Unfortunately, no. One of the first things I tried. Also, most internal 
sound cards have a mic preamp that can be turned off.

If it's Field Day, I assume you're using RTTY or trying for satellite 
QSOs. The internal sound cards can be sort of OK for most RTTY signals, 
but the outboard adapter will help for the weak ones. And for other 
digital modes, I would REALLY want the outboard interface.
