[hpsdr] Built in Antenna Tuner

[wully]

Hi Bhanu, All

I agree completely. I am using a computer controllable antenna coupler 
with bistable relays to switch the coils and the condensors. When I tune 
the frequency of my HPSDR system, I can push a button on the PC screen, 
and the coupler will use the nearest tuning frequency it has in a list.

There are so many different antennas and tuning possibilities, that I 
don't see a a fully integrated solution, which would be ok for all 
amateurs.

I am very happy with the HPSDR project as it is now. Let us concentrate 
on the points which are really special: direct conversion, diversity rx, 
FPGA-work, Class-E-TX etc. (And not to forget Hermes as a VNA!! Thanks 
Phil!).
