One of the blogs that I've been enjoying recently has been Roger, G3XBM's and in particular, following his quest to be heard over a distance of 1000 kms on 1mW of WSPR on the 500khz 'band'. He's doing well and has been heard up to 990kms by DL4RAJ but getting a report from over 1000kms is proving elusive!
Roger hints that he might not be running his 500khz WSPR system many more times this winter, so is keen to try and get as many people as possible to listen for him. Can you listen on 500khz on WSPR? Are you in Poland, Austria, Czech Republic or Sweden? Could you leave your receiver running on 503.900khz overnight for the next few nights? Have a go - it would be great to help Roger break the 1000kms barrier. Actually, even if you're not in those countries and fancy listening - why not give it a go, Roger will be pleased to get your report!
Actually, I wonder whether there is any possibility of some greyline propagation at UK sunrise which might help break the barrier?
Either way, it's a fascinating experiment - good luck, Roger!
