ITURHFProp Propagation Prediction

An introduction to G4FKH’s new propagation predictions tool

RadCom readers may be aware of Gwyn G4FKH’s new HF propagation prediction project, software and website based on a new prediction engine.

The project’s aim is to produce a propagation prediction tool that uses the new ITU-produced program ITURHFProp, which has been shown to be more accurate than older prediction methods.

Another aim was to produce something that was new to the web and different from the normal prediction packages.

With the assistance of programmer James A. Watson, HZ1JW the first phase of the project was achieved.

He produced a very readable and easy-to-understand interface.

Mark Lawrence, G0WMT volunteered to step in and has completed a sophisticated yet easy to use, set of point-to-point predictions.

User information

The landing page shows a world map with signal to noise ratio (SNR) coverage from the UK for a given HF band at a given time.

Reliability and S-Meter output is available simply by choosing the desired element from the drop-down box.

There are drop-down boxes for the time and frequency, the starting prediction time will always be the current hour and the frequency will be 14.0MHz.

You can then easily select a different band or time.

Point-to-point (P2P) predictions are available from the menu at the top of the page.

Filling out the form and clicking the Create Prediction button will start the process—a choice of output is available from the menu.

New innovative features have been used to display the prediction engine output—e.g. hovering the mouse in the plot area shows static data for a particular hour.

A distinct feature is the ability to change the colour scheme on the output plots; this was provided to cater for a user with a particular preference or need.

While the tool is thought to be intuitive, explanations are available on the Usage Tips page.

Also available, under Credits, is information for those studying propagation.
