[Elecraft] SDR_Sound_Cards

Thu Sep 13 14:19:05 EDT 2012

Olli,
     I'm sorry to read your comments. I'm running NaP3 with a E-MU-0202 
sound card and the beta driver, the same driver you use. My PC is a 
Toshiba laptop and the OS is Win7 Pro64. I must admit it took a little 
fiddling to become stable, but it does work. The only problem that still 
remains is when I do a lot of fast tuning of my KX3 using NaP3, the 
system becomes unstable and crashes, but otherwise, it works FB.

     I should also tell you that I have VAC installed and am using 
FLDIGI for PSK31. I use  my laptop's sound card for that step. This 
combination seems quite stable, so far. So, don't give up yet. Have a 
cold beer and start again:-)

73,
Barry
