[hpsdr] Include VNA capability in the Pheonix?

[Rob Frohne]

Hi Everyone,

It seems to me that we can include without much overhead at all vector 
network analyzer capabilities in the Pheonix board.  While there are 
other stand alone VNA options available (N2PK and IW3HEV), I think the 
large dynamic range, and other good specs of the Pheonix will yield a 
better VNA than those options.  The block diagram for a narrow band VNA 
that fits our architecture is shown in a sketch I put on the web at:

Have a look at it, and share your thoughts with us!

Tnx & 73,

Rob, KL7NA
