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.

Now Streaming the S30 "pip" (3.756MHz USB)

With the UVB-76 off the air, theres time to provide some other listening besides. As told, I am trying to put up a "Weekly Live Number Station" show here and the most obvious candidate for the buzzer companion feed was the "pip". Here is why.

As the the case with UVB-76, the "pip" is transmitting a continuous channel marker. Instead of buzzing, the sound "pip" is used .. well, thus the name. And exactly as on UVB-76 case, it transmits voice messages every once and a while. One example can be found here. (Sample reference: http://hfsurfing.blogspot.com/2007/03/why-pip-named-s30.html)

The "pip" is a little bit more complicated to monitor tho. Namely, it is transmitting on two different frequency: 5.448MHz on nighttime and 3.756MHz on daytime. When I can quite clearly receive the nighttime feed, the daytime still needs some antenna work, so far I haven't been able to get any signal from 5.448 in some reason.

So, what is it then? If you browse the internet archives, the document here describing the UVB-76 also mentions the "pip". It is considered by this source as part of the military network, "North-Caucasus military district, Rostov/Don". As the document is a translation from similar russian booklet found here,
A nice reference about the "pip" can be found at Here.

The link is at the top of the page, labeled "new". Note, that this station is farther away than the buzzer was, so one can receive it only here during the nighttime at the moment!


  1. Ah, the Pip. I found this as fascinating as UVB-76. ...not like I can really hear it until I get a better receiver. I've had to make do with Conet recordings.

  2. Apparently UVB-76 buzzer is back.. Listening to it now on the USB feed.

  3. I hear the buzzer too. It sounds different, though. Listening to AM. Perhaps another jerk playing a game?


  4. I'm hearing it from switzerland on USB as well (globaltuners)so i doubt its fake. (someone with that big of a transmitter would have gotten busted already)

  5. Hmmm, its true, the buzzer is back i listen in the moment in AM on 4625kHz...

  6. Hi again,

    yes, this is the orignal Buzzer.
    1. Transmission in AM
    2. Harmonics on 4667,6 and 4710,3kHz
