As those of us who have used the USB dongles that were mentioned in QST will 
tell you, the SSB phase noise is not nearly the issue that folks make it out to 
be.

The *biggest* problem with anything Silicon Labs is finding someone to sell you 
any.  Silicon Labs (and my former employer Conexant, now Entropic) just do not 
want to talk to you unless you are going to buy a few hundred thousand ICs.

As with the USB dongles, if you can find another radio that uses the chip, you 
might be able to experiment with them.  If you haven't checked out the USB 
dongles yet, it is well worth the time.  You can't beat a receiver that costs 
$17.
