UVB-76 On 4625 Being Spammed/Jammed By Pirates?!
« on: January 23, 2022, 0307 UTC »
There's an article on Vice.Com that Russian spy station UVB-76 on 4625 is being interfered with by pirates, possibly from the Ukraine.  Crazy 4chan-type "meme" images and music are being viewed or heard on SDRs.

However, the article's writer does not know much about radio, as he states that SDRs are being used by pirates to transmit the interfering signals.

I heard someone whistling on there just now. Recording just in case it gets interesting.

0356z whistling, sounds like a tune up, pretty strong
0401z music now, much weaker than tune up signal

I used the uTwente "WebSDR" to see the waterfall display of the buzzer. I got a good recording of at about 00:30 UTC Feb 4, 2022 of the broadcast. looked like someone was broadcasting 2-4 letter messages in about a 30 second loop. If I had to guess I would say it was "дер"(der) "yp"(ur) and "ye"(ue). I really don't know though. As of 04:42 UTC Feb 4 2022 the "trolling" was not broadcasting. -Nuke X

both the buzzer and the jamming and are coming in quite well on the W1NT SDR in Newton, NH right now, a song is playing that oddly goes well in time with the buzzer, lol.
Here is a recording of some of the music, will make another if something more interesting plays https://vocaroo.com/1a6r3bimwJi2

23:12 a single word/phrase is being repeated over and over now, not sure if jamming or part of a real broadcast https://vocaroo.com/1e1ZU21pnB8k
23:14 Jamming seems to have stopped for now
