[Discuss-gnuradio] More sensitivity testing on Basic_RX/USRP2 combo

[Marcus D. Leech]

I was able to produce a -98dBm signal today, and in a 5KHz bandwidth,
that signal produces a roughly 7dB increase in detector output
  level, compared to nothing plugged in to the Basic_RX.  So, the MDS,
is somewhere probably around -102dBm.  Some of the best
  HF receivers around can perform well at around -130dBm input signal,
so -102dBm isn't that terribly bad considering there's
  no gain in front of the ADC.
