IPS - HF Systems MUF maps and prediction charts
These pages provide general propagation advice for HF communicators. Information available includes inferred global propagation conditions, real time HF fadeout coverage charts, regional ionospheric vertical MUF maps and Hourly Area Prediction charts for Astralia and Asia, Europe and North America
-
Near-Realtime MUF indicator
This is a highly informative map that can be used by amateur and professional radio communicators to determine maximum usable frequencies for any world-wide path at the indicated UTC (Zulu) time.

Real time sunspots number
Space Weather: Real-Time 24hr Effective Sunspot Number
-
DX.QSL.NET Propagation
This page contains dynamically updated propagation information.
-
Antennas and Propagation
The most important element in a radio circuit is the antenna. You may have a powerful transmitter and a frequency, but without the correct antenna, communication will be less than desirable, if not impossible.
This subcourse provides information necessary to make the right choice for an antenna and how to select the correct frequency depending upon the environmental conditions.
Without an understanding of wave propagation, decisions on frequency selection and antennas could result in no communications.

NASA Sunspot Cycle Predictions
Nasa MSFC predictions on the behavior of current sunspot cycle.
-
D-Region Absorption Prediction
This map represent the current position of the sun and how a solar flare influence an HF fade. Estimated recovery time is also represented. Includes son java and javascript animations of last two hour conditions
-
NOAA Space Weather Scales
The NOAA Space Weather Scales were introduced as a way to communicate to the general public the current and future space weather conditions and their possible effects on people and systems.
The scales describe the environmental disturbances for three event types: geomagnetic storms, solar radiation storms, and radio blackouts.
