  • Home Brew Bug Detection Better Than TSCM

    From warmfuzzy@700:100/33 to All on Tue Jun 14 17:00:17 2022
    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.

    Never stop imagining.

    Peace.

    Often cheaper is better.
    One thing I've found to be quite useful over the years is a small AM radio. I have been using them for checking for RF interference for decades. I use one all the time for checking the horizontal oscillator on CRT Televisions, diagnosing pulse power supplies. As a TSCM device it would be useless for wired analog bugs but for modern digital devices it could be a cheap and effective tool. Try holding it near any digital device and interference will be easily received anywhere from a few inches away to several feet.

    ... I'm not a procrastinator, I'm just waiting for the right moment
