I wasn't able to change the VAC sample rate to 48K either. Trying to force it by changing the VAC range from 11025..96000 to 48000..48000 just gave me "unanticipated host error" when starting PowerSDR. As you say, dropping PowerSDR's rate to 44100 to match VAC eliminates the spur. Evidently the sample rate conversion between VAC and PowerSDR creates the spur. Here's a PowerSDR spectrum showing the spur: http://i187.photobucket.com/albums/x269/jmknapp/psdrspec.png Using Audacity to sample what's coming off the VAC "cable" going into PowerSDR shows no spur (in the pass band anyway): http://i187.photobucket.com/albums/x269/jmknapp/audspec.png Joe _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flex-radio.com/ Homepage: http://www.flex-radio.com/
