    Hello guys!

    I was just wondering, what is the easiest way to scan for a RF or an
    ultrasonic bug? To buy a receiver and scan around the suspected object
    ? Is that theory correct?

    I believe it is "Opto-electronics" who produces a Freq counter which is
    designed for such a thing. Do a Google Search for "electronic bugs".

    ** For RF bugs you need either a special " bug sweep detector " or else a
    wider range spectrum display device.

    Ultrasonic ones would require a special acoustic receiving device.

    Bugs that only transmit on command at random & brief intervals are near
    impossible to find by electronic means.

    The KGB had a mole at the construction site of the US embassy in Moscow
    and they filled the concrete beams with little capsules that formed
    resonant cavities. When the spooks outside beamed some microwaves at
    the building, talking in the room modulated the resonance enough to
    detect with an off site receiver. Playing pinknoise or punkrock at
    levels louder than the conversation were needed to mask this.

  5. Punk rock? Do you have any idea when that embasy was built?

    Service to my country? Been there, Done that, and I've got my DD214 to
    prove it.

  6. Apparently the seventies, and they started finding the bugs in the
    eighties. It was so riddled with bugs that they had to abandon
    the building, and bring in US people to construct a new one.

    The "cavity" bit threw me off a bit, because a quick reading made
    me think he was talking about an earlier bugging incident.

    The book I have about "electronic eavesdropping", which seemed to
    be quite the standard at the time (though maybe simply because there
    weren't really books on the topic), has a bit about that embassy thing,
    and the book is now about forty years old.

    It dated from the forties, it was a specific thing, "The Great Seal of
    the US" that the Russians gave to the US ambassador that was set up to
    be a modulator of an outside radio signal. That was a pretty legendary
    thing, though certainly there was no punk music at the time to mask things.

    I'm not sure the later embassy used anything but traditional active
