More 6m WSPR spots

G8VDQ (93km) seems to be regularly spotted here on 6m WSPR. The last spot was at 1332z. I suspect this is tropo with the influence of aircraft. I suspect it needs aircraft moving in the right positions and directions for the path to "work". The pure tropo path does not seem to be there, otherwise I'd spot him most of the time when he is active on the band.
