Decoding RDS in GNU Radio with the RTL-SDR

DangerousPrototypes.com have brought to attention a GNU Radio RDS decoding project from the website at Anotherurl. Check out the original post here.

Anotherurl uses a GNU Radio Companion flowgraph and a .NET program to decode FM RDS messages. RDS is an acronym for Radio Data System, which is used in FM radio transmissions to embed information such as radio station and programme/song information. Some conventional FM radios display this information on an LCD screen.

The popular SDRSharp SDR receiver also has RDS decoding built into it’s FM receiver already, but a GNU Radio implementation is very useful for learning how RDS works.
