Welcome to APRS VHF TROPO detector.

This project uses APRS-IS stream to filter RF->APRS-IS stations and checks
which distance each packet traveled. There is special configuration for high altitude
stations, typically installed on mountains. Information is then sent in real time to
dedicated Telegram(tm) channels.
