What is PropNET?

posted Aug 5, 2013, 9:27 AM by Stones River

PropNET is the name given to an innovative project that uses PSK31 to create an RF-based digital peer-to-peer network. Participants simply download PropNetPSK (a Windows program), enter a few station-specific parameters in order to take part.

Most PropNET participants automatically identify themselves over-the-air, typically a few times an hour and pass traffic to other participants. If a receiving PropNET station “catches” (decodes) the transmission, the details are logged locally and the event is plotted on a local map. If the receiving station is connected to the Internet, the “catch” is also reported to a globally accessible website ( The process repeats over time, resulting in a significant amount of network-exchanged information that can be used for many purposes, including the observation of ones own transmission quality (see the FAQ on IMD).
