One of the best tools for understanding 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.
For amateur radio uses (HamRadio), World globe and maps, with live/realtime MUF maximum usable frequency, foF2 and Aurora Borealis layer. Tell distances, directions of antennas.
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 about the past, current and future band conditions.
This page only contains "live" links to online receivers! The links below will actually take you to sites where you can listen to amateur radio communicating with each other around the world. The "live" links will let you hear ham radio operators using every imaginable mode of 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.
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.
