This site would not be available but for the kind co-operation of the ITU through the guise of Chris Behm, the compiler of ITURHFProp. The program calculates the HF path parameters in accordance with ITU Recommendation ITU-R P.533-13. Predicted sunspot numbers used on this site are gathered from NOAA NWPC.

Thanks are due to James Watson, HZ1JW whose hard work developed the Area Coverage page.

The Point-to-Point page and workings were developed by Mark Lawrence, M0WMT. His knowledge and creativity; designed, developed and wrote the code for this page.
