JT65 20m 2-way QSO

About 45 minutes ago I worked EA1EAS (1335km) on 20m JT65. This was with the Par tri-band antenna running 5W via the ATU. I received a better report than I gave.  I don't think there is much wrong with the Par antenna and wonder if the wet weather has made it go off tune? The ATU easily corrects the mis-match and it certainly works. From PSK reporter I see than I was being copied all across Europe again.
