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

Receiver Upgrade for Listening Station!

I am glad to announce, that UVB-76 Internet Repeater has now its dedicated SDR (Software Defined Radio). The receiver is called Soft66lite and the improvement is nothing short of spectacular. It looks like this:

I have used to think that Icom IC-R20 what was used so far is pretty good radio receiver, period. The reason for replacing it was just that I wante to have my scanner back and therefore was looking for inexpensive replacement. The $18 soft66lite was pretty much the only alternative found on eBay and I had no problem having it in kit form. As this is fixed center frequency, the component needed was also a crystal with the frequency close to 4.625MHz. Got 4.608MHz from Elfa, which is good enough for tuning in with 48kHz sample rate soundcard.

I was stunned to find out, that the $18 receiver did way better than Icom had ever done with weak receptions! I am running it with ordinary long aerial of about 10 meters and as of 6pm GMT, Icom hears nothing with its magnetic loop, when SDR has audible signal. When I use Icom with aerial, the RF stage overloads from noise.

The station uses WinradHD as SDR software for tuning in and demodulating the signal. Despite some quirks on soundcard handling, it seems to be the most straightforward SDR software today. The screenshot looks like this:

So, as of now, the setup for monitoring station looks like this:

10m aerial antenna -> Soft66lite SDR -> Computer with Behringer BCD3000 -> WinradHD Software -> Virtual Audio Cable -> Edcast Standalone -> uk3-pn.mixstream.net

Happy Listening!
