DISCLAIMER

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.

Quietly Upgrading

Back in 2010 when the UVB-76 Temporary Internet Repeater was set up, the political situation was very different from what it is today. The Buzzer looked like an obscure artifact from cold war past and filled the minds with technology mysticism.

Today, the buzzer seems more .. relevant. We are still not exactly sure of its purpose, but for whatever reasons it got upgraded 4 years ago, it seems to keep doing what its meant for.

And so will be its internet representation, so I am in a process of doing some smaller and larger upgrades to the repeater.

As a first in series, the main signal processing software what captures the signal from radio and processes it to a stream, has been upgraded from relatively old WinradHD to its current offspring HDSDR, version 2.70. The reason was mainly a stability, but as a bonus the 24-hour waterfall has now a nice time scale printed on the left side.
