And what we didn't realize, though, is a feature of electronic helicopters, which is great when you're flying. If you lose radio signal , it'll go full speed to stay in the air. I think you guys understand where I'm going with this.
Not with enough timing resolution to compare one receiver to another, to see which one was hit first, or how the interference moved across the network. What they needed was the raw radio signal itself. So, they started designing specialized receivers that could capture the data in much higher temporal resolution.
So whenever the Soviets wanted to listen to a conversation, they blasted radio waves from outside, likely from a van or a nearby building. And then they received the radio wave they got back from the bug and extracted the sound information modulating that radio signal . The Americans nicknamed the bug "The Thing," since at first, they didn't know how it worked.
to solve these problems-- and also giving them what they call psychological safety, a culture where nobody's laughed at, where you're given space to propose something unreasonable, And they hacked together a radio signal jammer with some soldiers.
there would be a collar put on the snow leopard individual. And then we'd use radio signal to see where the snow leopard went. But you can imagine, there's mountains.
- Here's the experiment. We've got a power source sending a radio signal down a transmission line to an antenna array, and we put it in an anechoic chamber to reduce interference. We've got a receiving antenna at the other end, which is able to pick up the signal and tell us just how much power is actually making it
But despite multiple sweeps of the building, the Americans couldn't find any hidden listening devices. Then in 1952, they detected a radio signal coming from the ambassador's office. - They said, "It's coming from over there behind that plaque on the wall." And they took the plaque down and put it down somewhere,
And your internet still works in your little cottage and you can make a donation. You're going to save someone who's drowning and then you get a radio signal that says, wait, there are these people who are drowning
He had beautiful raw data from two different stations. - At last, they had what they'd been missing, the raw radio signal itself. Samples of the raw voltage off the antenna capturing the actual digitized radio waves millions of times per second from two stations,
and that's how to reset the age of our bodies. And what you can see here in his diagram from 1948 is that if you lose a message, a signal, a radio signal , or, say, a Morse code signal between the sender, which he calls the "transmitter," and the receiver, if you lose some of that information,
