The Sample Type used by the EMU card is ASIOSTInt24LSB, so you have to reformat it, e.g. by calling the routine int24to32inPlace of the Steinberg ASIO SDK. I made the same mistake initially :-) 73 Alberto I2PHD ___ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://www.mail-archive.com/flexradio%40flex-radio.biz/ FlexRadio Homepage: http://www.flex-radio.com
Re: [Flexradio] Best Sound Card For Sensitivity Only
Thanks for all the suggestions, in this case I am not looking to use it with PowerSDR, it is for another project with a Winradio G305. I am looking to try and improve the VHF/UHF sensitivity, I currently own a Firebox, FA-66 and Delta 44 which I use with the SDR1000. In your expert opinion Alberto, would I get as much as 3dB sensitivity improvement over these other high end sound cards, if not I probably could not justify buying it.

In your expert opinion Alberto, would I get as much as 3dB sensitivity improvement over these other high end sound cards, if not I probably could not justify buying it. Are you looking for raw sensitivity (which would seem to equate to gain and noise figure) or dynamic range? if it's just minimum detectable signal that you're worried about, why not a very low noise opamp. There's a fair number of low noise op amps, and if you're really obsessive about 1/f noise, there are some very, very quiet JFETs out there, but more likely, things like construction practices (the kind of resistor you use, and whether you use a board or floating in air on teflon post construction.

Re: [Flexradio] Best Sound Card For Sensitivity Only
Andy, at one time Bob N4HY was experimenting with the Lynx series http://www.ramelectronics.net/html/sound_cards.html#lynx and http://www.ramelectronics.net/html/lynxtwo.htm but you should note that drivers aren't available for all the operating systems and the Lynx card has not been incorporated as a supported card for the Flex-Radio SDR-1000 PowerSDR console. Have you looked at the HPSDR Janus board? the A/D chips in that board might offer just about the highest performance available at a reasonable price http://hpsdr.org/janus.html de ken n9vv Andy Smith wrote: Hi Folks, Can someone please tell me which soundcard specs to look at that will give the ultimate in SDR sensitivity (not just for the SDR1000), I presume the number of bits and dynamic range make a difference but I am looking for the ultimate (ideally USB or Firewire) sound card for sensitivity only, can the FA-66 be bettered for sensitivity alone?
