Anybody speaking russian?

Post by JEL » Tue May 01, 2018 6:56 pm

I just recorded this a few hours ago... it's somebody speaking Russian...

I think it may be some kind of maritime talk, as the frequency-plan I have says this frequency is allocated to maritime use.

It's 5106 kHz, USB (It appears to be about 1000 Hz wider than normal USB band-width though)

I edited out the 'silent' parts, and kept the parts where there is speech.
The thing is, the 'silent' parts weren't silent, but had some type of carrier-wave going on.
It's nothing I recognize.

So if anybody understands Russian and can translate what is said, it would be interesting to learn what this is :)

It's outside of the amature HAM-bands, but I don't know if Russia has a different band-allocation. It doesn't sound like a regular Russian HAM-operator though (I get quite a few of those on the normal HAM-bands, and generally they don't sound like this)

To me it sounds like 'typical' maritime material (Based on what I hear on the VHF maritime band)

The video is 7 minutes long, and recorded using SDR#.

EDIT: Just wanted to add this: At the end of the video the carrier just gets cut off. After that there's just static.

They came back... Same frequency, same modulation.
I still don't know what this is though.

But here's a second video with even more things going on.

A few points of interest in this video:

One station making calls for the first 2½ minutes.
He appears to get no reply.

At 5 minutes 15: A Rapid swooping sound on top of a station's talk.
I don't know if it is 2 signals on top of each other or what is happening.

At 6 minutes: A single digital ping.

At 8 minutes and onwards: Some talk between stations. One station sounds like it's broadcasting with a heavy feedback-loop.

The video here is 12 minutes taken from a 1 hour recording, where I cut out the pieces without talk.
There is a constant carrier-signal (The noise you hear between talking stations) which gets cut off at the very end (Not part of this video)
When the carrier is cut off, nothing else happens. Perhaps it's some kind of relay, like a repeater-station. I don't know.

Just a quick update, if anybody is still curious.

I got this message, from the web-site: https://www.numbers-stations.com, about the videos:
Two callsigns; Luchnik sends Vestnik coded message and its repeated because of bad reception. Military communications.
