I just heard about something that I thought would be a good addition to this echomail network. Its about non-typical TSCM fox hunting, or TSCM bug detection. You may not have been aware but electromagnetic radiation sources produce harmonics in the ultra-sound spectrum above the spectrum of audio
that humans can naturally hear on their own. This works for radiating EM signals of most if not all types. Just go into a suspected surveilled area
and bring along an ultra-sound receiver and you will actually pick up scatter from the EM emissions leaking into the sonic frequencies, specifically ultra-sonic. So when Joe Blow the neighborhood spook tot spends 20K $ on
some sweet kit you can get shizz and giggles that you could detect the emissions yourself for a couple hundred.
