Get a softrock 40. I/Q sampler based on the quadrature
sampling detector (fully balanced. Virtual ground, thus not Tayloe). High
performance, good sensitivity. Yields I/Q in stereo audio for baseband
processing. If you already have a USRP, get the LFRX.

GUI shown in the second link (PowerSDR).

You could try tapping the IF out of an old radio (which uses FETs) . But you
will need a mixer and band pass filters to bring the signal down to a
range which your soundcard can handle.
