[hpsdr] New entry in the (almost) SDR arena

[Philip Covington]

Hmmm...there is nothing special about this...nothing that isn't
already done in the USRP, SDR-14, and SDR-IQ and the soon to be HPSDR
Mercury.  It appears they are just digitizing the 10.7 MHz IF - I and
Q comes from mixing the complex NCO with the real signal samples from
the ADC.
