Direction finding

But the most rigorous independent researcher on this, Noam Nachman Tepper, went through the Syrian interrogation records and the testimony of the officer who actually broke down the door, and his conclusion is that there's very little chance the Syrians ever located the signal.

So before we even get to the physics of direction finding, we're dealing with two mutually exclusive stories about whether direction finding happened at all.

Right.

And that's what makes it a teaching case.

You don't need to monitor twenty-four hours.

You set your receivers up at eight twenty-five, and you wait.

And if you've got direction finding equipment, you take a bearing the moment he keys up.

And the bearing tells you what exactly?

Absolutely, it was.

I mean, technically, it was called, by the British, it was called RDF, Radio Detection Finding.

the word radar hadn't yet sort of come into being.

And in fact, I've got a feeling, I don't know, you'd probably be able to tell me, I've got a feeling that radar was actually an American word that was then applied to the whole technology.
