What type of data is reported by amateur radio propagation reporting networks?

Amateur radio propagation reporting networks, such as the Reverse Beacon Network (RBN), WSPRNet, or PSKReporter, operate by monitoring and reporting actual received on-air signals. They are primarily designed to track automated digital-mode transmissions and CW (Morse code) signals. These networks do not directly measure space weather parameters like solar flux or magnetic declination. Instead, they provide practical, real-world data on how well radio signals are currently propagating between specific geographic locations based on the successful decoding of those digital and CW signals.
