28MHz WSPR Day

It’s ages since I played with WSPR, but inspired by Julian G4ILO’s 28MHz WSPR results I thought I would give it a go.
I set the rig up with about 1 Watt out – a little over but I have quite a long feeder run to the Butternut. To start with, I doubted that it was working but then I heard G0MGM and he heard me – so it was obviously working!
Left things running throughout the day. My most distant report seemed to be around 3600km away; UA6AAK and 4X1RF around the same sort of distance. Some great reports from EA8FF in the latter part of the day.
Heard LU and T5 – but my 1W didn’t get that far today!
Fun experiment which I will repeat!
Pardon my stupidity but what exactly IS wspr?
