How radio waves propagate in other than straight-line paths is a complicated subject, but one that need not be a mystery. This page provides basic understanding of the principles of electromagnetic radiation, the structure of the Earth’s atmosphere and solar-terrestrial interactions necessary for a working knowledge of radio propagation. More . HF propagation prediction is a statistical science. The maximum usable frequency (MUF) is the highest frequency that, with a probability of 50% of the time, can be used for radio communication between two points at a specified distance (but not necessary in all directions) via refraction by the ionosphere. Amateur radio propagation modes used. One of the interesting aspects of ham radio, is the enormous variety of different propagating modes that can be used. The band, time of day, time of year, weather and position in the sunspot cycle can all have an effect, dependent upon the type of propagation mode used. So, when the sunspots return in force, probably around 2024, you're going to hear a lot of talk about SSB on 10 meters again. Until then, the propagation you're currently experiencing is fairly "normal" without sunspots, and your best bet might be to check out the digital modes.

    On-Line HF Propagation Prediction

    HF propagation prediction is a statistical science. The maximum usable frequency (MUF) is the highest frequency that, with a probability of 50% of the time, can be used for radio communication between two points at a specified distance (but not necessary in all directions) via refraction by the ionosphere. A simple application to assist ham radio operators in everyday HF propagation prediction.The application calculates MUF (Maximum Usable Frequency) and LUF (Lowest Usable Frequency) to any location in the world based on SSN data. The application is based on MicroMUF, developed in 1984 by Raymond Fricker from BBC External Service.
