[hpsdr] Silicon Labs chips

[Lester Veenstra]

The phase noise/frequency wander was with the AM/SW broadcast version


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.
