They seem like two very different technologies, right? They are certainly at opposite ends of the speed spectrum. But David, EA1FAQ, has made innovative use of YouTube video to present -- in a very useful form -- the signals received by his QRSS grabber over a three day period. This kind of system brings to to visual QRSS a bit of the retrivabililty that makes WSPR so useful and interesting.
David's test period happened to include the time that I was out at our country place with my 3 mW QRSS beacon. Back in Rome I could indeed see my sigs in David's video. He was kind enough to follow up with the actual shanpshot of my signal crossing the Med:
Brilliant! Thanks to David for that. What a great way to visualize changing propagation and activity. I'd love to see that done across Field Day.

What band is this? How was this video capture done? Thanks, David
