Reception of the UVB-76 signal on 4625kHz has been disturbed for last two weeks or so by an unknown noise source. I have had no luck figuring out what it is so far, but it does look like a network-over-powerline thing someone could be using at the neighborhood.
Judging from 24-hour waterfall pictures it has no relation to shortwave propagation effects (i.e. has to be relatively local) and does not change in frequency nor time, so it cant be from street lighting, phone charger gone grazy, plasma TV etc. It is also apparent with other radios I have, so it is also not the equipment at the streamer.
The noise stripe is repeating itself after every 50kHz from 2MHz to around 6MHz effectively rendering my shortwave capabilities to nil and does not seem to have plans for going away, so I'll have to start searching for the source!
DISCLAIMER
IT IS TIME TO TAKE SIDES
During almost 12 years the repeater has been up, I have been keeping it apolitical. But Putin has gone batshit and UVB-76 radio station is a weapon. So, while I keep translating it, you are welcome to also watch the Ukrainian news channel '34 Kanal' to see, what kind of events this signal is actually participating at today.
Slava Ukraini!
