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.

"Backward Music Station" or "Whales" on WebSDR

Ther is a rare(?) opportunity to listen live to an unearthy phenomena what is described as "Backward Music Station" on a WebSDR. While the WebSDR project is worth a gold star all by itself, the backward music station is nicely located inside an amateur band. Just tune in to frequency 3634kHz with LSB modulation and enjoy!

For those not having shortwave receiver in their posession, the WebSDR is an excellent site to explore! It requires Java to be installed tho, but its worth it.

  2. found another possible number station on http://websdr.ewi.utwente.nl:8901/ located at 3756khz on lsb

  3. apparently it is the pip numbers station per http://www.cisquet.nl/numbers.htm

  4. Try playing the 'backward music station' at X3 speed - all the high pitched noises become too high to hear and the low pitched grumble sounds a lot like a human voice reading out numbers, although they're not clear enough to hear.

  5. ..actually, this only works on the sample on the irdal cd, disc 4 - tried it on other samples and it doesn't work because it is a completely different source. There seems to be different stations referred to as 'backward music station'.

  6. 3594 kHz NOW! Fantastic noise/ambient/psychedelic!!! :O

  7. Very good, the author is also very talented, you have succeeded in conveying this information to readers, thank you very much, wish you success. The article gives me a lot of useful information, I think it is very necessary for everyone, hope that more people will know your post.
