Yes, because you can't adjust the filtering bandwidth, so there's only one sensitivity here. Of course, the smaller you make your bandwidth, the lower the amount of noise is you receive, and the less signal power you ...

There are at least a couple differences that aren't just based on the specs (wattage, etc.) of current commercial offerings known to the OP. One advantage of SDRs is that some SDR setups (Hermes Lite 2, et.al.) allow not only monitoring the final RF output, but also allow the use of computer/DSP pre-distortion to help clean up the signal all the way from or ...
