How radio waves propagate in other than straight-line paths is a. Obviously this does not happen all the time, because long distance communication depends on radio waves traveling beyond the horizon. HRD DM-780 () DXLab WinWarbler RTTY and PSK31. ARRL: Radio waves, like light waves and all other forms of electromagnetic radiation, normally travel in straight lines.

A rudimentary knowledge of sunspots, solar flares and mass ejections will help the amateur take advantage of these effects to enhance his pleasure, or understand his plight.īelow is an active update from Paul Herrman’s site of the current band conditions. fldigi A digital mode program for PSK31, RTTY, and many other operating modes. The Sun, being the largest engine in our solar system, has a great effect on propagation as its “exhaust” interacts with our Earth’s magnetic field. The package includes ICEPAC, VOACAP, and REC533. Department of Commerce NTIA/ITS Institute for Telecommunication Sciences High Frequency Propagation Models. It is a Linux X Window Amateur Station Tracking and Information Reporting application.

If you’re looking for the ARRL Propagation Charts, you’ll find them by clicking here. Propagation Software Ham CAP 1.5 HF propagation prediction tool for Amateur Radio. The APRS Amateur Radio software of choice on Linux is called Xastir. More detailed discussions and the underlying mathematics of radio propagation physics can be found in the references listed under additional resources. 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. Results are rendered in an easy-to-understand colour-graphic display. How radio waves propagate in other than straight-line paths is a complicated subject, but one that need not be a mystery. Propview PropView uses the IonCAP propagation prediction engine to forecast the minimum and maximum useable frequencies between two locations over a specified 24 hour period.
Obviously this does not happen all the time, because long – distance communication depends on radio waves traveling beyond the horizon. ARRL: Radio waves, like light waves and all other forms of electromagnetic radiation, normally travel in straight lines.
