MUF(3000km) - kc2g.com
MUF is the highest frequency that is expected to bounce off of the ionosphere on a path 3000km long. So the MUF along a path between two points shows the possibility of long-hop DX between those points on a given band. If the MUF is 12MHz, then 30 meters and longer will work, but 20 meters and shorter won't.

MUF Propagation Map
Maximum usable frequency (MUF) is the highest radio frequency that supports communication between two points on Earth by reflection from the ionosphere (skywave or skip) at a specified time, independent of transmitter power.
HF Propagation Map
Maximum usable frequence (MUF) is the highest frequency that supports communication between two points. On this map, MUF can be considered the maximum used frequency, since the display is based on real-time data. Data for the map is gathered from several online sources: WSPRnet, Reverse Beacon Network (CW, FT4, FT8), and DX Cluster.
Real-time MUF Map
Read more about Real-time MUF Map. The project "Understanding HF Propagation" provides a detailed overview and tutorials on HF propagation. The best real-time radio propagation map is based on MUF data.

The following map shows Maximum Usable Frequencies (MUFs) for 3000 kilometer radio signal paths. The grey line position is also provided. Image courtesy of the KC2G propaation pages. Current Sun Images. The images below are current views of the sun shown at different wavelengths of light as taken by SOHO and the Yohkoh soft-Xray telescope.
Live HF Propagation Chart / Map
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 …

3 天之前 — 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. Frequency: MHz foF2: MHz hmf2: km Calculated Skip Zone: km miles.
Maximum usable frequency - Wikipedia
In radio transmission, maximum usable frequency (MUF) is the highest radio frequency that can be used for transmission between two points on Earth by reflection from the ionosphere (skywave or skip) at a specified time, independent of transmitter power.
