Thanks John and Matt for your answers. Indeed Matt, in my band of interest there is DTV signals since I'm trying to record them !! :). Unfortunately, i can't put the enclosure because the SMA connector is to big to close the box. Indeed the MCX to SMA bulkhead connector wasn't in my package (there was the SMA to SMA instead - it's normal Matt ?) and so i'm using a MCX to SMA adaptator.
You should have gotten an MCX to SMA cable. Send me your shipping info privately and we'll get you one.
I have put some screenshots on my Picasa Album Web (i have put a 50 ohm terminator but not the enclosure): http://picasaweb.google.fr/damien.serant/USRP2WBXScreenshots?authkey=Gv1sRgCOPtyo2jg-6Nfw&feat=directlink
Your gain of 0 is unusably low. Set it to at least 20 or 25. Also, you're going to see harmonics of the motherboard clock at multiples of 100 MHz, but they will be smaller relative to your incoming signals once you turn up the gain.
The next step it to put in a signal with a known amplitude to calibrate the undesired signals against.
