Yes, I would imagine that -70dBm would be within the range of detectable
signals of the "Naked" ADC (buffered by LFRX).
The "reference" power level of the ADC on the N210 is somewhere around
+7dBm (from memory), and it has 14 bits resolution, so roughly 84dB of
dynamic range, which definitely puts you in a region where -70dBm
shouldn't be a problem.
