Hi all,
Thanks for the responses, so far.
Yesterday I came across the elektor project on SDR via USB and soundcard, at -
http://www.elektor.com/magazines/2007/may/software-defined-radio.91527.lynkx
. All the details including the necessary software is freely downloadable, from
the Elektor website.
This seems to be fully functional in 150 kHz - 30 MHz band, and needs a
supported sound card, for its operation. Pre-assembled boards costs about 110
euros (tested units from Elektor), where as one can consider building the unit
on his own tor educe the costs. Pre-fabricated PCBs for this project is
available for 28 euros or so per piece.
Can someone comment, whether it is possible to make the unit working with GNU
radio? If the answer is yes, how to proceed? What would be the first steps?
Thanking you,
Mathew George

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.

Frank Brickle and I wrote the SDR core for the software in the
GUI shown in the second link (PowerSDR).

Hi,
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.
