Basically you can use a regular USB DVB-T dongle, the ones you use to receive TV, as a software defined radio, a.k.a, frequency scanner. Well, kind of.
The concept in itself is pretty cool, so I decided to grab one of those and start to play around. You can do lots and lots of stuff with these, but I always wanted to see if I could pick some satellite transmissions.
You know, the crazy guy in a barn picking up radio signals from outer space, listening to ET phone home. So after some work compiling and hacking code I came up with my desktop having:
- GNOME predict, awesome app for satellite tracking.
- gqrx, IMHO the best app to monitor the æther, connected to wxtoimg
- wxtoimg, to decode NOAA satellite info
- an homemade dipole antenna
NOAA 19 Weather Satellite data as it passed over Europe, filtered with wxtoimg.
