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

[Philip Covington]

I am not sure that the cost would be lower than Mercury.  You still
need all the support for an ADC, plus you need the front end mixers,
PLL, blah blah blah...  By the time you add the cost up you could have
paid for the 100 MSPS+ ADC.
