Sitting around listening to static from T'storms to the southeast, I grabbed this screencap off SDR-Radio, and I thought I'd share it:http://i1049.photobucket.com/albums/s387/jFarley44/StormNoise15Mar12.png
This cap reflects the console state immediately after a distant lightning strike. Here, the FFT display has just jumped up about 10dB from its normal position. What's pretty cool about this is the fact that because I do most of my DXing with a small resonant loop, the response of the loop is clearly seen as a crown in the noise floor. Likewise, the horizontal lines in the waterfall pane corresponding to strike noise brighten around the antenna resonant point.
