Other Beacon Monitoring web pages are linked from the International Beacon Project Monitors site. This monitoring site is strongly inspired by Faros the great software which was written by Alex Shovkoplyas, VE3NEA and also using the original representation by Peter Ralph Jennings, VE3SUN. Thank you very much.
