Radio astronomy with RTL-SDR and RasbPi

This looks like an interesting project. Might have to experiment with this a little. I’ve been kicking around some ideas about a homebrew radio telescope – basically a ~1400MHz 15-20 element yagi, fed into an SDR dongle through a couple of LNA’s and a bandpass filter.

More info on UHF homebrew filters etc. can be found on Paul Wade W1GHZ’s site, also good info from the British Astronomical Association, and

I’ll post any developments I make on here, and on the projects page on my main site.
