There is an invisible layer to the war in Ukraine.

vital to every aspect of decision making in warfare.

And hidden in the radio noise are signals.

We're going to look at three aspects of radio

in Ukraine, the interception of communications

to combat censorship online, and the mysterious silence

of a number station known as the Russian Lady.

This, as far as we can tell, is a recording

of a Russian soldier in Ukraine, but the people who captured it

were far away and weren't using radio equipment directly.

A software-defined radio is a computer with a radio receiver

across a wide range of frequencies at the same time.

So you can watch a waterfall of radio signals

one you're interested in, then choose exactly how you want

to decode the signal just with the click of a button,

Connect it to the internet and, suddenly,

can stream any radio signal your antenna can pick up.

And many people are very interested in monitoring them.

Couple those web servers with a chat room app like Discord,

and you can create an open-source intelligence

team of volunteers, which is what Boyan Malashev did.

Well, Ukrainian Radio Watchers is a really brilliant community

who give a lot of their time and their efforts

in trying to listen the Russian communications.

We were shared in platforms like Reddit and Twitter,

about us, started to join because most of them

wanted to get translations about what is happening.

And we had pretty active translators doing this.

I think in the server we have 100 translators.

Sometimes, I listen, and sometimes I record.

and how I help the server is by developing the Discord server

The recordings and the main function of the community,

I do not know anything about radios and communications,

but it's important because we are dealing with war crimes;

We heard how commanders and officers are arranging

We are trying to find the call signs of them.

The question of whether we can trust the recordings

This is obviously still a conflict, and what we do know

is that Ukrainians themselves have been exceptionally good

in terms of their communications about how successful they've

That said, there, I think, is very little doubt

that some of these communications are genuine.

Some of the content would be exceptionally hard to fake.

And when you put together all of the other material

on social media of captured Russian troops,

pictures of the radio equipment they were using, all of that

together paints a picture that would be very hard to fake.

When you hear the conversations, you can feel it first,

and then you have-- we have the experts who can check

And as we're monitoring a whole day of conversations,

it's not fake because sometimes something is happening

And in the next seconds, attack actually happens.

We could see that the airstrikes actually happened.

So yes, we have some evidence that the conversations

Both sides are fighting quite an aggressive information

campaign, so you do have to be wary of that within analysis.

Do the things that we're hearing in these transmissions marry up

Do they compare well with what other sources are reporting?

So if we have seen that there are Russian soldiers carrying

unencrypted radios or notionally unencrypted radios, and now

that have been intercepted, that all points
