from Cape Verde to the Carribean. FT8 is a good mode to try as it works with very weak signals. Crossing the North Atlantic with 2m tropo is a very long way!
