Living Sonagram: A revolutionary tool for Monitoring


Monitoring of wide frequency ranges can be an art. And hard work, too. The technique ot the “Living Sonagram” makes this task easy:

  • record a frequency range of up to 10 MHz, for e.g. 24 hours or less or more
  • define a range of time ad frequency you want to analyze offline
  • build up the “Living Sonagram”
  • tune. demodulate, and decode in this whole range just with your mouse (see screenshot on top)

You must see this to believe it!

The Software has been developed by Simon Brown.

I wrote this paper as a step-by-step introduction into this technique.
