Going back a two or three years now.
I worked George GM3OXX he was 599+ running 1 watt no QSB at all at my QTH Nr. Manchester... that night I was hearing what I think was 'back scatter', weak watery signals from the South coast of England, can't recall the time but it was around 10 O'clock in the evening.
The first time I've ever heard a GM on 20mtrs and I'd been a swl many, many blue moons ago before getting my license, his signal was incredible.
