Some experimental code to drive an RFM01 RF receiver from a Raspberry Pi to read transmissions from a Fine Offset WH1080 weather station.
There's more information on this at www.susa.net/wordpress, and the links on that page (some in the comments section) direct you to forum threads that further discuss the subject.
Don't expect this to be a stable or reliable setup. It may be, but there are environmental factors that can prevent you from getting a consistently clear RF signal, and there can be problems getting a consistently stable Raspberry Pi!
