@fribbledom That is an interesting sound indeed. For people not listening to it, what I assume is its normal buzz is only going briefly every couple seconds, and there's a repeating beeping sound, maybe another station given that the WebSDR seems to need a higher gain to pick up the beeps clearly.
@fribbledom I don't know much about these so maybe what I'm describing makes more sense than it does to me.
I've took a look at a Russian forum discussing it, they were talking yesterday about The Pip in the Buzzer's signal, seems to be it?
