472kHz WSPR unique reports over last 2 weeks

Looking at the results over the last 2 weeks, I see that I've had reports of my 5mW ERP (15m spaced earth-electrodes) from 8 different stations. Best DX is F1AFJ at 607km followed by reports from 3 different Dutch stations. I'll leave the set-up running overnight in case I get any new stations reporting me.
