WSPR Rocks

This is an excellent site. With it, you can see WSPR spots as maps and look back easily over the last 5 weeks. 

Yesterday, using SQL, the owner (Phil VK7JJ) kindly showed me how to go back to 2008! I had been hoping to use it to do a map of all my 500uW spots, but then I realised the snag! 

My little beacon is pre-programmed to report all spots as 500mW, so spots with the PA off (500uW) cannot be distinguished if over 5 weeks old. In the last 5 weeks I have, as an experiment, just been running 500uW (0.5mW). It has been an eye opener.

Roger, is it possible to do a post about how to get back to 2008 with SQL on WSPR rocks? I would be interested. I've been looking at it but do not know what to do. 73, Bas
