Caution the audio is a bit loud...still need to install my video editing software. I just finished the receive section, still need to build the transmit section. Once I get the transmit section completed I will upload another video...don't worry it will have better audio/video.
Check out http://kb9yig.com/ to buy this type of kit,
http://www.wb5rvz.com/sdr/ensemble/ for building instruction.
