The median signal levels are compared with monthly-median signal-level predictions generated using VOACAP and ASAPS HF prediction software with the emphasis on the NVIS links. Low rms differences between measurements and predictions for September/October/November and also March are observed. However, ...

Prediction of Jupiter Radio Bursts/Storms can be calculated and displayed. These storms can be heard on the upper end of the shortwave band. You can also connect to your favorite DX Cluster, to read and send DX tips in real time. The following radio propagation reports and forecasts are ...
HF propagation prediction is a statistical science.The maximum usable frequency (MUF) is the highest frequency that, with a probability of 50% of the time, can be used for radio communication between two points at a specified distance (but not necessary in all directions) via refraction by ...
