WSPRnet – Weak Signal Propagation Reporter Network (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.)
Proppy – HF Propagation Prediction – The tools provided by this web application enable users to predict available frequencies, signal levels and corresponding reliabilities for High Frequency (HF) circuits. All predictions are performed using the ITU’s ITURHFPROP application; a software method for the prediction of the performance of HF circuits in accordance with Recommendation ITU-R P.533-13.
ReverseBeacon – The Reverse Beacon Network is a revolutionary new idea. Instead of beacons actively transmitting signals, the RBN is a network of stations listening to the bands and reporting what stations they hear, when and how well.
