dl-fldigi is an adapted version of the excellent free FLdigi soundcard decoding software. It takes the audio from your radio, decodes the balloon's signal, and then sends the telemetry it's found over the internet to a server running habitat, which plots the payloads position on to the SpaceNear map.
First grab the latest version on the projects page: dl-fldigi
This new version parses the data it receives and splits it up into the boxes and calculates the distance and bearing that the payload is from your base station (based on the latitude and longitude you previously input). You may need to resize the window width when you first open dl-fldigi to fit your screen.
First thing is to enter your location (this is required to appear on the map and to calculate distance, elevation and bearing (Please remember to put in your latitude and longitude in decimal format using + or - rather than NSEW e.g. 52.0000 -0.12345 You will also need to put in your altitude, you can put in 0 if you don't know this)
