- 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
- Real-time MUF Map
This MUF map is a useful real-time indicator for HF propagation conditions
- 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
- MUF, LUF, and FOT - The Basics of the Maximum Usable Frequency - HF Radio
Basic MUF, being the highest frequency by which a radio wave can propagate between given terminals by ionospheric propagation alone, independent of power The difference in frequency between operational MUF and basic MUF is in practice from ten to thirty-five percent
- HamDXMap - The DXZone
This dynamic DX Map aggregates various resources that will help radio amateurs to operate their stations in search of long distance contacts, DX HamDXMap displays current MUF values and foF2 critical frequency values around the globe
- Maximum Usable Frequency - Skywave Radio
To avoid absorption, we want to operate at the highest frequency possible, that is at the MUF This means operating on 20 through 10 meters during the day MUF drops at night as the ionosphere’s critical frequency declines In addition, the D layer disappears at night making possible long-distance communications on 80 and 40 meters
- MUF Propagation Map
What is MUF? — Maximum usable frequency is the highest possible frequency (HPF) that supports communication between two points on Earth by refraction from the F ionospheric region at a specified time, independent of transmitter power
- CF vs MUF: Understanding Critical and Maximum Usable Frequencies
Maximum Usable Frequency (MUF) is the maximum frequency that can be used for reliable communication between two points via ionospheric reflection, for a specific distance As shown in the MUF formula, it depends on both the critical frequency and the angle of incidence
