6m - more GDX today

6m GDX has again been good today. M0EMM (192km), G4TZX (146km), G8ECI (122km),  G3XGS (65km),  G6AVK (78km) and G4VXE (136km) copied today. In all, quite a number of GDX stations either copying my 1W ERP or being copied here over the last few days.  Some of these are helped by aircraft but almost certainly copyable by plain tropo. I wonder if there has been a small lift on 6m tropo or if this is range under normal conditions?

Sunspot count is 56 and 20-30MHz propagation "normal".
