[hpsdr] HPSDR Performance Test

[Helmut, DC6NY]

Hi guys,

Adam, VA7OJ/AB4OJ, published the results of his thorough and competent
performance test of an ANAN100D on his webpage
http://www.ab4oj.com/sdr/apache/anan100d_notes.pdf

As we all know, that this complete radio is based identically even in
details on the HPSDR development, this test should be also valid for
individual setups.
The HPSDR group can be really proud of this superb design, which would push
the radio with distance on the top of Rob Sherwood's list, hi. A narrow
spaced DR3 of 112 dB is a dream.

Thanks to all voluntary hardware- and soft-developers. Let's continue.

73, Helmut, DC6NY
