An introduction to the new Propagation Studies Committee propagation predictions tool
RadCom readers may be aware of RSGB’s new HF propagation prediction project, software and website.
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 we are well on our way to achieving our aims.
Jim has a full-time job and has so far managed to program a very readable and easy-to-understand user interface.
Clicking on the button below will launch the test page for the project.
User information
It should be understood that this software is still under development and the page will change without warning.
At this stage of development only cosmetic changes are now envisaged.
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.
It is also possible to depict Reliability and S-Meter output 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 3.5MHz.
You can then easily select a different band or time.
Also on the page are further hints on utilising the tool.
A relatively new feature can also be accessed from the bottom of the area coverage page.
This is the Point-to-Point (P2P) prediction site, codenamed “Proppy” that will be migrated to this page.
The page is simple to use and users should find it intuitive.
Simply drag the pointers to the two points on the Earth that you want to check, fill out the forms and click Run Prediction.
