The poorly designed unit Joe's talking about is the SignaLink. It's 
mono, it's a pretty old design, and it's got a Pin One Problem.

I recommend several good quality USB audio interfaces made for semi-pro 
audio or for computer gaming. I'm using a 5-year old Tascam that's long 
discontinued. I paid about $75 for it when it was still a current 
product. A few years ago, I noticed that N8LP has been recommending the 
ASUS U5 and U7 interfaces. I bought a U5 and borrowed a U7 from neighbor 
N6NUL. I fired up both in my contest station for evaluation. They are 
real winners -- great performers and a real bargain. You may need to get 
out your soldering iron to make suitably wired connectors to interface 
with your radio.
