[Elecraft] Performance of internal USB sound system compared to external one?

[Ken Arck]

Admittedly, I am a new owner of the K3s and am still learning my way 
around it. I bought it mainly for use an IF radio for my DEMI 2 mtr 
xvtr, which I use for EME work. It came highly recommended as one. 
Prior to the K3s, my EME workhorse radio was a Kenwood TS2K which 
actually worked "fine" but as most are. I am always looking to 
improve my station. I used a RigBlaster as the sound card interface 
with the computer used.

I am using the USB port for everything - audio in/out, PTT, CAT 
control, etc. along with some VSP software. I also run a splitter on 
the RX line from the EME array with one side going to the DEMI xvtr 
and the other to a FuncubePro+ dongle. The K3s feeds WJST and the 
FCD+ feed MAP65, running side-by-side.

Trying NOT to drag this out too much longer, it seems to me the 
K3s/DEMI setup simply doesn't decode as well as the TS2K did (does?) 
and I'm wondering if anyone has real world experience in comparing 
how well the USB audio method versus the IN/OUT and the Rigblaster 
interface to the computer's soundcard. The FCD+ decodes MUCH better 
than the K3s/DEMI setup as I currently have it whereas the TS2K 
seemed to be better on the weaker signals.

Maybe I just don't have something setup correctly.....

TIA

Ken
