Solar conditions play a crucial role in HF-propagation conditions. RigReference.com has a widget showing the current conditions based on NOAA data. This data can be used by ham radio operators to determine the best time to make long-range communications on shortwave bands (160 to 10 meters).
With this WordPress widget you can now add the solar widget to your blog easy and simple.
- What is HF-propagation?
HF-propagation is the way in which radio waves travel through the earth’s atmosphere. Many different factors influence propagation; time of day, temperature, weather and solar activity.
- On what data is the widget based?
The widget is based on solar-terrestrial data from the National Oceanic and Atmospheric Administration (NOAA). They have a wealth of information available for anyone interested. Among others, they measure solar activity and make it available – as raw text – here: http://www.swpc.noaa.gov/ftpdir/latest/
- What about the widget’s time?
The time in the image indicates the time of the measurement at NOAA. It does not indicate local or server time!
