[Elecraft] SDR_Sound_Cards

[KQ8M]

Bill,

Thank you for relaying that for the rest of us. I guess I am one of those Larry was referring to.

Larry,

Thank you for doing the extra work amidst my insistence the card was crap. I will give your instructions a try and connect one up to
my Win 7 machine again. I have never used the 0204 to listen from. It has only been used for the input from the SDR/LPan. I will
give it another shot nevertheless.

The best thing about Win 7 is having the ability to set the cards parameters from within the sound applet through the Control Panel.
Unfortunately there is no such thing in XP.

Thanks to N8LP for the info he posted below. One happy discovery that might help eliminate some E-MU 0204 USB soundcard driver angst
for Win 7 64 bit users: Windows 7 64 bit has an E-MU driver resident in the operating system. This driver will *not* automatically
install when the 0204 card is first plugged in, but is easily installed from Device Manager via the Update Driver utility. Win 7
will find the driver and install the 0204 card in about 5 seconds. The driver does not seem to have a graphical user interface, but
works fine on my system with NaP3 for sampling rates up to 192K. This driver is dated 11-12-2010 and is version 6.6.1.1 by Creative
Labs. Follow Larry's instructions for defaulting the sample rate to 192 K in Windows mixer setup and set the output to something
other than the EMU 0204 in NaP3 setup and it should work well.

---------------------------------- 

FYI to all reading this thread: The 4GB RAM issue only appears to affect 
playback. The problem is that the audio will break up/lose sync after a 
period of time. This only applies, of course, if you actually listen to the 
output of the SDR. 

If you select another sound card in the Output selection in NaP3, it will be 
fine. You really don't need 192kHz for playback, since the widest filter is 
10kHz. So any sound card will do just fine, including a built in one. You 
can still select the E-MU for Input and use 192kHz sampling for input. 
Therefore, you don't need to give up your extra RAM. 

I have updated my system requirements page with this info...
