With just a bit of effort, it was possible to put WSPR data (with a timestamp) into Google Earth -- creating a time-lapse representation of WSPR data. This video shows 24 hours of K7ZOO as received across CONUS, starting and ending at 3am local time. Red data points are 40 meters; White data points are 20 meters. The diameter of the data points is scaled to the received signal level. de K7ZOO
