Introduction to HF Radio Propagation
Australia's IPS Radio & Space Services provides a nicely organized overview of HF radio propagation theory. Images and graphs enhance the presentation.
NCDXF/IARU Beacon Transmission Schedule
Near-Real-Time MUF Map (Solar Terrestrial Dispatch)
Offers a wealth of propagation prediction information, graphically presented, including: Radio Auroral Zones; MUF contour lines; Grayline. The map is updated every five minutes.
Realtime Propagation Monitor
By LA7SL, shows important solar, ionospheric, and geomagnetic information useful in calculating and predicting present and near future radio-propagation. "DX Summit" DX spots and propagation bulletins are also provided.
