[Elecraft] K3 panadapter choices

[Jim Campbell]

Erik,

Most laptop built-in sound cards won't work for SDR because they only 
have mono (microphone) input.  SDR requires a stereo (line) input.

That said, I have found that a USB sound dongle such  as the 
SoundBlaster Live! 24 USB or the Sound Blaster X-Fi Extreme USB work 
just fine with my laptop.
