HFBeacon is a simple application which informs the user which HF propagation beacon is transmitting at the present time.
This app is for ham radio operators, shortwave listeners, and others who need to know the propagation conditions across the HF bands. Please send comments and suggestions to mathuin@gmail.com -- thanks!
