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 AM-modulated 900km 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. Should the UVB-76 station- or transmission content owners feel violated in any way, please contact me at uvb76.repeater@gmail.com and we will work it out.

Note, that because of shortwave radio signal propagation specifics the station can be more or less reliably received from around 4pm to 6am GMT on summertime. It is almost 24h audible during the winter, with short "skip-zone" blank-out around 6pm GMT.

The USB feed is considered as main source of audio today, as the voice messages are much better audible there than on the AM stream. However, the buzzer sound from the AM stream is somewhat more pleasant to listen at, so both feeds are kept simultaneously.

Streamer WinradHD screen now online

The faithful ICom R-20 has been replaced with Soft66Lite SDR for quite some time, so is now the picture at the blog. 
Thanks to Mat, who gave me an hint about ManyCam, the WirdahHD screen is now live! 
It broadcasts through Stickam and does not have a smoothest video response one could wish, but if you click and zoom in, it will give you quite nice overview of what is going on at and near the UVB-76 spectrum.

One thing tho - the shouthcast is buffering about a minute worth of audio in order to guarantee skip-less playback of the audio. Therefore the streams are 1 minute behind the WinradHD screen. You are _receiveing_ the signal almost realtime, but your player is playing from the buffer. There are hacks around to disable this buffer, but they are really complicated. 
Then again - if you see morse or anything else interesting passing by on the video, you have this 60 seconds to start your recorder! :)


  1. This is great to have. Did you know about WebSDR, though? Try some examples out here:


    I don't know much about amateur radio, but this service sound like it would be very beneficial for this site. You may be interested in taking a look at it. Not that your site needs changing, though - it's really good the way it is, and I really appreciate that you're providing this to all of us with little benefit on your part.

  2. Thank you!
    I love WebSDR and have been talking to the guy who has created it to set it up here. The problem is, that it needs a massive bandwidth to operate (my 2Mbit outbound connection will handle about 5 WebSDR users). Considering the interest about the stream, it is pretty useless this way. But I will set it up any day soon and see what happens.

  3. Ah, I see. I assume you'd probably need to get your own servers to provide a much higher bandwidth, which would mean big $$$, unfortunately. I hope my $4.70 donation can eventually go towards something like that in the future. I wish you best of luck for what that future may bring, such as a WebSDR feed.

  4. Also, couldn't you relay the WebSDR feed to another server, and everyone accesses that one? It would only require you to send it to one user at any given time. That seems the most viable alternative for the time being. However, I assume there would be costs involved, which donations may or may not cover. Still, I see no reason why something like that wouldn't work if you could find a way to do it.
