Here some analysis of my recorded spots data with my spot data collector. As of today there are 45.000 spots recorded in my database.
Inspired from some work found on the Internet and the full functionality of my U3S I've build an automatic spot collector. The spot collector pulls every 5 minutes my spots from WSPRnet.org and puts it into a MYSQL database for later analysis. See the schematic for this setup
The spectrum is measured using an ELAD FDM-S2 receiver.
