UVB-76 Live stream

Ukraine - 34 Kanal



During almost 12 years the repeater has been up, I have been keeping it apolitical. But Putin has gone batshit and UVB-76 radio station is a weapon. So, while I keep translating it, you are welcome to also watch the Ukrainian news channel '34 Kanal' to see, what kind of events this signal is actually participating at today.
Slava Ukraini!

DISCLAIMER: I have no association with UVB-76 station, neither do I have any clue what is the content I am relaying. I can only assure, that the signal is received on 4.625MHz about 300km NW from supposed origin and retransmitted unaltered. In no way can I guarantee this service, nor be considered responsible of any content re-transmitted. The only purpose for this relay to exist is because lot of people who do not have equipment or are located too far from station seem to be interested about listening to it. Note, that because of shortwave radio signal propagation specifics the station is not always audible

Temporary Repeater is .. Temporarily Back!

It has been a while and definitely too long! 

When the repeater was started, it was deliberately named "Temporary Internet Repeater", because there was no idea for how long I'd be running it. The site was running self-sufficient for quite many years and then the infrastructure components started to become obsolete one by one. 

The Shoutcast audio delivery servers used for streaming audio, disappeared and Hostgator started to hate me for keeping hundreds of gigabytes of audio archives online. So while my radio setup kept working reliably, the repeater as whole, decomposed.

However, looking at the news and thinking what the UVB-76 really is, it made sense to start doing a little  dusting off and bring the repeater back alive!

Today is just a first step after a relatively long time in hibernation. The archives are still broken, as is literally the whole site. But most important thing, the repeater itself, is now online. As there are literally no audio-only live content delivery servers anywhere, the repeater is back with the video this time. It is a realtime capture of my HDSDR software defined radio screen.

The hardware today is the same faithful Soft66 Lite SDR radio that has been in service all these years, connected to the Focusrite Scarlett 2i4 soundcard and to the laptop from there. Antenna is the same 1m diameter magnetic loop as always.

The video is delivered to the wide world using KeyCDN servers. As this is an affair involving money, the upcoming weeks will tell, if and how its going to look like and how small the video window has to be trimmed to reduce the number of outgoing bytes! :)


  1. What do you think is the purpose of UVB-76?

    Did you see that the frequency was temporarily taken over in January?


  2. Thank you for the pointer to VICE! Will make a post about it as well.

    As of the purpose, it is probably a multi-use station. While russians have never confirmed its actual purpose, the station should have enough importance that it has been maintained for past 40 years, has survived a regime change in 90-ies and was reorganized together with russian military reform a decade ago.

    The best guess is, that is its a part of the some sort of ionospheric sounding beacon used to measure shortwave signal propagation, doubling as channel marker (for both, commcheck and keeping the band allocated), with occasional use for voice messages.

    All that sums up as it could very well be a long distance comms channel of last resort if everything else has failed (digital modes at higher bands and satellite).
