I don't think that it is quite off topic but is certainly very impressive, somethink to look into & I beleive will be of interest to some of us on here. Unfortunately the language is a problem for me so really the spectogram site was the one that I understood. Regards Gary - G4WGT. -----Original Message----- From: owner-rsgb_lf_group@blacksheep.org [mailto:owner-rsgb_lf_group@blacksheep.org]On Behalf Of Marek SQ5BPM Sent: 24 August 2004 16:24 To: rsgb_lf_group@blacksheep.org Subject: LF: Slightly off-topic: 878a as an 896kHz ADC for a software defined radio Hi all, Maybe someone's interested, I just found this experiment at http://www.domenech.org/ . 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!
