I think my WSJT-X installation must have had its wires crossed. Or more likely it was a prank. I often monitor the 6m FT8 frequency and suddenly up pops A36WVE/R at a reasonable strength. Being an optimist I made a few calls then thought ... wait a minute.... that's a bit too optimistic! I note that the call is not in the QRZ directory... and the grid square is wrong I think... Kinda hard to read this photo for some reason - it was at about 1820Z Maybe it was a ropey decode - I note the question mark before a1 Tonga And I am using a 6BTV on 6m!
