In depth
A closer look at VOAProp
VOAProp shows you typical propagation for a given hour of the day during a given month. The propagation is shown as expected signal strengths to be received from different parts of the world, plotted on a world map. VOAProp can also display daily point-to-point propagation charts showing the best frequency and time of day for communication with a particular location. VOAProp includes a table of smoothed sunspot number (SSN) data going back to the year 1900. This data is used by VOACAP to produce a plot of average expected propagation for the time of day. VOAProp can also obtain real-time solar data from WWV, which it uses to give a qualitative assessment of conditions. This can show whether conditions are likely to be better or worse than predicted.
