[Elecraft] USB sound dongle

[Barry LaZar]

Tony,
     You are correct. I do use 2 cards. My "good one", EMU-0202, takes 
the I & Q data from the KX3 and gives me demoded audio which is piped 
into a follow on digital program  using VAC. My laptop's sound card 
takes the audio from VAC for use with my digital software It just never 
occurred to me to try anything else. I use FLDIGI and MixW as the follow 
on software. I like both.

     BTW: The KX3 manual implies that going to 192KHz is not the best 
idea as there is fall off in response that far out. It's hardly 
noticeable at 48KHz, so I use that. As I am tuning the KX3 in sync with 
what I do on the screen, It hasn't been a problem for me.  I can change 
the sampling rate to greater than 48KHz if I want. I just don't.

     After you get it all sorted out, it should knock your socks off. 
It's been the most fun that I've had in a while.

73,
Barry
