The Weak Signal Propagation Reporter Network is a group of amateur radio operators using K1JT's MEPT_JT digital mode to probe radio frequency propagation conditions using very low power (QRP/QRPp) transmissions. The software is open source, and the data collected are available to the public through this site.
This looks like a fun new activity for hams. Even non licensed folks can listen? You will need a radio and USB type of soundcard like the Signalink USB. I set mine up with the FT-857 and with this software it has CAT ablility so it's pretty much hands free and let it run! The first day was a Satirday afternoon and I had good results. Several DX stations heard me and I heard them! I attached below a screenshot from day 1. After this screen grab I also reached 2 in Italy.
