Comment:

Everything you need to know about propagation in an easily understood and clearly explained tutorial from Sean D. Gilbert (G4UCJ). Sean provides helpful maps, graphs, and photos to explain key concepts involved in propagation--the way our radio signals travel through the atmosphere and reach our target areas.

The report has several sections, including:

What is propagation
What are the layers of the atmosphere
What is MUF and the angle of radiation
What are NVIS, groundwave, and skywave
The IARU Beacon System
Multihop signals
Short and Long path propagation
Grey Line propagation
Sunspots and the solar cycle
Sporatic E and Backscatter
A & K Indices
Flares, geomagnetic storms, and CMEs
Sudden Ionospheric Disturbances and Polar Cap Absorption
A list of beacon stations and general propagation characteristics of HF bands.

Download the complete study and keep it in your reference library.
