Wednesday, I got all the parts together and hooked them up to test the bits worked together. I plugged in some whip antenna lying around at the radio club rooms.

I made a quick GNURadio app to show an 8MHz bandwidth waterfall and a slider for the frequency, so I could move the slider and watch the noise attenuate as it scrolled through frequencies the antenna wasn't tuned for. Next step is to automate that process and produce a nice plot of the results.
