WSPR is a great propagation testing tool and we've had a lot of activity on 630 m of late. I'd like to extract as much information from the WSPR data as possible so I've been copying selected data from the WSPRnet data base, pasting it into an Excel spreadsheet and the massaging it a bit. It's been interesting and I've written up a short note on this work to date: Download WSPR data with Excel . 73, Rudy
