G8XWR (150km) was just spotted on 6m WSPR. This is an interesting distance and probably by a combination of tropo and aircraft reflection judging by the Doppler on the signal. Of course, the drift could be settling drift and not Doppler at all. Looking at later traces, there is little evidence of aircraft. A couple of strong traces did not decode showing strong QSB and disappearing for a good part of the slot.
UPDATE 1302z: I spotted G8XWR (150km) again a few minutes ago. He was stronger and there was no sign of aircraft involvement with just a single trace with QSB. No 10m WSPR spots yet.
UPDATE 1340z: G8XWR (150km) near Haslemere in IO91oc is getting stronger. If this was via aircraft I'd expect multiple reflections and Doppler but all I see is a single carrier with QSB.
UPDATE 1512z: G8XWR has been spotted 7 times so far. Although there is no evidence of aircraft involvement, Heathrow and Gatwick stacks are nearby.
