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.

My WSPR data collector is now running some days and I started with some basic data analysis.

The power on the bands 60m to 20m is about 100mW!

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 and puts it into a MYSQL database for later analysis. See the schematic for this setup Wspr V3

Measurement of the signal quality of QRP-Labs U3s with low-pass filters.Transmitter output is fed into a homemade 20dB pad and an additional 30dB pad from miniCircuits.

The spectrum is measured using an ELAD FDM-S2 receiver.

My new U3S is online :-)
