MUF Predictor

MUF Predictor


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.

Although the algorithms used in MicroMUF have some limitations compared to other more advanced algorithms (like IONCAP), the calculations are very accurate for everyday use in the HF range (2-30Mhz).

The application contains the complete and updated DXCC countries list, so that you do not have to enter latitude/longitude but type directly the DXCC prefix or country name for the transmitter and receiver location, while the SSN is retrieved automatically from NOAA site if required.

Most often used propagation paths can be saved so that a prediction can run on them later.There is no limit to the number of paths stored into the application.

Using a single location option for the whole continental U.S. is just wrong. California and Maine are not going to be the same, but they are to this app.

Add more areas to the larger countries This app works great on my Samsung Note 10.1. The only thing is to add more areas to the larger countries such as Russian Federation, Canada, China, Brazil and the USA.
