In short, the author uses a TV capture card with a Conexant Fusion 878A chip as a fast Analog to Digital Converter (16-bit / 896kHz!). Then he _directly_ connects an antenna to the input - see the result at http://www.domenech.org/homebrew-sdr/spectrogram-lf.htm . Not everything is translated to English, anyway - have fun. I'd love to experiment with this but... unfortunately my TV card uses some other chip, so I am now starting to look for some bargain at on-line auctions hi 73! Marek SQ5BPM
