Spectrograph of the broadcast radio spectrum imaged with an RFSPACE NetSDR software defined radio. The radio digitizes the whole 0-35 MHz spectrum, tunes to the 0-1.8 Khz band and performs a 65536 point FFT. The resulting resolution is 31 Hz per pixel. Each pixel is colored using a palette based on their signal strength. In this case, red and white are the strongest signals while black are the weakest. The X-axis is frequency starting at 0 Hz and ending at 1.8 MHz. The Y-axis is time with an approximate resolution of 100ms. In other words, every pixel captures radio waves in time and is 31 Hz wide and 100ms in height.

Nice Pic and very interesting!

This is very interesting and beautiful too. I wish I knew more about how this was made. Is this a recording through time of each frequency? Red means greater energy? This is also very neat to look at in a virtual reality viewer, such as this www.3dpan.org/77552
