This map shows real-time radio propagation from stations operating on 11 bands between 1.8 and 54 MHz in the amateur radio service. The display shows worldwide activity from the last 15 minutes and is automatically updated about every minute.

One of the best tools to forecast HF (high-frequency) propagation is the online map (chart) shown below. It is a graphical representation of MUF within a 3000-kilometer range, allowing amateur radio station operators to estimate the best frequencies and paths for effective communication.

Below you will find charts showing the live conditions around the Earth for radio propagation as well as atmospheric conditions that can affect Ham Radio usage depending on frequency. These are great tools for HF and knowing what the conditions are if you plan on trying to make contacts on a particular day/time.

HF Band Conditions maps are powerful tools used by amateur radio operators, shortwave listeners, and radio enthusiasts to monitor and predict the state of high-frequency (HF) radio propagation. These maps provide valuable information …

The project "Understanding HF Propagation" provides a detailed overview and tutorials on HF propagation. This MUF map is a useful real-time indicator for HF propagation conditions.

5 天之前 · For a point to point propagation prediction that depicts probabilities for each band and allows for determining the best frequency and best time to make a long distance HF contact, please see VOACAP Online.

1 天前 · Find the foF2 and hmF2 graph closest to your location, and enter in the current values, (the end of the blue trace) along with the transmitter frequency. The estimated skip zone will be calculated. The skip zone does not exist if the foF2 value is larger than the frequency.

This map shows real-time radio propagation from stations operating on 11 bands between 1.8 and 54 MHz in the amateur radio service. The display shows world-wide activity from the last 15 minutes and is automatically updated about every minute.

Clickable overview of solar activity influencing HF propagation on Earth. Onset times are measured from the occurrence at the Sun’s surface. The mathematical symbol ∩ stands for intersection.
