This map shows real-time radio propagation from stations operated near 144 MHz. It uses data gathered by Automatic Packet Reporting System-Internet Service (APRS-IS) from packet stations in the amateur radio service. The map shows activity from the past hour.
The VHF Propagation Path Profiler presented here is a comprehensive application that allows us to graphically render and mathematically compute various relevant VHF/UHF propagation metrics including VHF propagation path losses, over the realistic terrain profile between any two point-to-point locations on the surface of the earth.
Nautel has partnered with RF engineer Roger Coudé, the author of “Radio Mobile” [1] to provide simple, fast online VHF/UHF coverage mapping and point to point analysis worldwide. These tools are part of the new Nautel RF Toolkit, available free online at the website www.nautel.com.
HF Propagation Map. HF Propagation Map. This mapshows real-time radio propagation from stations operating on 11 bands between 1.8 and 54 MHz in theamateur radio service. The display shows worldwide activity from the last 15 minutes and is automatically updated about every minute. JavaScript must be enabled to use see the real-time graphics.

QRadioPredict is an experimental software for VHF-UHF propagation prediction and radio coverage analysis. Currently it works on Linux and has been ported to Windows 32 bit (Vista) and has the following features: Elevation profiles are taken from NASA 1 degree SRTM 3 arcsec elevation files (*.hgt) obtainable from various sources.
