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 is the new home page for the WSPR community. You can still easily get to the Sked/Chat page and the database page via the links on the left, but here we can also post articles, reference information, have forum discussions, etc. If you are an amateur radio operator using WSPR or interested in it, please register an account for yourself using your call sign as the login name.

Eventually, the Sked and Database features of this site will all be integrated under this framework.
