Weak Signal Propagation Reporter tests

I’ve recently made some experiments with the great WSPR software, which can dig out and process so weak signals that you can’t even hear. Along with the software, there’s a great web interface on which you can see the contacts on a map.

The software receives and transmits automatically, just don’t forget to synchronize your clock and uncheck the IDLE box.

Half an hour after my first attempt to use the software, I was heard from Australia with only 5W output power, and I heard the other station, too:

The bending lines in the spectrum show that the local oscillator’s stability in our old Yaesu FT-757 is not too good.
